Isn't it funny that I used water injection way back in the late 70s on my custom-ordered 69 Chevy Caprice to increase the power of the radical engine my grandfather had built into his brand new Caprice. He ordered the Corvette 350 instead of the stock 350. Stated difference was 25 or 50 hp but they underclaimed the HP for these engines as we know. Then water injection kind of was forgotten about for the most part. Cheers

My father did this back in the '80s. Just fed it into the carburettor, rate controlled by a choke-style cable in the dash. Worked reasonably well so long as he remembered to adjust it when stopping. He was working on a new system, basically taking 4 cylinders of a V8 to have them run as a steam engine using the exhaust from the other 4 and injecting water. Had a weird manifold welded up to route said exhaust around but was really struggling with making the custom cam. Only so much you can do with a stick welder and a bench grinder :) A man of ideas, he was. The stuff he could have built with even half the tools I have now... his first job was lighting the boilers on locomotives. He knew steam. Bet he could have made it work with the right tools. Oh yeah, he did tell me about an earlier project he had... dual carbs on a gasoline engine, one normal and the other fed with jet fuel. Big old rod going through the dashboard to switch between the two. He'd switch to jet fuel once up to temperature and running down the highway. But, that was only because he was working on a airbase at the time and could steal all the jet fuel he wanted. Ran the house stove on it too (yeah... oil stove... long time ago). Anyway, thanks for the memories :)

WHAT?!?!!? I'd love to see even a somewhat working prototype of this SteamGas Engine. That's crazy!! Might work better with smaller pistons for the steam, though. Could put them closer to the chambers to help cool the gas cylinders. But man, that's a lot of moving parts.

[@4Fixerdave]

@@korishan Not really any more moving parts... just extra plumbing. I was 15 at the time and, honestly, I can think of a few reasons why it wouldn't work today. But then I can't say I really understood all of what he was attempting. Like, he was modding the cam to open the valves every stroke, basically dual-lobbing them. Maybe that was how he intended on dealing with all the expanded exhaust from the IC side? Always 2 cylinders drawing in hot exhaust from 1 IC exhaust stroke, a 4-stroke IC feeding a 2-stroke steam plant. I could see the exhaust rotting away pretty quick... but then how much exhaust would it actually need? Anyway, not the first engine he had cut in half. There was the inline-6 cut down to 3 for the PTO planer truck that he used to finish the boards cut with the sawmill he built out of car parts. Or, the Damnation Ally style 6-wheeled stair-climbing hand-truck, or... man had a lot of faults but being stuck in a box was not one of them. Old-school Maker, though trained in HD and auto mechanics... he knew his stuff. People like that are still out there... like the ones that took a little OHC 4-cylinder engine, pulled the head off, and stuck an electric motor in its place. Basically driving the crankshaft and existing drivetrain with a motor as a cheap EV conversion. Good idea? Probably not, but they're running an inefficient EV while I'm still pushing an even more inefficient IC engine around. Credit where it's due.

[@rocketsurgeon11]

The only reason running Jet A was any benefit was because he could get it "free". It's basically more refined diesel. I'm actually surprised it ran on it at all. Unless it was actually just avgas, which would make more sense.

[@4Fixerdave]

@@rocketsurgeon11 Yup, just fancy kerosene. He worked at the base fire department and they had a pit full of barrels the plane mechs dumped, possibly contaminated fuel. Just something for the fire crews on practice days. He'd go out, crack open a barrel, soak a rag in it, and if he could get it to burn, he'd pump it into his second tank. And yes, he said it was a mess (lots of smoke, hard to start) if he forgot to turn it back to gasoline well before he had to stop. Only reason was because it was free (in that nobody cared if he snagged some). The main point was that he'd drain half that tank for the stove when he got home. Burned better in the stove. Oh, Churchill Manitoba... winter. Cold... like polar bear cold. Back in the days when the kitchen stove was the heat for the house and insulation was the snow drifting through the cracks in the walls. Said the top of that stove glowed red hot all winter. He lived off-base and had to drive to work and back, quite a ways he said. That was his routine: after work, snag some fuel, drive home, drain the tank to fill the stove, take the battery out of the car and put it on the oven door to keep it warm. In the morning, slide a cookie sheet of fuel under the oil pan of the car, on fire, put the battery back in, then start the engine. Drive to work. Got to park inside at work. No, I don't recommend the cookie sheet block heater thing with today's cars ;) Yeah... more essay answers. Sorry, memories.

[@ratmanmurray7137]

An old mechanic I knew explained water injection to me in a slightly different way. If you ignite a fuel/air mixture, it expands itself by about 7 times, moving the piston... water being superheated (like in a steam engine) expands about 20 times... so, if you add water to the combusting air/fuel mixture, the water expands 20 times it's size and takes up room in the combustion chamber so it adds it's expansion to the air fuel expansion going on in the cylinder, which adds up to more bang. Funny story, after I learned this, I added a home made water injection to my Holden (Australia) V8 motor (similar to a small block Chev). I used a water bottle with a fish tank clear hose to a port on the carburettor, with an air valve (from a fish tank) to limit the flow of water. With the motor running, I adjusted open until steam was visible out of the exhaust then closed the valve until the steam was not showing any more. It worked well, had to fill the 5L water bottle every few weeks. A few years later, I rebuilt the engine and I realised the port on the manifold I had used only went to one side of the engine... so, one side head had intake runners, ports and valves were as clean as new, no carbon what so ever... the other side, the whole thing was as sooty as expected. The heads looked like they came from different engines. I recommend water injection on any car... more for longevity than ultimate performance... water injection is probably not yet successful because fuel companies can not (yet) make people pay for water... and using water would lower the fuel bill... so, that would be detrimental to fuel sales (so, better not encourage that) haha Greetings from Australia

[@luckygen1001]

Steam expands 1700 times from a liquid to a gas.

[@djole02]

The expansion ratios are completely irrelevant. What produces power is the AIR that gets expendanded, not the fuel or the water. Adding water to the air reduces the volumetric efficiency and power of an engine at the same operating point.

18:55 reusing water from the AC condenser for this purpose is honestly brilliant!

[@TheAruruu]

it really is. when are you most going to need water injection? when it's hot. when are you most likely going to be running the AC? when it's hot. it's literally a water generator that really only runs when that water needs to be used! it's genius. Edit: oh! and there's another brilliant part. it's distilled water. condensation is literally distilled water, so there's never any concerns about that water having things that need to be filtered out, growth (algae) aside.

[@Jakob178]

idk i think its a source for problems. What if the water mix with something else? imagine the airfilter have a hole and some insects will injected into the engine. Why they dont use some good old 5 litre watertank? This will work for weeks and the water is separated from everything else. What if you drive in winter? only dry air no more condense water. Put some Ethanol-water mixture and it will not even freece.

[@Scot-p1v]

I love the idea, but, as an HVAC technician, have serious reservations about the reality. Car AC drains stop up fairly frequently due to sludge & slime. Even if the system is perfectly sealed and no unfiltered air hits the evaporator, no filter catches all particles. Let’s be honest: many-most in my personal experience-people are not good about changing filters on schedule. And, who hasn’t found leaves, bugs, or even a desiccated lizard in the bottom of their filter box? You’ll definitely need a filter for the condensate you collect-which will be another maintenance failure point. I’ll just put distilled water in my tank, thankyouverymuch. Mind, I’m sure manufacturers can figure it out & (mostly) get it past the warranty period, but I wouldn’t want to buy any of the first few years of production….

[@allanallansson9532]

The water condenses on the evaporator (the cold side) of the AC, not on the condensor (the hot side).

@@allanallansson9532 as an HVAC tech, I daily clean sludge from condensate drains & traps-and I’ve seen the crud in the pans of automotive systems. Dust finds a way in. My point is that one would want a secondary filter for the condensate, and that would need to be easily accessible

There are a lot of different washer fluids out there. A shortcut to telling the alcohol percentage is to look at the freeze point. Where I'm at, you can buy summer washer fluid that freezes at the same point as water but has some detergents and crap to work on waxy bugs. The winter fluid will have more alcohol, and the really cold-weather winter fluid will have a bunch.

Cooler combustion chamber means reduction in NOx emissions as well!

[@d4a]

Yes!

[@jasonrr9817]

And if we can reduce NOx with water, cleaner top engine from use, and even cleaner still because it could potentially allow us to dropkick the EGR system into the trash where it belongs. Or at least use it solely for holding pressure and not for strangling the engine to cool it. (At least that's what a big part of EGR used to be...I'm getting old😋)

[@Appletank8]

EGR functioning properly is supposed to only to activate at low throttle

[@sinusspass1998]

And with condensing the water from the exhaust gas, we could re-use it. Question would be, how much water could we inject and what could we get from this. So actually, what could a crazy tuner do if he doesn't care about water consumption? Water has a really nice expansion by transitioning to vapor, so I'm quite sure it is a part of the power increase or may become one, turning the engine into an internal combustion steam engine. Just a thought, I lack the experience in real working on engines or cars in general and a project car to test it myself.

[@jasonrr9817]

@Appletank8 my first diagnostic in the field was egr stuck open causing rough idle. Egr opens at high throttle to cool combustion with non combustible exhaust gas to reduce nox emissions. Mazdas 2 stroke valved engine uses it at low for pressure maintenance but the dirty gasses at even lower Temps like this could potentially foul combustion chambers faster

[@jhoncho4x4]

I used water / methanol injection with my 10.5:1 LS1 on hot summer days; running the A/C with 87 octane fuel and loaded with people. That worked much better than running 93 octane; which varied greatly in quality. 100+ race gas worked too, but was expensive per gallon. The methanol injection system was the cheapest way to daily drive that car in the summer. The cold air allowed 87 fuel during the winter, and no methanol was needed. An adjustment knob allowed me to fine tune the spray amount, as driving conditions changed or turn it off completely. I tapped the windshield washer tank for the reservoir. Held about 1 gallon and windshield washer fluid is cheapest during hot summer months. I would top it off when I filled the fuel tank; reservoir never ran empty. That system worked much better than trying to find decent high octane fuel; the quality is hit and miss while not stopping the detonation, just less detonation. Car still had no power and had to drive carefully to not sound like an Olds diesel. The methanol injection was capable of eliminating 100% of the detonation and restored about 80% of the hp; car could be driven like a normal automobile.

[@Drunken_Hamster]

@@jhoncho4x4 Something was deeply wrong with that engine to run that poorly at only 10.5:1 compression.

You can also spray water over the intercooler.

[@sheeshulex]

GD generation Impreza WRX STi had that function if the memory serves me right

[@ivertranes2516]

Or add a fan to drive air through the intercooler. Or even both!

[@JETZcorp]

​@ivertranes2516 The fan may be extremely functional or near-useless, depending on the specifics of your car. For example, in my car, any intercooler gets mounted right in front of the radiator and AC condenser in a semi-ducted V-mount. One fan pulls through the whole stack, and you can turn it on manually with the AC controls (lol). If the intercooler is quite separate, and especially if airflow is questionable, a dedicated fan will be a huge improvement. The biggest thing you can do is make sure the air has a good escape route after it's passed through (eg. hood vents). If there's a high pressure zone behind any heat exchanger, air will go to great lengths to go around it. On some cars, you can put spray nozzles in front of a heat exchanger and never get it wet because the airflow is so bad. Fans brute-force the issue, but nothing beats natural airflow.

[@zanzabar4ky7]

That doesn't really do anything for a consumer vehicle, and it does not solve heat soak related issues due to bad airflow. It is a small gain and mostly good for cleaning.

I'd really appreciate if anyone clarifies this exact point, AND if this 'expansion' would affect the final power outcome. (IMHO, this topic deserves a Part #2). Thanks D4A for your in- depth reviews regarding topics (Almost..) nobody talks about!!. 😉💪🙏🙏🙏

[@klausbrinck2137]

I can tell u this, but it doesn´t answer your specific question: One can use this system for a single cycle, and re-use it in the next cycle, but this time without fuel. always alternating. In described 2nd cycle, the piston still turns the crank, cause of the water straining the cylinder-walls of their heat and expanding. In this case, where in every other cycle the water-mix doesn´t coincide with a combustion, one shouldn´t waste any combustible and expensive ethano/methanol, to mix it with the water, but instead, take pure water. How do the 2 types of expansion compare to each other powerwise??? No idea...

[@fukkitful]

The steam expanding wound increase cylinder pressure. Which should increasing power. Not sure how much increase though.

[@hernandovillamarinbuenaven7476]

​@@klausbrinck2137 : Thanks for the insight on thermodynamics!!. 😊🙏

[@touristguy87]

​@@klausbrinck2137 the exact same rules apply, dude. If you don't have combustion and you're attempting to run the cylinder off of heat transfer from the cylinder material to the expansion material, then the expansion material stops expanding on its own when the exchange of heat energy stops. You've already gone through one cycle before this. Your idea would not work at all unless you don't allow for exhaust from that cylinder. Otherwise the cylinder would be largely devoid of expansion material as it would have been pushed out of the cylinder in the preceding exhaust stroke. You'd still have the intake and compression strokes if the intake valved opened and closed and that would then fill the cylinder with what, exactly? Just air? Air and water? The incoming air and water would cool the cylinder walls and the piston which are already being cooled by the cooling water and oil sprayed on the piston. It would make more sense to run the piston through an additional complete cycle without opening the intake or exhaust valves, to do two power strokes with the same intake charge. After the first power stroke you'd lose energy to the following exhaust and intake strokes, simply by heat transfer as you stated, you'd then have a compression stroke before the 2nd power stroke. Now your only problem is in managing the engine harmonics since the 2nd power stroke would be out of balance with the first. Multiply that problem by the# of cylinders and again by the # of cylinder banks. Or you can just use a turbo and recover some of the energy wasted by the first exhaust stroke. Use an intercooler and you'd recover some of the timing-advance lost by the fact that you've now heated the intake charge. Or you can use a turbocharged diesel-electric hybrid with an integrated high-voltage low-temperature power-distribution system. I think that's what Dr. Ferdinand Porsche used in his prototype Tiger tank in 1941.

If it's not mandated, then will the AVERAGE customer be willing to pay for it. If not, then it won't go into mass production. Possibly the only manufacturer that could get away with it is Porsche.

SAAB sold a water injection kit for the 99 Turbo and there you had to mix water with windshield washer fluid during winter, maybe even all year round. Think it added 20hp with raised boost. So from 145 to 165hp from a 2-litre engine which must have been really impressive in the late 1970's

[@GavinM161]

I was waiting for him to mention the SAAB 99 and surprised he didn't.

[@lsswappedcessna]

the second mass production turbocharged car in the US, the 1962-1963 Oldsmobile F85 Jetfire, used a water/methanol injection system as well. It had some complicated vacuum control system that would bypass the turbo if your water/meth tank ran out so you didn't destroy the engine. They used aluminum 215 ci V8 engines and made a respectable for the times 218hp. The biggest downside of this system other than the complex vacuum safety system was the 215's overheating issues, likely exacerbated in this case by the extra power. All in all, they were cool cars but I'm glad my F-85 is a few years newer and has a naturally aspirated 330ci engine, less vacuum hose spaghetti to deal with and no need to homebrew a water/methanol/rust inhibitor cocktail of my own to make the turbo actually do something.

@@gorkzop The car I drove in the driving school back in 70's was a turbo Saab. On one of the first lessons we stopped at the red lights and I forgot to change from 3rd to 1st gear (manual gearbox) - when the lights turned green we did proceed normally. The driving instructor pointed out my error stating quite laconically that in other cars that would not have worked.

[@touristguy87]

LOL why must it have been? Impressive in the late 1970s was 400hp from a 1.5L naturally-aspirated engine. Still paled in comparison to 400ft-lbs of torque from a 7L engine. Because torque is what determines acceleration. HP only determines top speed. The gap between torque output for a 400hp 2L engine and a 400hp 7l engine is what has driven transmission development. You're talking about ww2 engines that were roughly 1800 cubic inches. The Packard-Bell Merlin in the P-51 was only 1600 CID and only produced 1300hp. The Japanese Zero radial engine also produced 1300hp. There are many chapters of engineering technology standing between the two engines. The quintisental WW2 fighter engine was the Double Wasp in the Vought F4-U that produced about 2000hp. I say that based on the fact that the F4-U remained in production into the 1950s. You're talking about engines under 2L, the discussion switches to high-revving engines, pre-turbo post-supercharger, for applications like motorcycle-racing and Indy-car, maybe F1 racing. You're diving into a pool that is way beyond your depth. Find another topic in which to pretend to be an expert.

It's really a no brainer. Distilled water sales would increase, engines would make more power more reliably, exhaust would be cleaner, and less NOx would be produced. The cars are already running external electric water pumps, it's not like the hardware isn't already in the cars to do this. Run a few extra lines and another tank and you're good. Now you don't need auxilary port injection(since steam cleans the engine, which means fewer valve deposits), or you can convert the aux port injection for water/ethanol mix.

We did this in the 70's with our air-cooled VW's. We put a windshield wiper tank and pump in the backseat with a hose to the top of the air cleaner. A manual switch turns on and off. We tested the cylinder temp with a sensor under a spark plug. Running at 70mph in LA heat could really cook those little 1600cc engines. We found temperatures reduced greatly, but no fuel or performance improvement regardless of the alcohol mixture. Pulling the heads off we were surprised how clean the pistons and exhaust valves were. We gave up on the project, but whenever someone came in for a tune-up, we ran the water spray for about 30 min on the highway and it removed a ton of knock and pinging.

[@jackandblaze5956]

I used to dink around trying to boost power and mileage with bolt-on mods on all my old cars including my 69 Bug. On the bug, the nicest, quick cheap combo I found was a homemade (plywood) air cleaner that used a paper element from a Plymouth Duster slant-six. The aftermarket had paper air cleaner conversion kits but they were extremely small filters and eliminated the velocity stack that was built into the OEM oil bath air cleaner. In the OEM design, the built in velocity stack was a great idea but the oil bath system was too restrictive. Eliminating the restriction by using a large paper air filter and fabricating my own velocity stack inside the air cleaner box, I then had a noticeable increase in power. The only other mods were that the car already had a cheaply rebuilt 1600cc engine with heads that had been milled a little too much, and a freer flowing "Monza" exhaust. With that combo I could bury the speedometer until it hit the peg past the 90 mph mark. I was pulled over by a sheriff one day & he asked me if I knew how fast I was going and I didn't have to lie when I said "no" because the speedometer was literally pegged. He said it was over 115 but started laughing for some reason and let me off with a warning. I was aware of water+alcohol injection and the engine would knock if lugged on a hot day, but I didn't get around to trying it. It was good enough already. After that I helped a buddy turn his gas guzzling 74 Trans AM w a 455 into a gas sipper by building an 11 to one 327 and swapping the automatic out for a manual and a taller rear end. We did put water+alcohol injection in that engine and the car would get 22 mpg in town and 27 on the highway. Not really good enough considering the amount of work put into it. He soon sold it and bought a VW rabbit which already got over 40 mpg without having to modify it. Then he had a head-on collision with a Plymouth Horizon. The driver of the Horizon had broken legs, my buddy in the rabbit was killed instantly. I later bought a Horizon and found out that Horizon/Omnis had HSLA steel frame rails when a Ford Escort hit me head on. The Escort was totaled but my Horizon had $250 of damage. I know that was long-winded but one thing kept leading to another. But in our quest for higher mileage and more power, safety was not a high priority.

[@robertblunden7160]

That's because the water takes the carbon off the piston and the sides of the piston.The carbon builds up like a seal on the side of the piston to stop oil burning or blow pass. Carbon is good for sealing. If you want to clean the top end of your engine, a cup of water will clean all the carbon of the piston and valves.

[@roshane.nanayakkara]

@@robertblunden7160 yep the plugs are always very clean with water being injected and there is minimal carbon buildup. I think a small percentage of the oil also gets steam-cleaned out which is why the oil levels need to be monitored more often.

But it does evaporate faster than water, vapour is a compressible gas and it adds energy to combustion.

I highgly recommend you all to learn more about the brazilian experiencie, and to know about Proalcool Program from the 1970's. 😉

What about corrosion and lubrication? Doesn’t this water affect the engine tendency to wear?

[@haku1155]

Yes and no. Lets look at what might happen: Water will not mix with oil easily, oil is put on the cylinder wall and also removed by the piston rings, they seal the chamber from burning oil and from injected fuel leaking into the oil system, so in theory they will also seal off the water from going into the engine oil. Since no seal is perfect, every engine will burn minuscule amounts of oil (except VWs they burn a bit more) so the water/ethanol mix might slowly creep into the engine oil as well, ethanol being a great solvent might make the oil thinner (same as when your fuel mixes with oil) while the water will emulsify with the oil eventually into the ever beloved cursed foamy caramel pudding from hell. Because of that, it might make make oil change intervals shorter, which isn't a bad thing per se. If that happens to be introduced into the mass production cars its certainly a thing thats going to be tested on the customer. Corrosion is another topic. I doubt it will be an issue since the water-ethanol mix is short lived inside the engine and most modern intake manifolds are made from lightweight and corrosion proof polymers. The water evaporates (being innate) and leaves through the exhaust system while the ethanol burns. The water might even have a positive effect on emissions as the bad parts NOx are the Dioxides (NO2). There will be more NO2 the hotter the whole combustion gets, so by cooling the chamber effectively you can reduce NO2 emissions.

@@haku1155 thanks for your input. However I am still a bit concerned. Water does not dissolve much in oil, true, but it may emulsify. As for its evaporation, certainly that happens, but I suppose it is a matter of rates. If water does not get removed at a fast-enough pace, I suppose it could lead to accumulation in the crankcase and there I am not so sure every thing is corrosion-proof. Also it is true as you say that NOx can be reduced, but water can increase oxidation of the oil, which may lead to faster than normal replacement. I am not sure, if that is the scenario, that people will be so happy to change the lubricant. But , I guess that this is taken into account by whoever company believes in this technology.

[@RobertBeck-pp2ru]

If you are one who constantly "gets on it" at every light or straight away, you will no doubt begin to see a coffee colored slime on the underside of your oil filler cap. It's a warning sign to change your oil. If you use full power only occasionally, say for merging into freeway traffic, most of the water vaporizes away in normal driving. Even so, it's a good idea to shorten the oil change intervals if you equip your engine with water injection.

[@juriedekock6154]

You are right.....Do not add water when driving around town or say the last 20 km of your trip

[@johnflynn6140]

6700nm of torque holy crap with 5000lbs of torque your going to rip off the rear end of the car, lmao of course I am kidding and know its a mistake

[@jhuck8166]

I had a diesel truck that would overheat when we towed our RV in the Rocky Mountains. A 15-gallon tank, 12v water pump, cheap 1/4" irrigation tubing, and a few plant misters took care of the overheating issue. The mister nozzles sat behind the grille and in front of the radiator. It was cool to see how quickly the misted water would bring the temperature down.

[@99redpontoons]

Honestly, coolest part about watching this is that this technology came about for use in fighter aircraft during ww2, and now it's just applied to automobiles as a hobbyist project. Ethanol-water injection into your engine was a typical method of implementing an 'emergency power' system in high horsepower aircraft like the F4U corsair that would grenade if they were pushed up to any higher level of supercharger boost, and was also one of the means by which a P51 mustang could achieve such heinous levels of acceleration.

[@adamkucera3343]

Thats some real power! Honestly was not expecting you to reach these numbers based on the build (coming from a 2ZZ guy). True eastern european dedication

[@formerice]

Ran that set up on a supercharged Tacoma for 140,000 miles. Worked great. It added a fair bit of hp on the dyno, but allowed me to tune without detonation, most importantly.

[@barry7608]

For some one who might be classed as a rev head, I find your ‘drug’ like videos addictive !!! Always well explained and will I ever stop clicking on them ? Maybe but not yet ! Thanks again

[@kkulikov]

I tried water injection many years ago with my Micra. The conclusion was there is not a big difference but when I took off the head of engine I was really surprised. It was so clear inside!

[@younouloveit1]

Hey wanted to share a tip I picked up for boost hoses that like to pop off. I found, if you wire wheel the area that the silicone meets the aluminum pipe, not only will the hoses never separate, but you'll have to run a pic around the silicone before removing it the next time. It's that tight! Some people say hair spray and I'm sure they're are a ton of other options people will suggest... I personally just found this to be a very low cost, super effective solution.

[@Pitchplus8]

im using ethanol Water Injection in my B58 running it 25tkm and its running absolutely fine. You can still read the QR Code on top of the piston and the sparkplugs are nearly white as a new sparkplug as i changed it.

[@moots13181]

Awesome job! Totally agree that water injection should be way more common. It's not on commercial production vehicles because water freezes and expands. That problem would require air purging of lines every time the vehicle turns off and before the temperatures in those lines gets close to freezing and/or an alcohol mixture. If part of an essential tune, the engine might be damaged WHEN the fluid runs out. People would most definitely NOT take care of it properly and warranty costs would be enormous for the manufacturer.

[@michaelhevezi7273]

Water you doing?! :) One thing I would add to this talk about pressure and power with water injection is a comparison of volumetric expansion. When water hits its heat of vaporization (212 F) nothing can stop the expansion (which is why steam engine horsepower is about limitless, check out speeds of early motorcycles) and the expansion is approx 1600 times its original volume compared to around half as much from modern pump petrol. So when you have three players in the combustion chamber with all kinds of different attributes when is comes to expansion, heat of vaporization, and the interactions with one another things can get a little complicated, at least for my smooth brain. Big fan of the underdog developments!

[@RobertBeck-pp2ru]

Here in the states, we can buy E-85 gas, (85% ethanol, cheaper than 87 octane) and mix it with 87 and water (distilled). Some guys use it in n.a. engines, but the real benefit of the mix goes to turbo engines with intercoolers and a quality control unit. Excellent topic Drivin.

[@reedsilvesan2197]

Ive been using sno performance injection in my class 8 semi's for about 10 years. These big diesels really come alive o this stuff. So much that my bone stock c13 out pulled even 600hp c15s. Also, it SIGNIFICANTLY assisrs the cooling of the engine. Very impressive stuff, wouldn't run my semi without it. It SIGNIFICANTLY reduces EGTs, and that extra heat that was going out the exhaust pipe is used to push the piston down much harder.

[@AltairDubay-lr6bs]

Hello, excellent video. I'm from Brazil, and here we have the option of filling up with ethanol (older people here call it alcohol). Ethanol sold at gas stations contains around 8% water and 92% ethanol. And it costs around 30% less than our gasoline (our gasoline contains around 25% anhydrous Ethanol, without water).

[@Fred-rj3er]

I never even thought about why some cars have intercoolers! Again, more science explained in an absorbable way.

[@hugueslecorre4893]

This was used on rally cars I worked once for Solex. Water is injected at the end of combustion to cool the gas and increase the pressure. The main issue to be used in daily driving cars is the rust. It is also possible to inject by ultrasound pulverisator with precise droplets size so that the gas mixture first ignites, then vaporizer the water at high pressure and temperature.

I owned a Honda crf 250l for 2 years and it was the last bike i ever owned. It was also my favorite motorcycle fun to ride on and off road. It could go anywhere depending on my riding skill, was super reliable and had zero problems with the engine, maitenance was super easy and quick, it was very good on fuel average 3l per 100km, the foot peg position made it super comfortable to ride long distances without stopping since i could easily stand up while riding on the highway, i can ride 750km in one day on that bike with no problems and very few rest stops. for a commuter, off roader, or any long distance riding it is the best bike for the price in my humblest of opinions. This bike would make a great super moto as well.
