I drove a Ford F250 6.9 diesel to college for 3 years on WMO. I put about 30K miles on it with used oil. I did try the 80/20 with UR gas. I ended up using a blend of 20 percent diesel with motor oil. In the hotter months and when I was broke I would run straight WMO. It had dual tanks and I kept one tank with pure diesel for start up and shut down. It was an hour drive each way to campus, so plenty of time to get the engine warm before switch to straight motor oil. Love the experiments!

When I worked as an auto shop machinist (back in the 70’s), we would modify the head(s) to run on propane. A local conversion shop would send us the heads and we would mill out all the valve seats and replace them with Stellite seats along with Stellite valves. We would bore the valve guides and insert brass sleeves and then cut down the boss and press on Teflon valve seals. Without these mods, the oil moving down the valve stems would mix with the propane and become a serious grinding compound that would wallow out the valve guides and valve seats. If run to long it would destroy the head(s) and you would need a new head(s) and the modifications.

[@espenschjelderup426]

Propane burns much hotter than gasoline, overheating the valve seats. It's the same thing happening in a head that was made for running leaded fuel when you run unleaded. I had this happening to my daily last year because I'm running it on a LPG blend that's pure propane. In warmer countrys than where I live they run a propane/butane blend that burns much colder than pure propane, and because of the lower EGT they don't have as much a problem with valve seats.

[@VwDrake]

I have some bonus information about propane conversions, that was my first gig as a wrench-bender, doing propane conversions. Back in that era, the incoming fuel charge was acting as a thermal sink for the valves. Semi-atomized fuel vapour getting sucked in the intake cools the faces of the valves and the valve seats. Especially leaded fuel. Propane is thoroughly vaporized before it gets to the intake, adn just doesn't have the thermal mass that equivalent droplets of gasoline did, so the combustion surface of the head would run hotter than it ever would on gasoline. Especially when guys would do sloppy conversions, and set the system "dry" or lean, trying to get mileage out of the vehicle, the heads/valves/seats/guides take a wicked beating. Same sloppy guys would then set the system "wet" with propane, which would then promptly wash out the rings, and in not too long they were burning oil, and Their oil was turning a weird brownish colour. :) But yeah, especially 70's Gm's would barely make 50,000miles on stock heads running propane, before an overhaul. Although one they were done properly once, with the stellite seats, etc, they were good to go for way longer.

[@earlwheelock7844]

Does the valves have to be solid stelite or can you get away with valves with a stelite hard face welded to seat?? Also I have heard of conversions using stainless steel valves ???.

[@darrenschmitz2712]

On the "detonation" you observed I think there is validity to it. Propane has an octane rating of around 110 which makes it much more difficult to ignite without a spark than diesel fuel. In a diesel engine typically only the leading edge of the fuel/ air mixture cloud radiating out from the injector ignites because it has the proper conditions. Because of this the burn is relatively smooth because the combustion process is draw out without any, (hopefully), high combustion pressure spikes. However, when you add propane when the diesel ignites then the entire volume propane ignites in a short time causing a spike in combustion chamber pressure creating the "knock: you are hearing. This can also occurs with a cold diesel engine when self ignition of the fuel is relatively delayed and more of the fuel / air mixture ignites at once causing knock.

[@clynesnowtail1257]

Yeah Ive read that adding propane has a similar effect to putting in timing on a diesel. Adding too much propane causes the same problems and damage that too much timing does. Your explanation makes sense for why that would be.

@@RNA0ROGER RCCI is usually used for single fuel engines that operate with a lean (low reactivity) homogeneous charge and a seperate injection to create a richer pocket (higher reactivity) that is able to ignite under the given conditions, which the leads either to combustion from that ignition source or to a HCCI like combustion with the charge igniting at multiple spots/everywhere simultaneously due to the raised pressure and temperature from the rich pocket being combusted. This is usually called Bi-fuel. All those terms are often a bit overlapping in certain aspects and sometimes not very well defined.

Hey Jimbo, regarding the propane testing, what you saw was exactly what should have happened. I work at a University and we do alot of dual fuel testing with diesel engines that have port injection of high octane fuels like propane, gasoline, ethanol, methanol, etc. What you saw is exactly what normally happens. The combustion will get alot faster and louder, as it is knocking; which you heard and saw with the lower EGTs. Also when you port inject fuel, some of it will not burn, which is common and which is why you can smell propane in the exhaust. The main reason to run dual fuel engines is that they can have alot less soot and NOx, but they will have more unburned fuel and CO emissions. The brake thermal efficiency is also a bit better due to the faster and louder combustion. Also regarding the carburetor, I think it would be interesting to use it in future for your own dual fuel testing to inject fuels like gasoline, E85, methanol, etc and see how it effects the engine performance.

The propane ignites after the diesel, increasing the peak pressure drastically. This is known as diesel knock. Diesel knock happens when you burn low cetan fuel, which ignites to slow. The fire in the cylinder starts slow and increases in speed drastically, once the temperature in the combustion starts rising with partiale burnt fuel. This usually happens with vegetable oil on direct injected high speed diesels.

That would have been Biodiesel and is a much more refined fuel. You mix a certain amount of KOH or NaOH with ~20 methanol and mix it with veg oil at 125F. That reacts together and glycerine will settle out and leave thinner fuel on the top. If you use it right away, all you have to do is filter it to finish. If you plan on stock piling it, you'll need to wash the soap ions out of the fuel or it will settle out over time and clog filters.

The 'Big Boys' with the 1000hp cummins inline sixes use propane in the same manner gasoline engines use Nitrous Oxide setups, except since a Diesel runs lean, it just adds propane as extra fuel, and since it's a low temperature gas, it has an intercooling effect, resulting in the lower cylinder temps. Instead of using the Arduino to cut fuel when cylinder temps get past a certain point, you could shoot a small amount of propane instead, and cut it off at say, 100*f lower than max, allowing you to have "merge in traffic on the highway" power. It would also allow WOT operation for longer periods of time, by controlling exhaust temps in a way that doesn't cost power.

Excellent! Next time try Hydrogen. You only need 12volts or less at 2amps DC. In a bucket of water put two wires from the power source. The water will break into hydrogen and oxygen. Run the possitive lead into the bucket through a tube vented outside of the bucket. That will keep the hydrogen from being catalyzed (explosive) by it in the bucket after its split. The bubbles that come off the negative wire in the bucket will be pure hydrogen. You can make it with the bucket you used for the water vapor experiment. The amount of hydrogen bubbles can be controlled with a rheostat so that you aren't making more than the engine can "burn". You don't want to flood the garage with hydrogen.

About your water vapour test. There are 3rd party water injection kits that place a spray nozzle inside the intake manifold. Great for reducing intake air temperatures on boosted vehicles. Because of the high heat and fine spraying nozzle, the water vaporizes almost instantly. Additionally you CAN run a water-ethanol mix and get a real boost in performance. Though I don't know how this would pan out in a diesel application hahaha. Just thought you might find that interesting^^ Thanks for the video

It would be interesting to see how water injection would affect fuel economy. Reinstall the carburetor, keep it wired wide open, and hook it up to water instead of fuel. It should do a very nice job of both atomizing the water and metering it so that you don't ingest too much and damage the engine. Best to use distilled water, minerals in the water will turn into particles when the water evaporates in the combustion chamber. I suspect you will see the water injection result in a small savings in diesel, although I'm not really sure how easy it would be to implement this on the car. I've enjoyed this entire series since you started adapting the Kubota engine to the old car. Keep up the good work!

"Propane into the engine" Hank Hill wholeheartedly approves.

[@ChrisDay-sx4lv]

Thrilled to see you trying my suggestion of water injection, and that it works bringing the EGT down. What I would have loved to see is the testing of fuel consumption while using it! BTW you can get ultrasonic foggers with up to 12 heads from the jungle site. You could have also filled the carb you attached up with distilled water! another possibility is using a kettle or steam generator to inject steam.

[@mrjlarsen]

Thanks for a great video. Was disappointed last Sunday no video. 😂 but you made up for it today

[@robotcantina8957]

Sorry! Its been too hot to work in the shop. For the next month or so we will be releasing a video every two weeks.

In my day job, I wrote the control firmware for a company called Innovative Fuel Systems in Edmonton, Canada that injects CNG into PACCAR and Cummins 13 litre diesel engines on semi trucks. As an amount of diesel was removed, an energy-wise equal amount of CNG was injected. The engine runs slow enough that I could do the fuelling calculation in the time between injection events in real time. The whole system works very well, running very clean, without unburned methane in the exhaust, and the oil stays clean for much longer.

[@tommaso_v24]

Really silly Idea, but Marine Diesel Engines are having "Green" Methanol systems (Pure Methanol made from hydrogen as an additional fuel source, not water/meth injection) fitted as a way to reduce emissions. It would be neat to see how your engine runs with an alcohol based fuel being supplied by the carburetor. It would also be neat to see if a carb could act as a traditional water/meth system.

[@oxygenium92]

Propane or lpg systems can be added to a diesel engine and it inproves diesel consumption, adds power and reduces pollution, they are getting more attention in my country (poland) mostly in semi trucks, heavy equipment and farming equipment. I would love seeing you explore this further.

[@bobirving6052]

I had fun AND learned stuff! I think the knock is from the propane lighting as soon as the diesel injects. Propane should have an octane about 150, but this small engine probably has it’s injection advanced due to it’s relatively low fuel pressure.

[@ygorlhano]

looking forward for the videos on that S10!

[@NVclosetmedgrower]

I'm curious, jimbo, what did you do to get rid of the gnomes? Haven't seen them show up with their antics in a long time. Appreciate the videos.

[@robotcantina8957]

They are still around.....

[@randr10]

Could the carburetor be used as a ready-made water or water-meth injection setup? That's pretty cool that it will bolt right up like that.

[@markchapman2585]

Awesome video Jimbo.

[@recyclebills]

A lot of trucking companies used to dispose of waste motor oil by pouring it into the fuel tanks, 11 gallons of waste oil to a 300 gallon fuel tank.

[@JCGver]

You don't want to know how much really nasty chemicals get disposed in a similair fashion by mixing it in the bunker oil for large container ships and such. As the saying goes: ain't no emission testing on international waters.

[@dangrefrath9852]

Very educational. Thanks!

[@schrenk-d]

A note on gas injection. In Australia there is a ... kiind of common after market modification that people sometimes did, which is run a LNG (about 90% Methane in Australia) injection system on their diesel. It does improve power and efficiency, while making the engine burn a little cleaner. However, some systems caused issues with a lot of engines.

[@cullenmiller8170]

Nice video and interesting experiments. I have thought about buying one of those little Diesel engines of the jungle site. I have a brand new 160amp semi alternator sitting on the shelf and figured I could build a cheap generator to charge my RV batteries.

[@robotcantina8957]

Its a tough call, if you have diesel fuel available, then this may be a great engine for your charging rig. Keep in mind a 212cc gasoline Predator actually runs better and makes less noise.

[@SadeXo1]

Propane is a well-known additive to diesel engines in Poland. conservatively replaces approximately 30% of diesel fuel with propane, providing 15% cost savings. It may not be much, but in the case of heavy equipment, where fuel consumption is measured in tons per day, it is a lot. STAG AC is well-known controller for LPG installations in diesel engines.

[@DaveFromColorado]

I am saddened that you've missed another week.. I truly hope everything and everyone is okay!

[@CriticoolHit]

the oil/fuel mixture in motion exposed to atmosphere actually causes the fuel to evaporate quite quickly. 1 hour of this is something to consider when factoring in ratios.

[@dangerousdave5915]

Finally PATREON! Yippeee!

[@DarronBirgenheier]

Great stuff, as always, from the Wizard of Kansas! How about plumbing the regulated output of a large shop air compressor into the engine's intake? Start the engine on ambient air, then switch over with a dual-input, single output air valve to the pressurized source...

[@peterjohn3180]

In the Gardner engine manual it says to filter the used oil after oil change and just add it to fuel tank! I used to get the missfueled fuel tank contents from my local garage after people put petrol in diesel cars, I would mix it with veg oil when veg oil cost 30p a litre, shops are wise to it now so it costs £1.50!

[@billynomates920]

you've got some pretty good ideas of where to measure the temperatures!

[@olivierroy1301]

Awesome! I liked that episode. About the propane injection, I seen somewhere that by injecting propane in a diesel engine it could reduce soot to the point that a diesel particulate filter is no longer needed. If you can reduce combustion temp it will reduce NOX emissions and with the soot reduction it would make it more environmentally friendly. About the water vapors, I'd be curious to see if I can boil water with the exhaust heat. Maybe a setup that would make some kind of flash boiler... A double layer exhaust tube where the water would be preheated and a fined tube making like a flash boiler in the exhaust flow. I like those experiments.

[@cj691]

The propane smell is the odorant they add to it. Propane itself is odorless. Also, the shop vac exhaust also has its motor heat in it, so the exhaust gases not changing temp would makes sense. You would need a charge air cooler or a real supercharger/blower.

[@abegiesbrecht1148]

I enjoyed this. Thank you 😊

[@mattt198654321]

One time when I was a kid, my buddy and I tried supercharging his grandma's buick with a leafblower. It didn't do anything but it sure as heck made a lot of noise.
