Performance Hydrogen Engine: Part 1 - The Block

[@vostock0998]

love the little 2 stroke motorised bike engine in the background. I'm a huge enthusiast. Built one last year that revs to 11krpm. Balanced crank, ported crankcase and cylinder, expansion pipe, the whole bejangle.

[@Hydrogenguys]

That’s awesome!! I do love 2 stroke power haha

[@bradywinslow870]

Your channel and work remind me that people are working on a better future and it give me hope. As a young person I thank you for all you do

[@tarstarkusz]

12:36 You really should use a torque wrench when installing the connection rod.(you were using a regular wrench and you didn't show it being torqued) You really want the right clearance between the journals. If you did that in the first build, it could be your problem.

[@infectedmushroom7544]

Looks like you did a really thorough job with building that engine. I can't wait to see it running:)

[@tarstarkusz]

Did you polish the piston? Also, you didn't show if you torqued the conrod. What you did show of tightening it down was with a regular wrench. This part really needs to be properly torqued to spec. I know a lot of people bellyache about torquing fasteners. But this ain't like that. The torque spec for this is what controls the clearance between the surfaces. Not getting this right, at least ball-parked near the right spec can easily wreck the engine, especially without proper bearing surfaces used in this application. Otherwise a very nice job. Good video.

[@boone7777777777]

Have you ever heard of the Napier deltic? I designed something kinda inspired by that. Its only 2 vertically opposed cylinders timed together, but I plan on using hydrogen like yourself.

12:12 I had preferred some "upgrade" of the little finger to some kind of spoon-shape for splashing more oil to the cylinder walls.

[@iamawesome69]

everything getting interesting !

[@user-ts1fp4nm9y]

The connecting rod has no bearings?? Great video!!

[@cursetrynd461]

nice job, lets make a v8 from that

[@Hydrogenguys]

That would be the dream

[@ProjectLMZ]

This is super cool! I’m building a homemade engine, is there anything I should look out for if I try to run it on hydrogen? I would make an electrolysis generator, so I would be feeding it hydrogen and oxygen, is there anything particular I should keep an eye out for while running on hydrogen and oxygen? Thank you!!

[@Hydrogenguys]

Make sure the engine is healthy, with good valves and valve seats. And set the ignition timing to TDC. That’s the minimum needed for hydrogen really, if you can get any upgraded parts for the engine internals that deal with heat better that would be beneficial, also a stainless steel high flow exhaust would stop rust in the exhaust. I only really work with pure hydrogen, not hydrogen oxygen pre-mix (HHO) so sadly can’t help there. Thankyou for the comment :)

[@shaynegadsden]

Do mess with hho and engines you get a bang you won't like

[@u.e.u.e.]

Don't forget a high quality oil with a bit higher viscosity than before and ceramic additive! Could you ask someone if PAO or ester based oil will withstand the hydrogen best?

[@RollinMyOwn]

You could bench machine the head with sand paper on a perfectly smooth table top as long as you keep flat itll work

[@Hydrogenguys]

Thankyou for the suggestion

[@IntenseGrid]

I am wondering what that swing weight is for on the cam gear.

[@Hydrogenguys]

It’s to reduce compression when hand starting the engine, the weight swings out once the engine is running

[@b-mice69]

Nicely done , but if you remove the governor why than leave the sprocket on the crankshaft ? Its of no use so only extra weight . Please install heavy duty valve springs because the original (honda) ones will NOT close the valves properly above 5200 rpm wich results in broken valve stem . If you modify the original cilinderhead by a good porting job on the inlet side will give a great response an a boost in performance . There is room for bigger valves . Back in the nineties honda had a lightweight alloy flywheel this wiil result in a much better pick-up in revs . An the last thing i'm a bit worried about is that you've blocked of the crankcase by removing the governorarm , so crankcase breathing is only done by the valvecover ? This will stress de oilseal on the "transmission " side . How do i now? I worked on a indoor go- kart track for 7,5 years so a honda gx200 was the engine that powered these go-karts 😊 alltough its bin twenty years since , good luck with your project

[@Hydrogenguys]

Nice information, cheers. Crank case vent will be on top of the crank case, I only blocked off the flywheel side hole. The engine will eventually have a lightened flywheel and high compression cylinder head with stiffer valve springs. Next video will be all about the cylinder head including porting. Thanks for the comment and info, much appreciated

[@tarstarkusz]

Isn't this going on a generator? They are generally governed to around 3600 RPM. If so, it will never see 5200rpm. I do think he said he may eventually use it in a go kart, but it did come off a generator. Presumably, he will put it back on. I don't think he torqued the conrod. That is one part that really should be torqued to spec. This might have been the problem for the last build.

[@Emilijano249]

what sparkplug were you running? For Hydrogen, the best bet is to run the coldest possible plug, something like an ngk br10es. With ngk plugs the higher the number the colder the plug. You could also try running an iridium plug like the ngk bpr10eix.

[@Hydrogenguys]

100%, I have ordered a cold running plug. Next video will be all about the cylinder head, after that it will be all about ignition timing, I will cover the spark plug in that video. Thanks for the comment :)

[@RIPPERTON]

Should have modified the conrod big end cap for increased oil flow.

[@Hydrogenguys]

Thanks for the tip. The plan is to change the Conrod for a billet one before pushing the engine to the limit

[@RIPPERTON]

@@Hydrogenguys I thought that blade had a hole in the end of it and a gallery that fed oil up to the bigend when it cut through the oil in the sump. Not sure now, cant see any hole.

[@Hydrogenguys]

@@RIPPERTONyeah the standard Conrod doesn’t have the hole, upgraded ones do. Hopefully that would help solve the lubrication issue along with frequent oil changes

[@FURNACE_YGO]

does it have a crank case vent for any water that might work its way down?

[@Dannyt1997]

Would a hydrogen engine work well in a powered kayak or boat?

[@Hydrogenguys]

Why not, hydrogen combustion race boat would be awesome

[@Dannyt1997]

@@Hydrogenguys any sort of hydrogen race series would be ace

[@Hydrogenguys]

@@Dannyt1997sports would be the best use for hydrogen combustion. Keeps the combustion engine alive whilst keeping the high end engineering what’s involved with combustion engines. Like formula 1 for example. Plus hydrogen needs bigger displacement and forced induction to keep up with petrol, would be sick to see v8 and v12 back in action.

[@MichaelMcFearin]

Shouldn’t the ring gap be open a little more with the increase in compression?

[@johnbelwell2461]

No, it will create blow by with the added compression, you only increase the piston ring gap to add up to expansion clearances for performance engines where every bit is calculated for the application including cylinder wall to piston clearance and piston diameter, or when if the ring is meant for multiple different applications and there is a known suggestion to piston ring gap for each one.

[@IntenseGrid]

Also, why did you drill the holes?

[@Hydrogenguys]

After removing the governor there are holes in the engine block, by drilling and taping these holes I can plug them up.

[@philipfreeman72]

I would start with a diesel , they are better / stronger built . Also better able to deal with moisture .

[@RollinMyOwn]

Honda gx160 head will bolt right on and you loose if i remember right like 4 cm thats how my 212 is running

[@Hydrogenguys]

Nice one, in the latest episode I installed a 14cc cylinder head. Not sure that base engine that was from.

[@miketheis53]

Question- Do you still have your old oil? Probably not, but if you did, would you measure its PH? Also, about how many hours were on the old oil?

[@miketheis53]

The reason I ask is because due to the accumulation of blow by of the rings the oils may have gotten slightly acidic due to the hydrogen. I am interested in experimenting with hydrogen also.

[@Hydrogenguys]

It’s a good point, sadly yeah the oil has gone, but the issue is definitely caused by piston ring blow by, will aim to get them gapless rings in the near future

[@philoffhistree6700]

do they not have connecting rod bearings should use an engine that has them as would last better

[@CASHSEC]

Cheap nasty way to save costs at the expense of the consumer.

[@Firby1988]

Some better oil ! 🙂

[@davidepperson2376]

I’m very interested in hydrogen engines, but I can’t seem to find the answer to one question: does anyone know if they behave more like a gasoline engine or if they have the torque of a diesel?

[@kenwheeler6150]

Splash feed for the big end is not good enough for what you plan for this engine. If you can’t fit an oil pump then at least drill th dipper arm so that it can force oil to the big end bearing

[@Hydrogenguys]

Yeah definitely needs an upgrade, taking this one slow so we can learn at the same time, instead of changing everything at once, I have seen a billet con rod with a hole in the dipper arm, will certainly install one of them before pushing big power

[@jefffarmer5785]

[@annpeerkat2020]

did grandpa only have one nugget?

[@oscarolander7455]

Engine design without an oilpump will not last long whatever you do to it. I told you this in the last video.

[@Hydrogenguys]

I agree, thanks for the recommendation, I believe it’s important to find a good oil to use with the standard parts first, test the duration, then improve upon with a pump. The plan is to build this engine with ‘off the shelf’ parts first. Test the limits and power output with hydrogen, then Look into adding an oil pump, filter, and forced induction. To max out the engine. Hopefully this time next year we will have a monster of a 200cc engine :)

[@oscarolander7455]

@@Hydrogenguys I assume this is not an genuine Honda from the beginning and now you replace parts with Honda parts? Check the rod bearing clearance, I believe is quite large on this engines, get it right. I don't believe there's any easy way to add an oil pump to this engines design. Keep the rpm and load down to make it last longer. An genuine Honda has pretty good lifespan, but they keep the rpm and power output down.

[@aceaaron19]

​@Hydrogenguys whatever oul you use, make sure it has plenty of ZDDP and phosphorus. Lucas hot rod oil would be a good one.

[@RollinMyOwn]

This style of little motor has ran for years without a oil pump. Just keep the oil changed.

[@tizianocastro38]

The problem of hydrogen is highly corrosive… It will run but… piston, cylinder etc will go to the dump after a bit of time

[@Hydrogenguys]

Managed to get 2 years out of the cylinder walls so far. Only real damage was caused by the oil contamination, easy fix really. You can see it in the previous video. Thanks for the comment :)

[@STYX-a-Lot]

Take a straight tube, and put 2 pistons in it. One is launched forward to slam into the back of the second one. A charge is compressed between them to HCCI. Both are on a mechanical diode so that they move forward only, and never backwards. The second one doesn’t move forward because in a circle geometry it is connected to the output shaft of the engine, which has to move the car. But in this linear form, it would, of course, just simply move forward, and the charge would not be compressed. I so desperately, wanna move onto the next stage of the engine design, but I have to repeat myself several times in an order to be completely thorough. So, now imagine that instead of just two pistons in a straight tube, there are several. Now you can see that the momentum of the first piston is passed into the second piston, and so on, and so on, and the speed of the final piston is exponentially fast. The first one hits the second one, and it is going twice as fast as the first one, the third one is going even faster, and the fourth and the fifth and so on. This is very important to understand because instead of a straight tube, we will ultimately be using only 4 Pistons that travel in a circle geometry, torus, or donut shape, And it will be equal to a free spinning wheel. It is beyond words and infinitely difficult to explain how the pistons and their arms are assembled into the "one piece" donut shaped housing, so I will explain this once we are face to face. It is meta-genius in a time that viable solutions are mandate. This may seem counterintuitive at first because it will seem like the Pistons have to stop and start over and over, but this is not what is happening. Yes, they are stopping and starting, but there is an air spring between them…, which "is" the charge. It is important that you grasp this, but the momentum of the preceding set of pistons is "fully." Passed on to the succeeding set of pistons, which are connected to the output shaft. In a crankshaft engine, the connecting rod eventually breaks with higher RPMs. In a crankshaft engine it is impossible to achieve HCCI because HCCI would have to occur at top dead center, and none of the combustion’s force would be turned into torque. It would merely try to compress the connecting rod. we literally have to drop the entire concept of a crankshaft. I call it direct torque when a piston travels directly around the output shaft. There are no oblique crankshaft angles to contend with. So, let’s proceed to the actual working design where the pistons travel in a circle. Imagine two pistons across from each other, following each other around in a circle pattern. There is an arm between the two, and the output shaft is in the center of that arm. So, imagine a rubber mallet, and at the end of the wooden handle, it butts up to the end of another 2 headed rubber mallet hammer. One stick handle with a 2 headed piston on each end. The middle of the wooden handle that runs between the 2 rubber mallet heads has the perpendicular output shaft connected to it. Everything is made of metal, and not rubber or wood. This merely describes the shape of the components. So, inside of a hollow donut shaped housing, the first set of pistons, slams into the back of the other set of pistons compressing a charge to HCCI. both sets are on a mechanical diode, so they move one direction, but not the other. You will "not" figure out how the valves work, so don’t waste your time trying. I will have to reveal that when we are face to face. They are completely self actuated, and don’t require mechanical linkage. No valve trains. They are gas operated by trapping a very small portion of the combustion’s force, and as the piston travels along it’s stroke, internal pressure decreases, and the trapped portion of pressure overrides the pressure in the cylinder, and pushes the valve open at precisely the right time. It is done this way because under different engine loads and varying RPMs the pressures, of course deviate. It may sound complicated, but it is extremely simple, and like I say, I would have to show you when we are face-to-face. Now, we have to stop and consider that a hydrogen combustion is 10 times faster than the propagating flame of a gasoline combustion. This engine design is capable of 30 or 40,000 RPMs before it can fly apart due to centripetal force. it will reach these RPMs almost instantly because of the exponential gain in RPMs that I mentioned in the beginning of this presentation. The forward momentum of the preceding piston is passed on to the succeeding set. The shape of this engine is very compact, and just so happens to be the shape of a wheel hub, and therefore fits inside the wheels of a car. I have also designed an infinitely variable, constantly variable, "direct drive" built in transmission that is no bigger than the planetary gear set in an ordinary automatic transmission. This transmission can go from full forward under total engine load to full reverse under total engine load with no damage whatsoever, just by the slide of a shifter. It is unique because you can spool the engine instantly up to 40,000 RPMs, and then engage it to the wheels with no damage to any of the components. It doesn’t have a driveshaft so the frame of the vehicle doesn’t have to be so beefy. Also, The gyroscopic effect will throw the front end of the car downward upon acceleration instead of lifting the front of the vehicle. This gives supreme traction when you want it, and you can break the tires loose at any point when desired for control of the vehicle. Center of balance is lower and far more equally distributed. There is an engine in each wheel of the car for four-wheel-drive if so desired. If it were to run on gasoline it would get 200 miles to a gallon, but hydrogen is free with my approach. The vehicle would be able to accelerate, brake, and corner, faster than the human operator. Now, batteries suck… We all know this. So, to make a car perfectly efficient, we don’t use regenerative breaking that is currently deployed that merely retrieve only 13% because they are trying to recharge batteries which certainly not instant. In the front wheels of the car are electric motors. If the vehicle is going 60 miles an hour and you put on the brakes, the electric motors, capture the energy for stopping the vehicle and put it in super capacitors, not batteries. This will re-launch the vehicle back up to 60 miles an hour for free. That is just an example. If you are going 40 miles an hour and have to stop at a light, the energy is captured, and stored in super capacitors to retrieve 90% to re-launched the vehicle back up to 40 miles an hour no matter how heavy the vehicle is it doesn’t matter if it’s a train, it will do the same. This way, the engines only come on to maintain vehicle speed for absolute efficiency. The vehicle that these engines are in would be able to accelerate, break, and corner faster than the human operator. The cars would be super super light, and super powerful, and super efficient. The way the transmissions work is that they are only a planetary gear set whose annulus is slowed down for higher ratios. It is slowed down by magnets passing wires. That means it generates enormous amounts of electricity to go from neutral to a one for one ration at gradual increments. Where is the electricity sent? To the front electric wheel motors. So, if the back tires break traction, they instantly slow down automatically to grip again. The design is supreme, and can’t be improved upon. Again, hydrogen combustion is 10 times faster than a gasoline combustion, and speed is turned into torque for greater efficiency. My engines don’t need seals so there’s no touching parts except for the bearings that support the weight of the vehicle. They are no load bearings other than the weight of the vehicle. It takes time for gases to escape through a crack, and because these engines are high RPMs, they don’t need seals. They don’t need water to cool them, they don’t need oil to lubricate them. The design is supreme, and hydrogen combustion is the future. There are several ways to get free, hydrogen, and like I mentioned before, it would be ideal to get the hydrogen from electricity from hollow spherical sonic fusion reactor powerplants that I have designed, but that is at least a decade off if I were controlling it. So, a truly easy way to get limitless amounts of free hydrogen would be to choose a spot along the oceanic ridge where tectonic plates separate. Magma is right on the ocean floor so a pipe made of zirconium dioxide would not have to dip into the magma very far for sea water to enter the pipe from the bottom of the ocean with 40,000 psi, and enter the pipe that dips into the lava, and then head straight up for the surface of the ocean. The water would pick up 5000°F continuously, and never reach the surface of the ocean because it would burst into hypersonic steam where it may spin a Pelton turbine far "above" the surface, and create enormous amounts of electricity for electrolysis for a seemingly endless supply of hydrogen fuel for free 😊to be stored on metal hydrides such as that of Plasma Kinetics, so that tritium is made as a free byproduct to be used in fission, and soon, fusion reactors as fuel for even more free renewable energy.
