You need to modify the cam shaft as well. When there are extra strokes the valves will be half open, half closed, and it will take fuel and air in, but will actually expell the fuel when there is a wasted stroke between intake and compression stroke, the valves are opened and will expell fuel and air from the intake. The camshaft needs the lobes moddified so the valves are closed during intake and compression strokes ,and are opened when exhaust stroke is in action. It can be done but camshaft needs a lot of work even if it even can be done. This will make engine have les horspower and will waste a lot of fuel. On paper it can be done but in real life it will be realy hard.

Won't waste any fuel. Intakes and exhausts will be closed during the wasted strokes. It should spin twice as fast and make a slightly lower horsepower. Edit: It's basically just compressing the air, then springing back when the air wants to expand on the wasted strokes, like a diesel trying to engine brake without a Jake brake. Double edit: Actually, it shouldn't be compressing much air since the intake and exhaust will be closed, so either the pressure of vacuum will cause it to slow and lose power or it really won't make much difference in power at all, other than needing to spin at twice the RPM to make it as the original configuration. I'd love to see them actually try this.

If they reduce speed of camshaft twice that mean:on intake stroke valve stay open when piston go down and up, for compresion stroke. That explain why carburator leak fuel on air filter side, piston push back air fuel mixture. On next crankshaft rotation, piston go down and up but all valve is closes so ignition mixture is weak because in previus crankshaft rotation piston push out thrue carburatior most of mixture, that explain poor performane and hard to start engine. I think they need to change camshaft to short time for valve open pozition.

These guys are making a mockery out of most established engineering thought and trends. Incredible working welded crankshafts, now this. I personally was expecting a carburetor to go into orbit and nothing else.

0:16 As an engine machinist, I can tell you that the engine will be less happy. Engines are happy when the temperatures are constant, meaning the piston-to-wall gap is consistent. Having the piston heat and cool continuously will greatly increase the thermal stress it is subjected to, thus giving it a shorter life. Also, the cam lobes need half the separation of the original. Simply spinning the crank twice as fast means the valves are open for multiple entire strokes. Try cutting it up and welding it back together. I mean, you've done it with cranks before lol

This is what I was thinking the entire time I watched it, and I'm astonished that it actually took on under its own power. Had to have just been the magic speed and mixture of air/fuel in the manifolds.

Fantastic you got it to run at all, let alone drive.

koenigsegg uses an 8 stroke engine to pressurize an air tank for the freevalve(camless electropneumatic valves) system. It would be cool if you guys could try to make this 8 stroke pressurize a tank for some air bags or a home made freevalve system like the miata guy.

Make a 3 cylinder engine that is 2 stroke diesel on the front cylinder and 4 stroke gasoline on the middle back two. Using 3 out of 4 cylinders on your Lada engine the crankshaft will already be right. You just need a cam shaft with extra lobes for the 2 stroke cylinder, and an exhaust that works. A flat-plane 3 cylinder effectively firing like a 4 cylinder. Firing order 1-3-1-2. Make that work and then build an in-line 6 engine with the front and rear cylinders 2 stroke. A cross-plane in-line 6 cylinder effectively firing like a 8 cylinder. Firing order 1-5-6-2-1-4-6-3.

You could just halve the ignition timing to do the same thing.

This should sound awesome! Hell YEAH!!

All it needed was a bigger crankshaft sprocket.

4 extra stokes full of non burnt fuel.

You guy's have the best car idea's on KZread.

Thats amazing it ran even idled! Now of course, if we are to be honest, its probably cutting the already modest power output of that Lada in half. Just like a two stroke makes roughly twice as much power as a four stroke, this would make very little power since the combustion is happening so infrequently and the crank is basically coasting for longer in between explosions. I bet theres a use for it in some industrial setting though, and probably is already. Good job as usual boys!

this a real meta episode, where you fuck it up for the sake of fucking it up, cause everything i've ever seen you guys do, you fuck shit up. keep at it fellas!

I believe it needs a special camshaft.

Try a 16 stroke engine next!

As always, great content. I appreciate the translations. I wonder why all the automakers have not thought of this a century ago.

Now make a double action diesel engine ie both top and bottom faces of piston doing power strokes in turn. The crankshaft can be dealt with a double scotch yoke system.

Sergei is super smart

These dudes are awesome!! Been a fan for a while now and they never cease to amaze me!!

i think you forgot about the compression, the valves are closed by default which would cause restrictions when the "wasted stroke" happens which is likely why the starter was having such a hard time. if you had one of the valves open this problem would be somewhat alleviated, if you use the exhausts you will be sucking pollutants back into the engine further contaminating the oil, if you use the intake then you mess with the vacuum/intake physics. best thing would be a "open air" valve but this would require more engine modifications than a single video would cover. maybe multiple videos but it would require much more than just crank/valve ratios. Using only 4 cyl engine this makes it much more difficult since you are moving 3 pistons with a single piston providing the power so this issue would be much more pronounced vs something like a I8 or I6 engine.

Add wasted spark for the wasted stroke

24 volts should be ok as long as you only use 24volts for cranking the engine and when it starts up disconnect one of the 12 volt batteries used to make 24 volts I see people do it all the time

I'm having a bit of trouble with this one. Slowing the camshaft down to half speed (that was half, right?) is going to seriously mess with valve duration. I mean, yes it ran- but what the heck is going on inside that engine?

Ive learned that nothing is impossible in Russia

i love the art on your walls

I am surprised this worked! Well done everyone.

You guys are always doing something interesting! Thanks for the good laughs!!

Y’all guys are pretty awesome. I love watching what y’all do

half the camshaft speed doubles the duration , you need narrower camlobes too

I figured it would have ZERO torque but you guys proved me wrong . lol Great job guys . :)

Great video! You´ll need to re-shape the cam lobes as well. Otherwise, the intake valve will not yet be fully open when the intake stroke ends, but will be fully open at some point during the upwards 'waste' stroke after it. Similarly, the exhaust valve will be fully open during the downwards 'waste' stroke after the upwards exhaust stroke. The engine might run, as you demonstrated, but with great loss of power and wasted fuel too.

Problem is now every stroke lasts twice as long, meaning during an intake stroke the piston goes down and then back up right? So it pushes the air back out

I'm honestly fascinated that you got this to run, on a carburetor no less. With a stock spec camshaft, you double the duration specs which means... Well a lot of things. I doubt it would have real benefit to retrofit something into this, but it is super neat to see that something could, in fact, run this way. And a hell of a conversation topic especially for new mechanics or those in school to learn.

7:40 Engineering Explained parody ;)

Trying to figure this one out hurts my brain ! Good job guys !

I suggested an 8 stroke cycle in a Senior project in 1971. The idea was based on the Eaton/GM 8/6/4 system idea. Rather than shut down a cylinder bank or a set of cylinders until extra power was needed each cylinder was left fallow for 4 cycles (2 revs) before another power cycle begins. This would have an engine from say an 8 cylinder engine to a 4 cylinder. This can now be done with electronics controlling spark and fuel, even valves if necessary. This keeps the cylinders warm for better efficiency. That being better wear, emissions and reduced friction on unpowered cycles. I think this would give around 30% improvement in efficiency. I outlined this in a paper at my university in Valparaiso Indiana. Unfortunately technical and time deficiencies precluded physical modeling. Check with university for any patent issues. Cheers.

do more experimenting and converting engine like this! i like this content 👍👍

Wait, so now that there's a wasted stroke- feed the exhaust gases to it! Like a very advanced EGR

Would have been interesting if it was possible to somehow measure difference in fuel economy.

The issue is, all 4 'strokes' of the engine, in comp comb and ex all have a down and up of the piston, which completely undoes all of the stuff that stroke does

@joey66436

yep was hoping someone had picked up on that. With the cam timing advanced, the intake may open early, but close early, on the down stroke. Same and opposite for the exhaust. Surprised it ran!

These guys are great! They have done some crazy stuff and actually made it work. Their motor made of PVC that actually worked fair with 2 cylinders might fly if they used 8 cylinders. Always enjoy what they come up with.

You should make a 8-valve per cylinder head. For a world record!

@Garage54 - How about a 4 cylinder 'Parallel twin'? ie Mod the crank, cam & timing so that cylinders 1 & 4 fire THEN cylinders 2 & 3 fire. HOW would that feel in driveability/traction/torque? 🤔😏👍 😎🇬🇧

I tell you what Vlad, it's got Sooooooooooooo much torque at the wheels its off the charts. I could see it in the increase/decrease timings of the wheel spin.

I was not expecting that to fire up!

I'm wondering if the original cam timing had a certain degree of advance, like 4 degrees, if it needed advanced to 8 degrees. Also with the ignition timing, if it also needed to be doubled. Like, instead of 5 degrees BTDC, if it needs advanced to 10 degrees BTDC.

always interesting to see what you come up with..

If you use something like Fiat’s Multiair for the valve train and program it right it might work ..

Perfect!

Nice work im trying your changing terminal on dead battery at the moment 👍

Do they have a custom cam shaft on this because simply halving the speed of the camshaft will not do what they want. Normally you have INTAKE valve open, then both valves closed for compression and ignition expansion, then EXHAUST valve open for the final stroke. Even if timed correctly at the beginning, a half speed camshaft will have the intake valve open on both drawing fuel in and the compression, trying to send fuel air mixture back where it came from (hence the carburettor spewing fuel), then you will have two complete crank shaft revolutions with both valves closed, and then the exhaust valve will be open to draw exhaust into the cylinder and blow it straight out again. That's if you avoid damaging the valves if they are open with the cylinder at top dead centre.

at 7:44 I say the extra cycle sucks in one cycle's worth of fuel without any combustion, so that extra fuel is just sitting there waiting, then another cycle's worth of fuel comes again, but it's too much for it to fire properly', and that's what is happening'

A 6-stroke was patented in 1917, and many times since, so no doubt people have tried this before.

Ever thought of how many teeth were on the belt to links in the chain

2 stroke would be nice

Can you post HQ stills of your calculations? I'm an engineering major in a precalc class and I'm extra excited to see the practicality come to life with something I'm close to understanding

Awesome video. What does the bigger cam gear do does it make the camshaft rotate faster or slower?

“We need a 42 tooth sprocket, not a 44.” Proceeds to file two teeth off the sprocket.

It would be interesting for them to grind a camshaft to close the intake much earlier, about 90 deg before BDC to create an Atkinson cycle engine.

I wanted to hear it run clearer
