4 stroke to 2 stroke Lada engine conversion

This has been done on YT apparently, but none of those engines were for a car as far as we could tell.

you are correct in your thinking, the problem is the crankcase. i am a 2-stroke motorcycle mechanic and i think the problem is that your engine doesn't have transfer ports to get the mixture from the crankcase to the cylinder. each con rod needs its own sealed chamber with transfer tunnels and ports. hope this gives you something to work with and look forward to seeing it run, keep up the great work and ideas.

Please do not give up on this. I really want to see you guys. Sorry I really wanna have you guys see this one through. I would love to watch it. Thank you.

I want to see an engine that has cylinders 1 and 3 petrol, and cylinders 2 and 4 diesel... make some strange hybrid engine thing

[kevinpiper]

Mechanic here, with lots of experience with 2 strokes including diesel 2 strokes. You need to introduce forced induction to your engine somehow in order to get the gases moving and allow this to run, you've inspired me don't stop

[GroovesAndLands]

In my opinion - shoulda attempted the Detroit Diesel 2-cycle approach. Keep the intake ports as is - but use the original exhaust valves rather than making ports. This way you don't need to keep the individual cylinders sealed off in the bottom end. However, this approach *does* require a supercharger/blower that can actively push fresh air into the cylinder(s). It'll also require long-skirted pistons that cover the intake ports when piston is @ TDC, else the blower will pressurize the crankcase. Detroits actually have piston rings at the bottom of the skirt, to prevent this. It's worth mentioning that cam speed will need to be 1:1 with crank speed.

Nice try, though.

Is this the single most ambitious channel on YouTube? From creating straight 6s out of a 4cylinder, converting a gas to diesel, now a two stroke? This is insane.

Been watching this channel almost since it started and I'm always amazed at the sheer hard work that's put in to every project, even when it was just Vlad in a tiny lock-up garage

[madmod]

You guys are straight up engineers, or mad scientists. I love it either way!!

[anthonybielobockie]

Without crankcase pressure forcing fuel + air mix into the cyls, you'll need to add a super charger like they do on the old Detroit Diesels. Two strokes don't "suck" like 4 stroke on the intake stroke, they need a form of forced induction via crankcase pressure or an external blower. You'll get this to run!

[GHOOGLEMALE]

Great engineering and fabrication - you guys go to enormous lengths to do these projects. Respect!

[ILOVEBACONBOY]

I love this channel no click bait no bs just awesome experiments with talented guys!

[coldwarmotors]

I love this project! Please keep at it and make that 2 stroke Lada engine work! All the best from Canada...

[battleaxefabandmachine]

You should have done it like Detroit diesel did in their 2 stroke line. Use a blower to feed air and in this case, air and fuel. You would need a longer piston skirt to block off the intake ports while piston is moving up to prevent fuel/air from entering crankcase.

This was brilliant, i'm really looking forward to part 2 of this. I know you'll get it running eventually.

[lucasdiniz]

The resonance created in the exhaust of a two-stroke engine is one of the most important parts of its operation, because it does not have valves to maintain compression.

[Dbeattie]

I really want to see you guys pull this one off anything with a two stroke is so cool to me!

[coolwheels]

Even though it didn't really run, you did get it to fire. I think this was one of your best endeavors! It takes quite a bit of knowledge and creativity to accomplish this!

[i.c.e-addiction]

Exhaust is a major key factor to a 2 stroke. It needs an expansion chamber, this helps keep the air/fuel inside the cylinder.

[robinpage]

Keep the factory head, with the valves, but change the timing gear and cam lobes to run a two stroke timing diagram. That is, make it a valved two stroke.

[yucannthahvitt]

Two stroke piston rings are often pinned in place to keep them from rotating until the ends catch in the ports, in addition to the other problems
