Two stroke engines don't usually have valves, they just have holes in the cylinder that get covered by the piston when it goes up or down. But I suppose adding the valvetrain makes it more interesting and it wouldn't make sense to have a four stroke air-powered engine.

Wow, thanks so much for your thoughtful comment. I think of this engine as a two stroke engine disguised as a four stroke. It has the valvetrain of a four stroke that we all know and love (or is that just me? 😂) but to run well on airflow is uses a two stroke cycle. I'd like to see more LEGO engines that are two stroke air engines disguised as *two* stroke IC engines! Do you build? Thanks again for sharing the knowledge in the comment section!

That’s awesome! Just wondering though, why do you need to have a non-lego cylinder sleeve? Also, I don’t think it matters that much for aesthetic reasons but I really do think it would run a lot better with a cam-profile that has a longer duration and less lift. Very realistic!
@engine1ear151
7 ай бұрын
Thanks for the thoughtful comment. It has a non-LEGO cylinder sleeve because I tested building the cylinder out of LEGO and there was too much friction for it to run even after break-in. And you nailed it with the cam lobes - this was the first iteration for this engine, made to look realistic and inspired by a LEGO Ideas "working four cylinder engine." When it ran with them, I was delighted and didn't want to change them :D

could u make the gear ratio a 2:1 instead of 1:1 cuz i think it would be even moe realistic but its very realistic and i love this build keep up the good work wit the channel man much love @@engine1ear151
@engine1ear151

@@MatthewBarnes-2023, I like the way you think. Yes, it would add points for realism to have a 2:1 gear ratio. Now let's follow that proposition through to it's conclusion. It would mean we have each valve opening every TWO crank rotations now instead of every ONE. That would leave a full crankshaft rotation (piston upstroke and downstroke) in which the air only gets in or out via gaps between bricks. This engine doesn't have amazing depression (sealing) but it has enough that the upstroke and downstroke mentioned above in the 2:1 ratio scenario would cause a pumping loss that the inertia of the flywheel would simply not overcome. Another way of expressing it is that 2:1 ratio would be making this engine a four-stroke engine, but there is no power stroke from combustion so the stroke normally known as the power stroke in internal combustion would only result in a mechanical loss. I could set up the engine in a 2:1 configuration to show it off with the extra realism, but without a significantly more powerful power stroke, or a design more resembling the four-stroke cycle, it wouldn't run. So I opted for it to run. I'd love to know any ideas you or anyone else has for solving the 2:1 ratio design problem on a LEGO air-powered engine. I've had some myself in the past and haven't yet tested them. Thanks for the comment :D

One is very limited with the shapes of the lego bricks that are available, I know how much time and effort it takes to find and arrange the lego pieces to create the mechanism in such a small space. At first I thought, the torque wrench is a non working display model lol. I am very curious, with what you come up next. The engine you made is sick, never seen before.
