I agree it looks a little confusing.

Doesn't look confusing at all. There's just no explanation attached so that might make it confusing

So you're saying for someone who isn't knowledgeable on the subject, it's confusing?

Intake - piston travels down to pull in air/fuel mix; compression - piston travels up to compress mix; power - mixture ignites, forcing piston down; exhaust - piston travels up to force out exhaust; process starts over.
Exhaust cycle for the valve timing seems a little bit off, but it’s close.

Lol it's way off.
johnson_united t1_iwgbhre wrote
You’re right, I slowed it down. Exhaust is opening at BDC, usually it’s cycle is 100-5 degrees BTDC.

It is just a diagram after all, not a precision-built machine, so I don’t think we can expect much in terms of ultra-realism. There are other things wrong with it, too, like no valve overlap, and the firing order has a noticeable lag between cylinders 1 and 3, makes for a very unbalanced engine.

It would be easier to make it correct in a diagram vs real life.
Aggrador t1_iwgso6i wrote
It would be easier, but it’s not super critical either. This gives you a general idea of how a 4-cycle engine works. All I was trying to say is you could pick it apart and find everything wrong with it, but at the end of the day, it is just a diagram. But yeah, i agree, it would be easier to make in a diagram vs real life.

Blue valve opens, gas gets injected, piston is pushed back up, gas compresses, spark, boom. Red valve opens and smoke exists. Note how the piston does 4 up/downs in a cycle. Only 1 of those steps is powered by gas dirextly. The 3 other steps are powered by the movement of another piston.
The real beauty in there is the cam shaft IMO. The green things moving the valve. They have to be perfectly configured andnthe gear ration needs to be precise otherwise the valve wouldn't open at the right time.
This is not my expertise though ... I could be wrong

"Gas" is not injected. Air is sucked in because the piston moves down. Fuel could be injected either directly or just before the blue valve.

Explosion makes piston thingy move, which turns other thingy and makes wheels turn.
