"How it Works" -> "Idk" OP probably

I see no declaration that this is a machine generated site, but the aesthetic is a dead giveaway. The language on the “how it works” page is unmistakably LLM output. As a total novice in engines this site had the potential to educate me, but did the author vet the data at all? If the author doesn’t bother telling me they checked any output on this, what assurance do I have anything is accurate on the site at all? If…

The aesthetic is what I get any time I ask for something UI-like in Claude. But gosh darn it I like the look.

If you're looking for a carefully crafted/written work to explain internal combustion engines, look no further than this one https://ciechanow.ski/internal-combustion-engine/ (the Mechanical Watch article from the same author was featured on HN a while ago).

I wish he was still making posts.

So if I set the animation speed to 1:1 and set the RPM to 3000, that's what it would look like inside the engine when I'm ready to shift gears? Seems WAY faster than what I expected in real life

3000? Here I am wishing there was some Wankel Rotary representation and you're shifting at 3000? What are you driving, a Peterbilt?

Calling this AI slop would be generous. If we made a list of the things wrong with it we would be here all day. Nothing has an effect on redline RPM, you can create compression and turbo combos that would instantly grenade an engine, the preset “super car” has 200hp?

The only thing it illustrates is the authors lack of understanding.

I don't understand how the throttle and RPM can be modified independently. Surely the RPM depends on the throttle?

When you press the gas pedal in your car down (which used to just be a cable to the throttle body), does your car instantaneously increase in speed to match the pedal position?

All you're doing is letting more air in - the RPM is a function of the power the engine generates; more fuel and air than is currently needed for the current load at the current speed = increasing RPMs.

If you put the clutch in, a little blip of the gas is all that's needed to get the RPM quite high very quickly. The moment there's load on there, the same blip will not do very much at all.

@AngeTheGreat on youtube is worth mentioning here, I think.

He has a whole series on building out engine simulators of various types, and even published a Steam game for steam engine simulation.

His work is notable because he leans heavily into generating sound directly from the simulations.
