Seriously good breakdown of the basic function and automation of an engine.
A fantastic visual learning aid.

The explanation of how a 4-stroke engine works are very clear and easy to understand. The model looks terrific and it is very satisfying to watch the pistons move up and down. To make this app better and more interesting, add more types of engines like for example, V6, V8, and an I6. Also, add a tachometer for RPM to give a representation of how fast an engine really spins. An explanation of more in-depth into an engine like bore • stroke and displacement. Also, explain the types of camshafts there are like for example, SOHC and DOHC and valves. Maybe just to polish it up, improve the graphics quality.

Very good app with no ads!

Really good, great representation of the whole car. I’d like to see though at least the name of the part I click or something like that. Still, great animations, free, with no ads!
