The piston compresses the air

When it explodes press the piston

Then the piston will be moving

Put a flame under it, the piston moves up.

What is a piston? Well, that can't be explained.

That's the piston that was fired out of the floor.

The piston does not come into contact with the cylinder cover.

Take it off the flame and pour water on it, or let it cool down, the piston moves down.

The power of the explosion is exerted on a piston... and through connecting rod and crankshaft... through transmission thence to rear wheels

The simplest heat engine, or hot air engine, of all time would be this take a box, a steel canister, with a piston.
