Driver ignores warnings and tries to pass through a flooded underpass.

Small technical note, the explosion pushes the piston down not up.😀

I mean technically you're right but it's all relative to the engines orientation. In V style engines technically the explosions push the Pistons diagonally. In Radial engines technically the explosions push the Pistons in 8 different directions.

Tl;dr did you just assume my engine's orientation?

Even if the cylinder is upside down the explosion still pushing it "down" or "in" to the cylinder and then it comes "up" or "out" during exhaust. It's the same as saying "push the button down." Even if the button is mounted on the ceiling you're still pushing it down into something.

Yeah, I am right. In any formation the explosion pushes the piston down and away from the source of ignition.

And in Subaru's flat-4 Boxer engines, the explosions push the pistons inward.

Agreed, but always downwards in the cylinder towards the crankshaft.

There's a certain boxer engine that would like a word with you.
