Despite having four cylinder banks, the INNengine (depending on its configuration) actually has eight pistons. This is because the engine is an opposed-piston motor, meaning that each piston’s ...

A piston engine can suck in its own air and then compress it 10-20x (gas vs diesel, to the nearest multiple of ten) with plenty of leftover energy after the fuel is burned to drive the crank or an ...

The engine you see here has three opposed-piston engines in a chain, forming a triangle. This setup made 3,700 hp when turbocharged. A much simpler bank of six cylinders (12 pistons) could power ...

Ferrari has filed a patent for an engine with pill-shaped pistons, a radical departure from traditional circular piston designs.While Honda famously experimented with oval pistons in the late ...
