Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

You might overlook the end gaps of piston rings in your car. They shouldn't be taken so lightly, though, as they actually play a vital role in your engine.
