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?

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, ...

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 ...

Remarkable innovations have been made to automotive technology since Karl Benz introduced the world to the "Motorwagen" in 1866 and Henry Ford gave rise to the American auto industry with the Model T ...

LiquidPiston says its new XTS-210 solves the efficiency, lubrication and fuel type issues of Wankel rotary engines. This supercharged, liquid-cooled two-stroke claims 5X the power of an equivalent ...

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.

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...
