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, ...

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?

Since the invention of one of the earliest practical cars, the Motorwagen, over a century ago, most vehicles have relied on internal combustion engines. This technology combines fuel and air to ...

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 ...

You're at the point in your project where it's time to start building the engine for your car. You're looking online to see what pistons and rebuild kits are available, but the first thing you find ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

The aviation industry is experiencing significant innovation in aircraft propulsion, with new technologies emerging in both piston and turbine engines alongside ongoing development of alternative ...

I have a 1984 CJ-7 with the 258 in it. I put a Howell TBI on it with a Davis Unified ignition on a fresh rebuilt motor. After 800 miles the number-6 piston melted, and that required another 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 ...

From a new V3 Honda engine to Toyota’s latest Hilux, these are the biggest stories in car news today.
