When you're at an airport and see propeller aircraft, you likely think it is powered by a piston engine. This is usually true among smaller planes, like the Cessa 172 Skyhawk and the Piper Archer, or ...

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 ...

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 ...

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'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 ...

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

Pistons are an engine-building element we like to brag about, but you won't catch many of us boasting about having cast pistons. Cast pistons are for wimps. Many of us like to talk up hypereutectic ...

While there have been many unusual engine designs over the years, there haven't been many advancements involving the inner workings of the piston engine, except for higher-quality components, since ...

The opposed-piston engine has been around for over 100 years and is more efficient in almost every way. The engine has no traditional valves, cams, or camshafts, and no head, so it’s simpler and ...
