Engines have remained fairly true to form over the years without a lot of unusual changes, but a new Ferrari design could ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the ...

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 ...

The candle that burns twice as bright burns half as long; we all know that. However, some of the newest engine designs are ...

The team at Garage 54 replace aluminum pistons inside of an engine with custom-made plastic pistons. The engine, surprisingly, runs for longer than it has any right to run. Garage 54 specializes in ...

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?

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 ...

A single atom inside of a reflective cavity could be enough to drive a piston in a tiny, quantum version of an engine. The essential feature of any engine is that it converts heat into work, which can ...

Cleaning up diesel emissions is one of the hurdles that must be cleared before diesel can become an accepted power mode in the United States, and a researcher in Maryland believes redesigned pistons ...

Not pretty, but we’ve done worse ourselves. By 12 minutes in, we were worried it wasn’t going to work again, but it did work although it wasn’t terribly reliable to start. Still, when it worked, it ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...
