Several organizations, encompassing companies, research labs, and academia, have formed the Hydrogen Opposed Piston Engine Working Group, a collaborative forum to advance sustainable transportation ...

Your engine is supposed to vibrate, just a little. But when the shaking gets harder to ignore, there’s probably something wrong.

There’s a large slice of human philosophy predicated on the maxim that if the fundamentals are sound, don’t fiddle around with them – a line of thought given voice in a myriad of different sayings, ...

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, ...

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 ...

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?

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 ...
