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 ...

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 ...

In this video, you'll see the different types of engines and propulsion systems used for aircraft, my favorite ones: Turbojet ...

Unless you rebuilding an engine with little to no budget you're going to upgrade to aluminum forged pistons. Besides being stronger than cast pistons, the lighter aluminum cuts parasitic power loss.

A partnership between Diamond Aircraft and the Austrian government is developing options to power general aviation aircraft with liquid hydrogen. A team from Austro Engine and Bosch General Aviation ...

Ferrari is exploring a groundbreaking approach to the internal combustion engine, as revealed by a recent European patent filing. Departing from the industry-standard round pistons, this new design ...

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 ...
