The mind-bending world of birotary engines - a hybrid of piston and rotary technology that could revolutionize aviation. But ...

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?

Gasoline and diesel engines feature many differences aside from fuel type. Compared to gasoline engines, a diesel is ...

The continuous drive for enhanced efficiency and reliability in modern diesel engines has prompted extensive research into the thermal management of critical components such as pistons. The ...

Most of us consider piston rings little more than a necessary evil. That's probably because grinding rings is a time-consuming chore. And who hasn't accidently ground a gap too large and wasted both ...

If you are a motorhead, an unusual engine will immediately get your attention. Most vehicles today have either an inline or V-shaped configuration, so anything peculiar will immediately stick out. If ...

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 ...
