The story of how Honda developed an oval-piston race engine that ultimately failed but still made history along the way.

In the 1930s, Italy set out to reclaim national prestige through speed. The Macchi Castoldi MC72 seaplane, powered by a ...

Since the development of the internal combustion engine, humanity has long pursued the common goal to make them run as fast as possible. And whether it's gasoline-powered engineering marvels like ...

In a conventional application, there are three rings per piston. The top ring is called the compression ring. Its purpose is to seal the combustion gas pressure, transfer heat from the piston to 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 ...

Many don't realize that pistons can make power...or not if you make the wrong decisions. In most cases more compression means more power. What are two of the main factors that determine the ...

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 ...

Gasoline and diesel engines feature many differences aside from fuel type. Compared to gasoline engines, a diesel is typically a lower-revving, torquier design, hence why it's often preferred over ...
