Bore and stroke are important measurements when it comes to calculating an engines displacement, and the kind of performance an engine offers.

Movement of the piston creates a pressure drop across this window. In fact, the relationship between piston movement and valve movement can affect net cylinder filling (volumetric efficiency or VE).

A “boxer” engine is one with cylinders positioned horizontally instead of vertically — the latter configuration found in inline and V-type engines — and the pistons move in the opposite direction from ...

With the improvement of the steam engine (steam engine) by Wat, the industrial revolution occurred in the world. Although it is a steam engine which became to be utilized as a power source of various ...

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

Researchers have developed a new way to design pistons that replaces their conventional rigid elements with a mechanism using compressible structures inside a membrane made of soft materials. The ...

What is a rotary engine? In simple (verging on simplistic) terms, it’s an engine with one or more rotors that rotate – go figure – instead of pistons that reciprocate. The basic principles of internal ...
