It's important to keep in mind that the combustion process occurs in a very brief period of time. Due to a variety of conditions that include mixture density, homogeneity, temperature, fuel ...

The film discusses various types of engines that utilize heat energy for operation. It explains steam engines, which are reciprocating external combustion engines, and compares them to internal ...

Aircraft engine maker Pratt & Whitney showed a video last week about the XA103 adaptive cycle engine that also pictured what might have been the F-47.

Adaptive cycle engines are specially designed to alternate between efficiency and raw power—extending an aircraft’s range without compromising on speed during engagements. The modern fighter jet is ...

The X-Engine technology used in the XTS-210 is a direct drive rotary approach that can be viewed as an "inverted" Wankel engine. It has a trochoidal rotor with a three-lobed housing, but it utilizes a ...

The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

Years ago, the choice was clear: When it came to 2 stroke vs 4 stroke outboard motors, 2 stroke won every time. Two stroke motors offered a better power-to-weight ratio, were cheaper to manufacture, ...
