Newest wrinkle in rocketry is the “plug nozzle” engine. In the conventional rocket engine, fuel is burned in a roughly spherical combustion chamber, and turns into hot, high-pressure gas. To keep the ...

Virtually all current production-based cylinder heads incorporate a cross-flow design with intake ports (Photo B) located on one side of the head and exhaust ports (Photo C) on the opposite side. Some ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Internal combustion engines are literally the engines of the modern world. Without the invention of these genius mechanical creations, our world would be markedly different and the pace of life would ...

A vital piece of gas engines, combustors -- the chambers in which the combustion powering the engine occurs -- have the problem of breaking down due to fatal high-frequency oscillations during the ...

Though they're the only engines officially named after their hemispherical combustion chambers, Chrysler's legendary V8s aren't the only mass-produced automotive engines to feature this technology.
