Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

Most engines generate power from an internal combustion system. On the basic level, these engines work by compressing fuel and air into a tight space. Within the cylinders of an engine, pistons pump ...

With every passing day the Mule provides opportunities beyond our original expectations. Since the 467ci engine belongs to HPP editor Tom DeMauro, it is at our beck and call. This affords HPP the ...

Time was when a valve job was done with some valve-grinding compound and a vacuum cup on a stick. But no more. Today's high performance engines require the same machining precision in the valves that ...

The L83 5.3 liter: One of GM's most widely used engines, see what plagues this and other V8 engines that come in some of our ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

All of this rotates on a fixed ring gear connected directly to the output shaft. It uses a valve disk that also rotates to complete a four-stroke cycle of intake, compression, combustion, and exhaust ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...
