Horsepower and torque are all about cylinder pressure. Compression ratio, cam timing, cylinder head flow, and all the rest of the goodies that go into an engine aren't worth much if what enters the ...

The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

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 ...

Torque it, stretch it, compress it--these are just a few of the exercises that engine builders encounter when assembling a high-performance engine. The process of building a bullet requires the skills ...

Automobile engines have undergone tons of changes over the years, primarily to make them more efficient. For the most part though, engine changes result from a string of iterative improvements on ...

This paper explores the feasibility of using in-cylinder pressure-based variables to predict gaseous exhaust emissions levels from a Navistar T444 direct injection die sel engine through the use of ...

Two liters: that's how much water is in an average bottle you use to quench your thirst. It's also the volume displacement of one of the most amazing automotive engines that can completely quench a ...
