Taking an engine compression test is sort of like checking your car's blood pressure. It's a quick and painless procedure that can reveal hidden issues.

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 pickup trucks sold today have internal combustion engines. Passenger vehicles are powered by two main types of engines: compression, aka diesel, and spark ignition, aka gasoline. Besides the type ...

What is one of the most critical variables you can set when building an engine? That could be a long debate, but compression is certainly one of the main ones. It dictates not only how much power you ...

Strictly defined, compression ratio is the total volume above the piston at bottom dead center (BDC), divided by the total volume above the piston at top dead center (TDC). First, let's look at the ...

Infiniti introduced the world's first variable compression-ratio engine, a technology it claims to have been working on for two decades, at the 2017 Los Angeles Auto Show. A variable compression-ratio ...

There is no shortage of people around the world today who seem pretty certain that the days of the internal combustion engine (ICE) as the primary form of propulsion for transportation are effectively ...
