Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

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 ...

Billed as the Next Big Thing for the gasoline engine, Homogeneous Charge Compression Ignition (HCCI) allows for diesel-like operation wherein compression, not spark, combusts lean air/gasoline ...

No single type of air compressor or vacuum pump works best across the board. But wobblepiston pumps represent what is arguably the most versatile pressure and vacuum technology on the market today.

We love ourselves a good oddball engine, and tiny, scrappy Mazda certainly must be responsible for more such engine concept patents per market-capitalization dollar than any other. We just discovered ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...
