Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they can survive that punishment starts with how fiercely they squeeze the air ...

A newly published patent application details how to apply the efficiency tech to longitudinal engines.

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

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 ...

GM could make trucks sip fuel and make more power, but it's not going to be simple ...

Caterpillar (NYSE:CAT) and Phoenix Service Partners reported a breakthrough in ultra-low methane emissions for ...

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 ...

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 ...

We may receive a commission on purchases made from links. While browsing auto repair and maintenance tools at your local parts store, you've likely come across compression testers like the Orion Motor ...

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 ...

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 ...

Any certified gearhead knows that diesel engines do not use spark plugs. But why not? If power in an engine is created by combustion or explosion of flammable liquids, won't a spark plug in a diesel ...
