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

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Formula 1’s next-generation power units are not even on the grid yet and they are already reshaping the competitive landscape ...

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 ...

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 ...

Infiniti has revealed an engine concept this year, and it is of the variable compression kind. While not the first of its type as a concept, this motor might bring a new line of internal combustion ...

It seems like every major automaker these days is using tricks like variable-valve timing - often in conjunction with forced induction - to eke better efficiency out of their engines while still ...

The compression ratio clarification wasn’t the only one issued by the FIA. For some time now, F1 has used ultrasonic fuel ...

Heavy duty diesel engines are designed for long hours and extreme loads, but even the toughest systems fail without early ...
