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

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 ...

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

"Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...

Opinions are divided about interpretations of compression ratio limits for engines in 2026. Controversies in the new season ...

There’s a new gas engine in town. Most recent vehicle powertrain news relates to electric drive designs. However, gasoline and diesel internal combustion engines still run the vast majority of ...

While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...

To meet stricter global emissions standards, carmakers are trying to squeeze every last bit of efficiency out of internal-combustion engines. That has led Infiniti to turn to a technology engineers ...

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 ...

The 2026 F1 season hasn't started yet, but there's already a major controversy brewing surrounding engines in cars being ...

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