A running engine produces heat, which expands its metal body, thereby increasing its compression ratio. This is true for ...

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 ...

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

Car manufacturers are delving deep into their boxes of tricks to make internal combustion engines more efficient. Infiniti unveiled a variable compression ratio engine last year, and hybrid technology ...

Nissan engineers have reportedly been working on the engine concept for more than 20 years, and the company claims to have filed more than 300 patents protecting the design and associated technologies ...

With Infiniti having recently revolutionized internal combustion engines by the introduction of a variable compression ratio mill, we're here to take the time to zoom in on the tech introduced by the ...

Nissan’s variable-compression turbo (VC-Turbo) is a unique engine capable of variable compression adjustment. Unlike traditional engines, which have a fixed compression ratio, the VC-Turbo engine ...
