Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the ...

At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...

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 ...

Additive manufacturing has enabled targeted thermal expansion to boost effective compression beyond the limit set for the 2026 season.

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 ...

Compression ignition basically is the term that is used for describing the manner in which diesel engines function. It happens when intake air—which often is combined with recirculating exhaust gas—is ...

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an engine's fuel efficiency?

What makes a diesel engine different to a regular gas engine, and is one better than the other?

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Want to know how healthy or unhealthy your engine really is? Get yourself a compression tester and find out. Despite how complex many modern vehicles are, you can do many common repair and maintenance ...
