Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why that is and what it means.

We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...

Compression in a diesel engine is essential for effective and efficient performance. And when compression is lacking, damage can result. That is why it’s imperative to know whether your engine’s ...

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 ...

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 ...

Formula 1 has not yet turned a wheel under its 2026 regulations, yet the first major political battle is already raging in ...

The automotive industry continues to be a hotbed of innovation, with activity driven by factors such as auto-ignition properties of the fuel, fuel concentration, and residual rate, and growing ...

Something I've been kicking around for a while, and wanted to get opinions on: Is there a reason we can't use variable intake valve timing to "optimize" engine operation for E85 operation, while still ...
