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

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 ...

The compression ratio in Mercedes’ and Red Bull's 2026 engines has come under scrutiny in F1, but what’s really behind it?

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

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 ...

There’s still another couple of months before the 2026 crop of F1 cars takes to the track for the first preseason test. It’s a year of big change for the sport, which is adopting new power unit rules ...

The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

Ever since the first internal combustion engine hit top dead centre, engineers have been locked in an inexorable battle with compression ratios. Too low a compression ratio and the engine's efficiency ...
