Formula 1’s technical landscape is on the verge of a major flashpoint as manufacturers prepare for two high-stakes meetings with the FIA this week. The objective is to resolve a growing dispute over engine compression ratios,

As always, let’s take a look at the two main headlines from today, Sunday 1 February, in Formula 1. The FIA and engine manufacturers are set for a decisive week of talks, with two separate meetings lined up to address the long-running debate over the engine compression ratio.

Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel characteristics – diesel is less volatile than gasoline, heavier ...

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

Stock car racing engines are all about efficiency. That's because all the simple solutions for making power have either been maximized or eliminated by the rule book. You aren't allowed power adders like nitrous or a blower (lucky drag racers) and the easy ...

Nissan brought the first, and only, variable-compression engine to market. But its future doesn't look bright. Complexity in cars is a funny thing. It’s tempting to say that it’s all bad, that more is always less, but complexity has given us the ...

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 maintaining pure gasoline compatibility? NOTE: I don't ...

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 compressed (without the addition of heat) to point (b ...
