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 ...

The debate centres on the mandated reduction in compression ratio from 18:1 to 16:1 for the new power units, and ...

Even before the 2026 calendar year has begun, the first controversy under F1's new ruleset has already surfaced. It concerns the engine regulations, and more specifically the compression ratio of the ...

Answer:The compression ratio listed for any engine combo is always the static compression ratio, which is fixed via component selection and machining practice when the engine is built. As you've ...

Formula 1’s next great technical battleground may already be taking shape – and Audi is openly worried it could decide the ...

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 ...

You might already know that gasoline and diesel engines both operate using the same four-stroke cycle: intake, compression, power, and exhaust. However, a key difference between gas and diesel engines ...

For more than a century now, automotive engineers have struggled with an unavoidable balancing act when it comes to engine compression. Now, thanks to an innovation from Infiniti, they may get to ...
