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 ...

Higher octane fuel is necessary for engines that use higher compression. Low-octane fuels are less compressible and ignite ...

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 ...

We may receive a commission on purchases made from links. While browsing auto repair and maintenance tools at your local parts store, you've likely come across compression testers like the Orion Motor ...

Gasoline and diesel engines are very different. The former rely on spark ignition while the latter use compression ignition. Diesel engines typically run at much higher compression ratios than ...

Hydrogen offers a compelling pathway to decarbonise compression-ignition (CI) engines by leveraging its high energy density, wide flammability limits and rapid flame propagation. In conventional ...

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 ...
