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 ...

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 ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Compression ignition basically is the term that is used for describing the manner in which diesel engines function. It happens when intake air—which often is combined with recirculating exhaust gas—is ...

Toyota makes some of the most durable trucks in the world—they’re so long-lasting, in fact, that they often go a full decade without major updates. That might change soon if an engine described in a ...

As Mazda and Infiniti have proved, there's a lot of innovation left in the internal-combustion engine. One of the more wild concepts we've seen is called Reactivity Controlled Compression Ignition ...

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 ...

Diesel engines and gasoline engines are so fundamentally different that it’s possible to do real damage simply by filling up your car with the wrong fuel. Converting a diesel engine to actually ...
