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 ...

The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the 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 ...

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 ...

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 ...

Each time I get behind the wheel of a Mazda equipped with the 2.2 SkyActiv-D, I don’t think to myself, “Oh no, another diesel-fueled disappointment.” Not only does Mazda know how to squeeze sufficient ...

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 ...

It's as crazy as it sounds. Rolls Royce developed a diesel rotary engine for military applications. Because diesel engines require high compression ratios for compression ignition to occur, they used ...
