Let's discuss something that is well known by diesel mechanics and hard-core enthusiasts but may not be fully understood by new diesel owners or people who may have heard the term "compression ...

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 ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they can survive that punishment starts with how fiercely they squeeze the air ...

The automotive industry continues to be a hotbed of innovation, with activity driven by factors such as auto-ignition properties of the fuel, fuel concentration, and residual rate, and growing ...

We love ourselves a good oddball engine, and tiny, scrappy Mazda certainly must be responsible for more such engine concept patents per market-capitalization dollar than any other. We just discovered ...

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 ...

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

For hundreds of years of human history, the invention that has defined our ability to travel, explore, and expand our boundaries has been the combustion engine. This hallmark of mechanical development ...

In response to stricter global emissions standards, automakers are looking for new ways to wring every last bit of efficiency out of the internal-combustion engine. In this Engineering Explained video ...

Dim’s fascination with cars began when he was just six. Born into a family of car enthusiasts and racing drivers, he started learning basic mechanics and driving from an early age. While he loves ...

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 ...
