Inside a diesel engine's cylinder, compressed air raises the temperature to ignite injected fuel, and the resulting force drives pistons to power the vehicle's main gears. Chief to this combustion ...

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 ...

A diesel engine is simultaneously incredibly simple and incredibly violent, using compression as a means of ignition. This is because of the properties of diesel fuel: Namely, diesel is less volatile ...

Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions ...

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 ...

While the purpose of a diesel engine is the same as a conventional one, to carry your car along the roads, there are several differences in how a diesel engine operates. From the fuel that it uses to ...

Diesel engines typically have beefier, more robust cooling components to keep the motor cool in varying conditions. Modern diesels operate at a higher compression ratio, which makes their combustion ...

The death knell has been ringing for diesel engines over the last decade, primarily because of their environmental impact. But some still swear by diesels for their abundant torque, efficiency, and ...
