It is well known that a high-pressure fuel injection is effective for the reduction in particulates and smoke emissions. Exhaust gas recirculation (EGR) is effective for the reduction in NOx emission.

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

Cold fusion, despite probably being impossible, is a good idea. Take a process known to create a meaningful amount of power and remove the harmful byproducts (like explosions), and you've got a winner ...

LIVERMORE, Calif. -- A "cool flame" may sound contradictory, but it's an important element of diesel combustion -- one that, once properly understood, could enable better engine designs with higher ...

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 ...

The diesel engine was one of the most ambitious engineering undertakings in history. It was so radical and high-minded that it still hasn’t been totally perfected—even after 150 years of development.

Despite sounding like a thoroughly entertaining evening out, it is actually a description for one of the most important processes in the majority of engines. Known as the four-cycle, it is the process ...

The California Air Resources Board has approved for 2027 what the Engine Manufacturers Association refers to as “sweeping new regulations affecting heavy-duty trucks sold in the state.” The regs ...

Diesel engines are the perfect recipients of mild engine modifications. They are considerably robust—generally much more so than gasoline engines. Without going into a diesel history lesson, this is ...
