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 ...

The key ingredient to maximizing the peak performance of a diesel engine is increasing the amount of diesel being burned. On old mechanical-injection engines, the only way to do this was to modify the ...

Sandia National Laboratories researchers (left to right: Nathan Harry, Christopher Nilsen, Drummond Biles, and Charles Mueller) show off their prototype of ducted fuel injection module for diesel ...

High-pressure common rail fuel (HPCR) systems are standard on nearly every diesel engine today, from heavy equipment to over-the-road trucks, light-duty trucks, large generators and more. HPCR fuel ...

Diesel engines operate at higher compression ratios than gasoline engines, and fuel is injected under much higher pressure. An injection pump, usually driven by a belt or chain linked to the ...

To save time and money, you might want to learn how to clean fuel injectors without needing to rely on professionals. But do ...
