The fuel injection pump is the heart of the diesel engine. Precisely delivered fuel maintains a rhythm or timing that keeps the engine running smooth. Simultaneously, the pump also controls the amount ...

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 ...

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 ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Researchers have developed a promising yet surprisingly simple modification to diesel engines that could hold the key to reducing the complexity, maintenance, and size and weight of emission ...

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 ...

If you’re in fleet management or the construction industry, you undoubtedly have machines that run on diesel fuel. In addition to large trucks, more than 75% of all heavy construction equipment uses ...

Automotive engineers are very good at incremental improvements to existing technologies, and that skill will be much tested in meeting increasingly stiff fuel-economy rules between now and 2025. For ...

Lots of new car engines these days are built with both port and direct fuel injection. On the surface, that might not make much sense. Why would a carmaker use two different types of injection methods ...

How the 5.9L Cummins turbo diesel revolutionized pickup trucks in 1989, delivering 400 lb-ft of torque when Ford and GM ...
