Diesel injectors have gotten increasingly complex over the last twenty years of diesel development, but their basic design is fairly simple. Diesel fuel from the injection pump enters the mechanical ...

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 ...

Fuel injectors are the heart of a vehicle’s fuel system. Because they keep the fuel supply running smoothly, when an injector experiences a problem, the whole engine suffers the consequences. Because ...

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 ...

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 ...

Diesel engines use compression to ignite the fuel, which needs to have an even burn, and cetane boosters have an important ...

Diesel truck fans may have heard the legends surrounding the 12-valve Cummins. Found in trucks like Dodge Rams from 1989 to 1998, its fully mechanical fuel system and rugged injectors are celebrated ...

Fuel injectors can get gummed up with dirt and fuel residue over time. Photo credit: David Traver Adolphus / Autoguide.com. Over time and miles, your car might start to slow down. It might not ...

Diesel engines are notoriously robust, but if the fuel they run on gets contaminated, the engine can suddenly become much ...
