The clearances inside diesel injection system parts are closer than those found in any other technology. The plungers and needle valves in injectors need to fit tightly to ensure precise metering and ...

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 ...

Iveco and Shell have collaborated in a test programme on diesel emissions, which has investigated the effect of diesel fuel properties, in conjunction with the effect of fuel injection timing, on 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 ...

Today’s diesel engines use high-pressure common-rail (HPCR) direct injection technology to provide greater efficiencies compared to conventional diesel engines. These engines operate under higher ...

UNSW researchers have prototyped and tested a retrofit system that converts diesel engines to run on 90% hydrogen, radically reducing both carbon dioxide and nitrous oxide emissions while boosting ...

Jasper Engines & Transmissions is remanufacturing the Bosch VP44 diesel injection pump. The pump was found on 1998-2002 Cummins B Series engines used in Dodge Ram pickups, Freightliner medium-duty ...

The carbureted car and truck era phased out by the early '90s. Carbs are still in use today on a few motorcycles, lawn mowers, and other power equipment, but electronic fuel injection (EFI) is ...
