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 ...

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 ...

High pressure common rail system can precisely control the injection time and injection pressure to improve the thermal efficiency of the engine. The injection characteristics of the system can affect ...

Bosch launched the first common rail system in 1997. The system is named after the shared high-pressure reservoir (common rail) that supplies all the cylinders with fuel. With conventional diesel ...

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 ...

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 ...

As part of an overall environmental strategy initiated 2 years ago to reduce its environmental "footprint" worldwide, Noble Corp., Houston, has targeted its diesel-powered drilling rigs for total ...
