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 ...

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 ...

Most people know that internal combustion engines require a fuel source to run. For many passenger cars and trucks, that fuel source is gasoline. However, many commercial vehicles, boats, farming ...

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 ...
