Mechanical injection systems rely entirely on engine driven components to meter, pressurize, and time fuel delivery. In these engines, a mechanical injection pump is driven by the engine's gear train ...

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 ...

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 ...

High-pressure common-rail injection technology has revolutionized the diesel industry. Over the last decade, it has allowed engine builders to run higher injection pressures (as much as 29,000 psi in ...

Wärtsilä has focused its technological developments in this realm on three main areas: Common-rail fuel injection for heavy-fuel engines; Humidification methods for reduction of NOx; and Dual-fuel ...
