Aren’t the Duramax (left) and 5.9L Cummins common-rail (right) injectors from Bosch similar looking?...The solenoids and upper bodies of the injectors are the same. The returns appear to be the same, ...

2003 - PACE Award Winner Siemens VDO Automotive What: Piezo Common Rail Diesel Direct Injection System Judge's Citation: With Siemens’ Piezo Common Rail Diesel Direct Injection System, the company ...

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 ...

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 ...

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 ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...
