Fuel injection system with common actuation device and engine using same

摘要

The present invention relates to engines having common rail fuel injection systems. In traditional common rail fuel injection systems, each fuel injector utilized by the fuel system includes its own solenoid. These individual solenoids must cooperate to ensure that the proper amount of fuel is being injected from each injector at the proper time. It is believed in the art that a reduction in the number of moving or electrical components in the fuel injection system can improve robustness of the system. Therefore, the fuel injection system of the present invention includes fuel injectors that are controlled in operation by a common electronic actuator that is positioned remote from the fuel injectors.
