Unlike standard automotive gasoline systems, the 4M51 utilizes heavy-duty spill valves or SCV modules to control high-pressure diesel injection timing and fuel volume.

The 4M51 engine utilizes an electronic control system to manage fuel injection timing, fuel quantity, and emissions. The ECU acts as the brain of this system, processing data from various sensors to actuate the fuel injection pump (often a Bosch VP44 or Zexel VRZ type radial plunger pump, depending on the specific model year and emission standards).
