The intricate dance of fuel and air in a diesel engine is a symphony meticulously orchestrated by the Engine Control Unit (ECU). In this comprehensive guide, we venture into the realm of older generation diesel engines, shedding light on how the ECU seamlessly manages fuel flow, air injection, and exhaust gas recirculation.
The Driver's Command: Initiating the Fuel Demand
It begins with a simple push on the accelerator pedal. This external fuel request is determined by two primary factors:
Correspondingly, the ECU processes this data, translating it into a direct request for a specific fuel quantity. This transformative procedure is facilitated through 'Driver Wish' maps. These maps ingeniously convert the accelerator pedal's potential meter signal into a quantifiable fuel amount set to be injected. Thus, the fuel request journey initiates from the driver's end, via the accelerator pedal.
Cruise Control: The Alternate ConductorAn intriguing deviation from the regular fuel request process is the role of cruise control. In its essence, setting the cruise control translates to a hands-free driving experience—no pedals involved. Instead, a specific speed is set. The engine control unit then takes charge, determining the exact amount of fuel needed to either attain or sustain that predetermined speed.
Here's a fun tidbit: the torque and power levels generated when using cruise control often result in a smoother, less aggressive driving experience compared to the more direct accelerator pedal inputs.
