ME-SFI acceleration enrichment, function - GF07.61-P-3015V
ENGINE 273.961 in MODEL 216, 221 up to Model Year 8
Dynamic enrichment prevents jerking when accelerating.
If the throttle valve is opened quickly, a short-term mixed adaptation takes place. An additional quantity of fuel is added to the engine by the ME control unit in line with the performance map. The ignition angle is adjusted to "Early".
Fuel pressure fluctuations at the injection valves are prevented by the fuel distribution pipe by both the fuel pressure reservoir and the particular volume.
Acceleration enrichment is dependent on:
- Coolant temperature
- Load change rate (accelerator rate)
- Engine speed
- Engine load
- Intake manifold length and tumble flap position
- Camshaft position
- Correction programming with STAR DIAGNOSIS
