ME-SFI part load/full load operation, function - GF07.61-P-3016V
ENGINE 273.961 in MODEL 216, 221 up to Model Year 8
Shown on engine 272
Part load operation: When the engine is at operating temperature optimal emission levels and good fuel consumption are assured in combination with the lambda control.
Full load operation: Maximum engine torque is produced at a pedal value of > 90 %. The injection time is extended accordingly for this purpose.
The particular quantity of fuel is metered to the engine in line with the performance map. The fuel quantity depends on:
- Coolant temperature
- Intake air temperature (only in warming-up phase)
- Engine speed
- Engine load
- Closed-loop mixture control
- Intake manifold length
- Tumble flap position
- Camshaft position
- Ignition angle.
