GF07.61-P-3016CY ME-SFI Part Load/full Load Operation, Function
- up to model year 08


Partial load operation:
When the engine is at operating temperature, optimal exhaust emission values and low-cost fuel consumption are assured with the lambda control.

Full load operation
The maximum engine torque is supplied when the throttle valve is fully open. The injection time is extended accordingly for this purpose.

The relevant quantity of fuel is metered to the engine in line with the map. About a 10 to 90% slewing range on the accelerator pedal sensor (B37) is defined as partial load and more than about a 90% slewing range as full load.

The metered fuel quantity depends on:
^ Air mass
^ Intake manifold air pressure
^ Coolant temperature
^ Intake air temperature (only in warming-up phase)
^ Engine speed
^ Engine load
^ Lambda control
^ Engaged intake pipe length
^ Tumble flap positions
^ Camshaft positions
^ Ignition angle
