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
Ignition angle.

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.
