With the Otto engine, the air-and-fuel system produces an air-fuel mixture which helps the engine to produce the required torque while also fulfilling additional requirements, e.g. as regards the exhaust system. The electronic control adjusts the optimal mixing ratio between air and fuel as well as the optimal time of injection.

The driver's requirement for more or less torque is a key input variable for controlling the air charge electronically. The accelerator-pedal module provides this information as a sensor signal.
