Electronic Engine Management

Function

The Motronic helps in keeping the expenditure of sensors low and considers influences of the fuel injection on the ignition and vice versa. It combines the control of the idle running, mixture formation and ignition in one device.

How it works

Under the concept of the engine management all control processes for the petrol engine are summarised. Ignition and/or mixture formation react, e.g., to the fine regulation of the idle running, to accelerator pedal changes and a knocking combustion.

Sensors

Inductive pickup at the flywheel and/or Hall-effect pulse generator at the camshaft, lambda sensor temperature (coolant), air mass flow sensor or pressure gauge in the inlet manifold with temperature (suction air), accelerator pedal or throttle switch.

Actuators

Injectors, stroke valve for fuel return, relay (fuel pump), idle running-filling regulator or throttle plate control motor, ignition coil.
