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.
| Rotational speed and load are the two most important input variables. |
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 sensoror 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.
