Injection Control

OPERATION
Injection Control
The Digital Motor Electronic (DME) control unit calculates the correct injection time on the basis of the engine speed, air flow, throttle position, oxygen sensor voltage. engine temperature and intake air temperature. The mixture is varied by the opening time of the injector valves. The battery or system voltage is also taken into consideration in calculating the injection timing since the pull-up and drop-out times of the injector valves are extended as the voltage decreases.

Cylinder Individual Fuel Injection (CIFI)
Each injector valve is activated by its own output stage. Each cylinder can be programmed on an individual basis, i.e. duration and timing of injection.
