Operation of the Motronic System In this section, let's look at operating conditions to see how Motronic controls injection and ignition as well as idle speed bypass air for good engine management [11 Starting Start Control. fuel In most Motronics, start enrichment is provided by the port injectors rather than the separate start injector/thermo-time switch For start control, the important inputs are rpm and engine temperature. The control unit monitors cranking rpm and also the number of revolutions since the time cranking began [2. The injection pulses may be longer than normal But at low engine temperatures, the control unit may deliver instead several shorter injection pulses per revolution to improve starting. Remember, these are 10 millisecond pulses in a pulse period, or crankshaft revolution time of 200ms
