4.11.1 Description Jaguar XK II рестайлинг

When starting a cold engine, catalyst light-off times can be improved by generating high engine out energy. The energy is mainly dependent on exhaust temperature and mass flow rate. This is achieved by retarding the ignition timing and increasing engine idle speed as well as adjusting fuel injection and valve timing. Cold Start Monitoring ensures that the intended catalyst light-off times are being achieved. If the intended control is not achieved, then a DTC will be set and the MIL illuminated.
