Abstract:
Various systems and methods are described for deactivation and reactivation of a cylinder bank in a V-engine. In one example, the cylinder bank is deactivated responsive to an indication of misfire based on crankshaft acceleration and exhaust air fuel ratio. The cylinder bank is reactivated sequentially based on exhaust catalyst temperature.
