Abstract
Systems and methods for determining the presence or absence of cylinder misfire of an internal combustion engine are presented. In one example, a threshold for establishing or denying the presence of cylinder misfire is determined via engine acceleration amounts of active and non-active cylinders. Engine acceleration values are then compared to the threshold to determine the presence or absence of cylinder misfire.
