ABSTRACT:
A system and method are disclosed for performing a plurality of diagnostic testing modes on an engine having a plurality of cylinders by controlling, independently, a mode of operation for each of the cylinders, each cylinder including intake and exhaust valves and a fuel injector for injecting fuel into a corresponding cylinder. A first method comprises the steps of cutting fuel to all but one cylinder, monitoring the output of the engine, repeating the fuel cutting and monitoring steps for the remaining cylinders, and calculating engine friction by averaging the power required to crank the engine by the cylinders during the monitoring steps. A second method for determining engine friction by averaging the power required by each cylinder to crank the engine, comprises the steps of placing a first cylinder in a load mode, cutting fuel to the remaining cylinders, monitoring an amount of power required to crank the engine and calculating engine friction using the monitored amount of power required to crank the engine.
