Abstract: A method is provided for controlling an engine having an intake manifold and an outlet control device coupled to the manifold for controlling flow exiting the manifold and entering at least one cylinder of the engine. The engine further includes an inlet control device for controlling flow entering the manifold. The method includes providing an engine command; calculating a desired cylinder charge based on said command; and adjusting the outlet control device to provide said desired cylinder charge. The engine command may be, for example, a driver command, such as a driver torque command. Further, the outlet control device may be implement in with a variety of mechanisms. For example, in one embodiment the outlet control device is a valve of the engine having a variable lift. In one embodiment the outlet device is a valve having variable timing. Likewise, the inlet device may be adjusted in response to a variety of parameters.

Abstract: A method for controlling an engine having both an electronically controlled inlet device, such as an electronic throttle unite, and an electronically controlled outlet device, such as a variable cam timing system is disclosed. The method of the present invention achieves cylinder air charge control that is faster than possible by using an inlet device alone. In other words, the method of the present invention controls cylinder air charge faster than manifold dynamics by coordination of the inlet and outlet device. This improved control is used to improve various engine control functions.

Abstract: An internal combustion engine having electronic throttle control includes an air assisted injector system for directing a controlled amount of air directly to the combustion chamber without passing through the throttle body. A method of diagnosing faults in the air assisted injector system is disclosed. The method comprises the steps of measuring the airflow entering an intake of the electronic throttle of the engine at idle speed with the air assisted injector system operating at a first rate of airflow, turning the air assisted injector system off, measuring the airflow entering the intake of the electronic throttle of the engine at idle speed with the air assisted injector system off, and generating an error signal as a function of the two measured values.
