ABSTRACT:
Apparatus and method for integrating mass air flow for a specified cylinder event in the intake tract of an internal combustion engine. The respective outputs of a mass air flow sensor and a directional air flow sensor are used to determine an accurate net integrated value of mass air flow. The magnitude of mass air flow is sampled and electronically integrated several times during each specified engine event in either a positive or negative sense (depending upon air flow direction) to obtain a net mass air flow value, which is then input to a A/D converter and then a microprocessor in an engine electronic control unit for use in engine management control.
