Control system for an engine

摘要

An engine control system for a direct injection-spark ignition type of engine determines a target load based on an engine speed and an accelerator pedal travel, determines target air-to-fuel ratio based on an amount of intake air and the target engine load, and determines an amount of fuel injection based on the target air-to-fuel ratio, so as thereby to control engine output torque balancing the target engine load even during a transitional operating state.
