Abstract
A control apparatus and method for an internal combustion engine are provided for ensuring a stable combustion state and improving the fuel efficiency when an air-fuel mixture is burnt with self ignition while auxiliarily using a spark ignition. The control apparatus for an internal combustion engine which is operated in a plurality of modes including a torch self ignition combustion mode comprises an ECU. In the torch self ignition combustion mode, the ECU controls an internal EGR amount, calculates an actual exhaust closing angle, calculates a target exhaust closing angle, calculates a closing angle deviation, calculates a fuel injection amount for forming a homogeneous air-fuel mixture, calculates a correction coefficient in accordance with the closing angle deviation, and corrects a basic value by the correction coefficient to calculate a fuel injection amount for forming a stratified air-fuel mixture.
