Summary:A homogeneous charge compression ignition engine for preventing knocking or misfires even if the air-fuel ratio deviates from a target value. The controller determines the possibility of misfires occurring due to changes in the air-fuel ratio based on a map showing the relationship of the air-fuel ratio and the timing at which the exhaust valve closes (EVC) when stable homogeneous charge compression ignition is enabled. When there is a possibility of misfires occurring, the controller retards the EVC. When there is a possibility of knocking occurring due to changes in the air-fuel ratio, the controller uses a map to advance the EVC.
