An engine controller controls an actuator for selectively executing spark-ignited combustion and compression-ignited combustion of an internal combustion engine in accordance with an engine operational state. The controller is comprises of a deterioration recognition section for recognizing a deterioration state of the engine or the actuator during the spark-ignited combustion. The engine controller is configured to change at least one of a switching condition between the spark-ignited combustion and compression-ignited combustion and an operational condition for the compression-ignited combustion, during the spark-ignited combustion, in accordance with the deterioration state of the engine or the actuator recognized by the deterioration recognition section.
