Engine controller

摘要

The present invention provides an engine controller (1) which controls an actuator for selectively executing spark-ignited combustion and compression-ignited combustion of an internal combustion engine (13) in accordance with an engine operational state. The controller (1) is comprised of a deterioration recognition section (2) for recognizing a deterioration state of the engine or the actuator during the spark-ignited combustion. The engine controller (1) 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 (13) or the actuator recognized by the deterioration recognition section (2).
