Abstract
An internal combustion engine in which component parts slide against each other during operation, the internal combustion engine including: a water supply device that supplies water to the sliding surfaces of the component parts; and a control device that controls an operation of the internal combustion engine. At least one of the sliding surfaces of the component parts is made of silicon-based ceramics. The control device controls the operation of the internal combustion engine such that a low load or a no-load operation in which an engine load is limited to a predetermined reference load or less is performed until a predetermined standby period elapses after the operation of the internal combustion engine is started, and controls the operation of the internal combustion engine such that a normal operation in which the engine load is not limited to the reference load or less is performed after the standby period elapses.
