する内燃機関。 Two exhaust ports are formed in one cylinder, an exhaust valve is arranged in each of these exhaust ports, and these exhaust valves are configured to be opened and closed respectively by two cams formed on a camshaft, and further , in an internal combustion engine in which a manifold is connected to the two exhaust ports, the valve opening/closing time is changed by changing the relative positions of the two cams in the rotational direction of the camshaft to make the opening/closing times of the two exhaust valves different. In addition to providing a mechanism, the valve opening/closing time changing mechanism is controlled by a control device that inputs data indicating the operating state and outputs a position fluctuation signal when abnormal noise is generated in the exhaust pipe. internal combustion engine.
