Abstract: A cylinder head cover, on which a breather chamber wall and control valve device are mounted is not enlarged while the capacity of a breather chamber is increased. For an internal combustion engine, control valve devices, which control the operation of a hydraulic valve stop mechanism that serves as a cylinder stop mechanism, and an outer chamber wall of a breather chamber wall that forms a breather chamber into which a blow-by gas flows, project in a predetermined direction and are mounted on the outer surface of a top wall of a cylinder head cover. When viewed in the predetermined direction, the outer chamber wall has an overlap section that overlaps with a part of the control valve device. Therefore, the overlap section is covered in the particular direction by the control valve device.

Abstract: A cooling control unit for a water-cooled multi-cylinder internal combustion engine having a cylinder deactivation mechanism for controlling the flow of coolant to prevent the internal combustion engine from being incompletely warmed up when the internal combustion engine returns to its operating condition with all of the cylinders being activated. A communicating passage communicates with a normally activated cylinder coolant jacket as a coolant passage formed for normally activated cylinders and a deactivation-programmed cylinder water jacket as a coolant passage formed for the deactivation-programmed cylinders to communicate with each other, and through which the coolant flows. A bypass passage diverges from the communicating passage and bypasses the deactivation-programmed cylinder coolant jacket. A diversion control valve is provided in a diversion section where the bypass passage diverges from the communication passage. A control member controls the diversion control valve in accordance with the operating state of the internal combustion engine.
