摘要： A variable valve operating mechanism of a four-stroke internal combustion engine includes a slide pin energized by a pin spring in a direction while oil pressure acting on the slide pin in the opposite direction through oil pressure supply passages. The slide pin moves by controlling the oil pressure causing a stem contact surface and a stem through hole to selectively face a valve stem. The mechanism also includes an oil discharge passage including a discharge port which is opened to allow oil acting the slide pin to be discharged when the valve lifter is pressed by a valve operating cam to move for opening the valve. The mechanism is capable of quickly moving the slide pin upon the release of oil pressure when the valve comes into a quiescent state. Therefore, the response of transitioning the variable valve from an operating state to the quiescent state is improved.

摘要： A valve stopping mechanism wherein when hydraulic fluid pressure is low a cylinder operating state is set and a response of a switch from a cylinder stop state to the cylinder operating state is high. An intake valve and an exhaust valve, a first intake valve spring and a first exhaust valve spring are provided for energizing the valves in the direction of closing the valves, valve drive cams, valve stopping mechanisms, on the basis of a stop hydraulic fluid pressure and energization of plunger springs, for selectively generating valve operating and valve stop states. The valve stopping mechanism generates the operating state when the energizing force of the plunger spring is larger than the press force of the stop hydraulic fluid pressure and generates the stop state when the press force of the stop hydraulic fluid pressure is larger than the energizing force of the plunger spring.

摘要： 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.
