    • A method of controlling an internal combustion engine having at least one intake valve comprises the steps of (1) detecting a demand of the driver to the engine, (2) detecting operating parameters of the engine including engine rotational speed, and (3) setting the timing of closing the at least one intake valve to timing which makes output of the engine the maximum at the detected engine rotational speed, when it is detected that the driver demands that the maximum output of the engine should be obtained in at least a predetermined operating region of the engine. In another form of the invention, when the knocking of the engine is detected, the timing of closing the at least one intake valve is advanced or retarded by a predetermined amount from timing applied before occurrence of the knocking such that the engine has intake efficiency thereof lowered, at least in a predetermined operating region of the engine determined based on at least the detected demand of the driver to the engine and the detected engine rotational speed, and the advancing or retarding of the timing is continued even after the knocking of the engine ceases to occur.

    • A valve operating system for an internal combustion engine, including a cam having an arcuate base circle portion with the center thereof being aligned with the rotational axis of the cam and a raised portion projecting radially outwardly from the base circle portion, a cam-side piston operatively connected to the cam, a valve-side piston operatively connected to an engine valve, a hydraulic pressure chamber between the cam-side piston and the valve-side piston, an oil pressure supply source connected to the chamber through a check valve, a hydraulic pressure releasing valve connected to the chamber, and a solenoid valve or the like for controlling the operation of the releasing valve. This solenoid valve or the like is arranged to open the releasing valve to release the hydraulic pressure in the hydraulic pressure chamber in accordance with the operational position of the engine valve. This ensures complete seating of the engine valve and enables part of the working oil in the chamber to be periodically replaced to prevent excessive rise in oil temperature.
    • 一种用于内燃机的阀操作系统,包括具有弧形基圆部分的凸轮,其中心与凸轮的旋转轴线对准,并且从基圆部分径向向外突出的凸起部分,凸轮侧活塞 可操作地连接到凸轮,可操作地连接到发动机气门的阀侧活塞,在凸轮侧活塞和阀侧活塞之间的液压室,通过止回阀连接到室的油压供应源, 连接到室的液压释放阀,以及用于控制释放阀的操作的电磁阀等。 该电磁阀等被设置成打开释放阀,以根据发动机气门的操作位置释放液压室中的液压。 这确保了发动机气门的完全就座,并且能够定期更换腔室中的部分工作油,以防止油温过度上升。
