摘要： In a compression ignition engine employing a variable valve actuation mechanism variably adjusting an intake valve characteristic including at least one of an intake valve lift and an intake valve closure timing, a control system operates to temporarily lower an effective compression ratio of the engine by controlling the intake valve characteristic during a cranking period of cold starting operation. At a point of time when a predetermined cranking speed threshold value has been reached owing to a cranking speed rise, the effective compression ratio is risen by controlling the intake valve characteristic. After combustion of the engine has been stabilized, the intake valve characteristic is brought closer to a desired value determined based on engine operating conditions by way of closed-loop control.

摘要： An internal combustion engine is provided with a valve lift varying mechanism for intake valves and a valve phase varying mechanism for exhaust valves. A controller performs a control operation in response to a request to pause at least one cylinder while the engine is in operation. The control operation includes: a first operation of setting an intake valve lift to a zero-lift setpoint by the valve lift varying mechanism; and a second operation of setting an exhaust valve phase by the valve phase varying mechanism so as to set an exhaust valve opening timing to a first timing setpoint on an advance side of bottom dead center and set an exhaust valve closing timing to a second timing setpoint on a retard side of bottom dead center. The first and second timing setpoints are closer to top dead center than to bottom dead center.

摘要： A valve operating mechanism of an internal combustion engine, comprises a drive cam rotatable with and eccentric to a drive shaft; a link arm having a circular opening in which the drive cam is rotatably received, so that rotation of drive cam about an axis of the drive shaft produces a swing movement of the link arm; a pair of swing cams swingably disposed on the drive shaft at both sides of the drive cam, the swing cams being connected through a movement transmission mechanism to the link arm to be swung when the link arm is subjected to the swing movement; a pair of swing arms respectively actuated by the swing cams for carrying out an open/close operation of a pair of engine valves; a pair of spring retainers respectively provided by the pair of engine valves; and a pair of valve springs respectively held by the spring retainers and biasing the engine valves in a close direction. A lubricating oil passage is formed in the drive cam. The oil passage has one end exposed to an oil feeding passage formed in the drive shaft and the other end exposed to a minute clearance defined between a cylindrical outer surface of the drive cam and a cylindrical inner surface of the circular opening of the link arm.
