摘要： In a variable valve actuation system of an internal combustion engine employing a variable valve actuator capable of variably adjusting at least intake valve closure timing depending on engine operating conditions, a processor of a control unit is programmed to phase-advance the intake valve closure timing to a predetermined timing value after a piston top dead center position and before a piston bottom dead center position on intake stroke during at least one of an engine starting period and an engine stopping period. The variable valve actuator includes a biasing device by which the intake valve closure timing is permanently biased toward the predetermined timing value.

摘要： In a control apparatus for controlling a variable valve actuation system employed in an internal combustion engine, engine/vehicle sensors are provided to detect at least a cylinder pressure in an engine cylinder for monitoring a change of state in combustion, arising from fluctuations in states/characteristics of air-fuel mixture such as a change in fuel property. Also provided is a control system that controls the variable valve actuation system responsively to a manipulated variable modified based on the cylinder pressure reflecting the change of state in combustion by a model of combustion.

摘要： On end of a reactor (L1) is connected to a positive electrode of a battery (B1) and the other end is connected to a power line via a transistor (Q1) and to the ground via a transistor (Q2). By PWM control of the transistors (Q1, Q2), an arbitrary increased voltage is obtained in the power line. It is possible to obtain an optimal inverter input voltage (power line voltage) according to the motor drive state, thereby increasing efficiency. Thus, it is possible to optimize the inverter input voltage according to the motor drive condition.

摘要： A rocker arm is swingably supported by a control shaft that has an eccentric control cam formed thereon. The rocker arm is swung by a torque of a crankshaft of the engine. Two swing cams are swingably supported by a drive shaft and actuate respective engine valves to make an open/close operation of the same by receiving the swinging movement from the rocker arm. The rocker arm comprises a cylindrical base portion through which the control shaft passes; a first projected end that is provided at a first radially outside part of the cylindrical base portion in the vicinity of one axial end of the cylindrical base portion, the first projected end receiving the torque from the crankshaft for carrying out the pivotal movement of the rocker arm; and two second projected ends that are spaced from each other and provided at a second radially outside part of the cylindrical base portion, the second projected ends actuating the two swing cams when the rocker arm is swung. The first and second radially outside parts are opposite with respect to an axis of the cylindrical base portion.
