    摘要: An intake valve control apparatus for an internal combustion engine includes a first variable valve operating mechanism (5) capable of varying an operation angle of an intake valve (3) continuously, a second variable valve operating mechanism (6) capable of varying a maximum lift phase of the intake valve (3) continuously, and a controller (10) that controls an intake air amount mainly by varying the operation angle and the maximum lift phase of the intake valve. The controller is configured to, when one of the first and second variable valve operating mechanisms (5, 6) is at a phase position different from a predetermined start stage phase position at engine start, correct a phase position of the other of the first and second variable valve operating mechanisms (5, 6) in accordance with a present phase position of the one of the first and second variable valve operating mechanisms (5, 6). An intake valve control method is also provided.

    摘要: A variable valve train device (110) is mounted on the engine head and is pivotable about the camshaft to alter the timing and lift of a intake valve. A command link (122) controls the rotational position of the apparatus with respect to the camshaft and is rotationally supported by a cylindrical shell bearing (126) mounted on the engine head coaxial with the camshaft. The shell bearing is supported by an hydraulic lash adjuster (128) or an adjustable ball joint to minimize mechanical lash in the device. The command link includes a ring gear (123) which meshes with a control shaft gear (28) for advancing or retarding the valve timing. The command link pivotably supports a rocker assembly (132) for following the rotary motion of the valve-opening and valve-closing cam lobes. The rocker assembly is linked to an output cam (140) disposed between the camshaft and a roller finger follower for actuating the valve.

    摘要: There is provided a valve timing control system for an internal combustion engine, which makes it possible to secure a right amount of combustion gases in a combustion chamber, irrespective of whether an EGR device is in operation or not, thereby obtaining a sufficient effect of reduced exhaust emissions by reduction of NOx. A crank angle position sensor and an intake pipe absolute pressure sensor detect operating conditions of the engine. An ECU determines whether the EGR device is in operation or not. A target cam phase is set in dependence on the detected operating conditions of the engine and a result of the determination as to whether the EGR device is in operation or not, and the cam phase is controlled to the target cam phase.

    摘要: In an internal combustion engine employing a variable lift and working angle control mechanism (1) and a variable phase control mechanism (21), a first sensor (14) is provided to detect an actual control state of the variable lift and working angle control mechanism every sampling time intervals. Also provided is a second sensor (16) that detects an actual control state of the variable phase control mechanism every sampling time intervals. At least one of the sampling time interval for the first sensor and the sampling time interval for the second sensor has a characteristic that the one sampling time interval varies relative to the engine speed. A rate of change in the sampling time interval for the first sensor with respect to the engine speed is different from a rate of change in the sampling time interval for the second sensor with respect to the engine speed.
