摘要： There is provided an intake air amount control system for an internal combustion engine, which controls the amount of intake air by executing both cam phase control and valve lift control, and is capable of enhancing response and accuracy of the intake air amount control, while avoiding interaction between the cam phase control and the valve lift control. In the intake air amount control system 1, an ECU 2 controls the amount of intake air according to a target valve lift Liftin_cmd and a target cam phase Cain_cmd. The Liftin_cmd and Cain_cmd are respectively calculated as the sums of master values Liftin_cmd_ms and Cain_cmd_ms for causing an actual intake air amount Gcyl to converge to a target intake air amount Gcyl_cmd, and slave values Liftin_cmd_sl and Cain_cmd_sl set according to the master values Liftin_cmd_ms and Cain_cmd_ms (steps 56 and 64). In a lift master mode, Cain_cmd_ms is set such that Cain_cmd_ms=0 holds (step 63), and in a phase master mode, Liftin_cmd_ms is set such that Liftin_cmd_ms=0 holds (step 55).

摘要： In an engine electromagnetic valve operating device (20), an intake valve (17) is opened and closed by means of a first electromagnet (21), which is fixed to a cylinder head, and a second electromagnet (22), which is pivotably supported on the cylinder head by a fixed shaft (38) so as to be capable of swinging, attracting a first attraction face (23b) and a second attraction face (23c) respectively of an armature (23) having one end pivotably supported on the cylinder head by the fixed shaft (38) so that it can swing and having the other end abutting against a stem (18) of the intake valve (17). In this arrangement, by changing the angle between the first and second electromagnets (21, 22) by swinging the second electromagnet (22), the amount of lift of the intake valve (17) can be changed freely. Furthermore, since only at least one of the first and second electromagnets (21, 22) needs to be made to swing and, moreover, it is unnecessary to move the position of the armature (23), it is possible to form the electromagnetic valve operating device (20) compactly.

摘要： In a variable stroke engine comprising a plurality of links (60, 61) connecting a piston (11) with a crankshaft (30), a control member (65) disposed on an engine main body so as to be moveable in two directions over a prescribed range relative to the engine main body, a control link (63) connecting one of the plurality of links with the control member and an actuator (AC) for displacing the control member, the actuator comprises a ratchet mechanism that utilizes a force transmitted from the piston to the control member as an actuating force for the control member. By providing a spring member (73, SP, 121) that applies a biasing force to the control member, an appropriate actuating force can be applied to the control member in either direction.

摘要： A rocker arm (63) is provided with a valve connecting portion (63a) into which tappet screws (70) abutting against a pair of engine valves (19) are screwed so that their advance/retract positions can be adjusted, and the rocker arm (63) has a cam abutting portion (65) which abuts against a valve operating cam (69) and is interlocked and connected to the engine valves (19). The rocker arm (63) turnably connects to one end of a first link arm (61) turnably supported at a fixed position of an engine body and to one end of a second link arm turnably supported by a displaceable movable support shaft (68a). The rocker arm (63) is formed so that the valve connecting portion (63a) has a larger width in a direction along a rotating axis of the valve operating cam (69) than in the remaining part. This enables the lift amount of the engine valves to be continuously varied. It is also possible to reduce the size of the system, while ensuring follow-up ability of the opening/closing operations.
