Valve operating system in internal combustion engine
An actuator (51 1 ,51 2 ) is connected to one of components forming a power transmitting device capable of transmitting a power provided by a valve operating cam provided on a cam shaft (28), so that the actuator (51 1 ,51 2 ) can drive an engine valve (VI) in a lift amount which is obtained by addi...

| description | An actuator (51 1 ,51 2 ) is connected to one of components forming a power transmitting device capable of transmitting a power provided by a valve operating cam provided on a cam shaft (28), so that the actuator (51 1 ,51 2 ) can drive an engine valve (VI) in a lift amount which is obtained by addition of a lift amount of the engine valve (VI) based on a cam profile of the valve operating cam and a lift amount of the engine valve (VI) based on the operation of the actuator (51 1 ,51 2 ). Thus, a portion of the lift amount of the engine valve (VI) is borne by the valve operating cam, whereby a valve-opening power borne by the actuator (51 1 ,51 2 ) can be reduced, as compared with a system designed so that the engine valve (VI) is driven by only the actuator (51 1 ,51 2 ) only. The amount of electric power consumed by the actuator (51 1 ,51 2 ) can be smaller. |
