    摘要: A valve operating device (100) opens and closes a valve (2) of an internal combustion engine by driving a valve stem axially. A rocker cam (10) that rocks about a drive shaft (21) in synchronization with a rotation of the internal combustion engine includes a driving cam portion (11) and a lift restricting cam portion (12). A cam follower (41) lifts the valve by contacting the driving cam portion (11) slidingly so as to convert the rocking of the rocker cam (10) into an axial direction motion of the valve stem. A restricting member (42) formed integrally with the cam follower (41) in a rocker arm (40) prevents the cam follower (41) from separating from the driving cam portion (11) in cooperation with the lift restricting cam portion (12), and as a result, an irregular valve motion is prevented regardless of a rocking acceleration of the rocker cam (10).

    摘要: A variable compression ratio mechanism that changes the compression ratio according to the rotation angle of a control shaft, wherein a stopper is provided at the highest compression ratio side for regulating the rotation of the control shaft. Then, the output detected by a compression ratio sensor for detecting the rotation angle of the control shaft when the stopper is in an abutted state is read. An adjustment value is learned in order to revise the sensor output based on the detected output.

    摘要: A control system for an internal combustion engine having a variable valve operating mechanism capable of varying at least one of a valve lift and an operation angle of an engine valve continuously is provided. The control system comprises a detecting device that detects an operating condition of the variable valve operating mechanism and produces a signal representative thereof, and a controller that controls the operating condition of the variable valve operating mechanism in response to the signal from the detecting device. The controller is programmed to determine whether an operation responsiveness of the variable valve operating mechanism is lowered based on the signal from the detecting device and vary operational characteristics of the variable valve operating mechanism when the operation responsiveness of the variable valve operating mechanism is lowered. A control method is also provided.
