御装置。In an internal combustion engine, the valve train is equipped with a hydraulically operated locking means for disabling predetermined intake and exhaust valves at a predetermined time, and the locking means is provided in a downstream oil passage on the discharge side of an oil pump that supplies hydraulic oil to the locking means. Selectively control the supply of hydraulic oil to -
A switching valve is provided, and an oil passage further downstream of the switching valve is divided into an intake valve oil passage leading to the intake valve locking means and an exhaust valve oil passage leading to the exhaust valve locking means. A delay valve having an orifice and a check valve is provided in each of the oil passage for the intake valve and the oil passage for the exhaust valve, and the delay valve for the intake valve oil passage and the delay valve for the exhaust valve oil passage are arranged in the direction of the check valve. are made different so that the delay directions are opposite to each other, thereby making it possible to cause a difference in the operational response of locking and unlocking the intake valve and locking and unlocking the exhaust valve. A control device for a valve train in an internal combustion engine that operates.
