An engine cylinder deactivation mechanism

Abstract

The invention provides an engine cylinder deactivation mechanism. The mechanism comprises a cam shaft, a sleeve, a cam and thrust plates, wherein the sleeve sleeves the cam shaft, the inner wall of the sleeve is rotationally matched with the outer surface of the cam shaft, and the cam is fixedly arranged on the sleeve; the two thrust plates are oppositely arranged on the cam shaft and are in blocking connection with the two ends of the sleeve correspondingly; a locking hole is formed in the outer surface of the sleeve, the cam shaft is provided with a containing hole corresponding to the locking hole, a locking mechanism is arranged in the containing hole, and the locking mechanism is provided with a limiting piece which can extend into the locking hole; the limiting piece is provided witha locking position and an unlocking position, in the locking position, the limiting piece extends into the locking hole to realize the locking between the sleeve and the cam shaft; and in the unlocking position, the limiting piece retracts into the containing hole to release locking between the sleeve and the cam shaft. According to the engine cylinder deactivation mechanism, the oil consumptionof an engine can be effectively reduced, and oil saving of a whole automobile can be well achieved.
