Mechanism for variable valve lift and cylinder deactivation |
摘要 |
A valve lift mechanism for an internal combustion engine is disposed on the engine cylinder head. The valve lift mechanism has a rocker arm pivotally mounted on the stem of an engine intake valve that is slidably mounted in the cylinder head of the engine. The inlet valve is reciprocated by rocking motion of the rocker arm to control the opening and closing of an inlet passage in the cylinder to thereby control the incoming air/fuel mixture. A contact roller is mounted adjacent one end of the rocker arm on one side of the pivotal mount and a contact surface is formed along the rocker arm on the opposite side of the pivotal mount. A positioning mechanism including a roller is operable to selectively position a contact point between the roller and the contact surface to establish a rocking point for the rocker arm between a maximum lift position for the inlet valve and a minimum lift position of the inlet valve.
