Valve drive for multi cylinder internal combustion engines, has each gas exchange valve actuator mounted in separate casing secured to common support frame

摘要

Each cylinder has a corresponding gas exchange valve actuator (46, 48, 52, 54, 56) mounted in its own separate casing (22) and these casings are mounted on a common support frame (20). Each cylinder has at least one gas exchange valve operated via a camshaft and actuators, which are both mounted on a support frame extending above the cylinder head (10).
