摘要： An cylinder valve controlling apparatus comprises a first rocker arm and a second rocker arm cooperating with a middle lift cam and a low lift cam, respectively, to active two cylinder valves arranged for each of the engine cylinders, respectively. The apparatus further comprises a free rocker arm cooperating with a high lift cam. During engine operation at low speeds, the first rocker arm activates one of the cylinder valves in accordance with the profile of the middle lift cam, while the second rocker arm activates the other cylinder valve in accordance with the profile of the low lift cam. During engine operation at middle speeds, a coupling including a first lever establish drive connection between the first and second rocker arms and thus the first and second rocker arms follow the profile of the middle cam. During engine operation at high speeds, with the first-mentioned coupling maintaining the drive connection, another coupling establishes drive connection between the free cam follower and the first rocker arm. Thus, the first and second rocker arms activate the corresponding cylinder valves in accordance with the profile of the high lift cam.

摘要： In a decompression braking apparatus which is applicable to a Diesel engine and is capable of switching an engine braking condition so as to achieve an appropriate braking force depending upon an engine revolution speed area when a decompression braking request is issued, an eccentric bushing member is pivotally interposed between an inner periphery of a rocker arm and an outer periphery of a rocker shaft fitted into the rocker arm so as to be enabled to displace a swing center of the rocker arm to a first position at which a degree of openings in a closure stroke of an exhaust valve whose valve stem is linked to the rocker arm is relatively small and to a second position at which the degree of openings in the closure stroke thereof is relatively large and an actuator having a plunger linked to the eccentric bushing member hydraulically actuates the eccentric bushing member to pivot so that the swing center of the rocker arm is displaced to either of the first or second position depending on an engine revolution speed when a decompression braking request is issued.
