Abstract
PURPOSE: To actuate engine brake in an efficient and safe manner by opening an exhaust valve at a position near the top dead point of a piston at the end of compression stroke.
CONSTITUTION: A drive piston 11 and a drive piston follower 6 which produce pressure when they are driven by an exhaust-valve openig cam surface 7a of an exhaust cam 7 are provided at one end of a rocker arm 3 of an exhaust-valve opening and closing mechanism, while an actuator piston 4 which urges an exhaust valve 1 in its opening direction by said pressure produced by the drive piston 11 and drive piston follower 11 and a means for absorbing the reaction force of the actuator piston 4 are provided at the other end of the rocker arm 3. With such an arrangement, the exhaust valve 1 is opened at a position near the top dead point of a piston at the end of the compression stroke of the engine.
