摘要： The present invention is directed to an apparatus for operating at least one intake valve and at least one exhaust valve in an engine cylinder. The apparatus includes an exhaust valve operating assembly for operating the at least one exhaust valve of the engine cylinder, wherein the exhaust valve operating assembly is capable of producing an exhaust gas recirculation event. The apparatus also includes an intake valve operating assembly for operating the at least one intake valve of the engine cylinder. The apparatus further includes an exhaust modifying assembly for modifying the operation of the exhaust valve operating assembly during a predetermined engine operating condition and an intake modifying assembly for modifying the operation of the intake valve operating assembly during a predetermined engine operating condition.

摘要： An exhaust brake is incorporated with an internal combustion engine. The brake comprises an exhaust rocker arm actuated by an exhaust cam for operating an exhaust valve; a brake rocker arm actuated by a brake cam; a first contacting unit held by either one of the exhaust and brake rocker arms; a second contacting unit held by the other of the exhaust and brake rocker arms. The second contacting unit is contactable with the first contacting unit when an exhaust braking is needed. Only when the brake rocker arm is actuated by the brake cam upon need of the exhaust braking, there induces the contact between the second and first contacting units, which provides an integral action of the exhaust and brake rocker arms thereby to actuate the exhaust valve for establishing the exhaust braking.
