PCT No. PCT/EP95/02972 Sec. 371 Date Aug. 2, 1996 Sec. 102(e) Date Aug. 2, 1996 PCT Filed Jul. 27, 1995 PCT Pub. No. WO96/05415 PCT Pub. Date Feb. 22, 1996An internal combustion engine includes an intake valve for controlling a cylinder intake port; an exhaust valve for controlling a cylinder exhaust port; first and second valve lifters coupled to the intake and exhaust valves, respectively, for cyclically opening and closing the intake and exhaust valves during normal engine operation; and an actuating device for contacting the exhaust valve and for operating the exhaust valve independently from the second valve lifter. The actuating device has a withdrawn position and a valve-contacting position. In the withdrawn position the actuating device is out of contact with the exhaust valve and in the valve-contacting position the actuating device is in contact with the exhaust valve. There is further provided an electromagnetically-operating setting device having an inoperative position assumed for a normal engine operation and an operative position assumed for an engine-braking operation. The actuating device is coupled to the electromagnetically-operating setting device such that in the inoperative position of the electromagnetically-operating setting device the actuating device is in the withdrawn position and in the operative position of the electromagnetically-operating setting device the actuating device is in the valve-contacting position. The electromagnetically-operating setting device further has a mechanism for operating the actuating device to open and close the exhaust valve when the actuating device is in the valve-contacting position.
