Patent DE-4007287-A1 (DE)
Inventor: KUBIS HERIBERT DIPL ING
IPC: F01L13/06
Filed: 1990-03-08
Abstract: The invention relates to an engine brake for air compressing engines. To increase the braking power, the exhaust valve (1) is raised slightly even during the compression stroke, allowing additional braking work to be performed by the piston by virtue of the restricting effect of the exhaust valve. A hydraulic linkage (4) is inserted between the cam (2) and the exhaust valve (1) for the purpose of raising the exhaust valve. According to the invention, this linkage is activated in the braking mode by the closure, during the compression stroke, of a solenoid valve (12) connected in parallel with the linkage. The solenoid valve is controlled via sensors (20, 21) with the interposition of a control unit (19), the sensors interacting with the flywheel (23). By means of the closed position of the solenoid valve in braking mode, the exhaust valve can be raised by a second lobe of the cam in the compression stroke as well. By virtue of this measure, braking work is performed not only during the exhaust stroke but also during the compression stroke.
