Abstract (en)
[origin: EP0736672A2] The IC engine has a braking control operated by a throttle valve in the exhaust duct. The exhaust valve (1) of each cylinder is partially opened during engine braking to increase the cylinder pressure during the compression stroke and thereby enhance the engine braking effect. A hydraulic servo system operates on the valve gear to open the valve. The hydraulic servo comprises a hydraulic cylinder incorporated into the rocker mechanism of the valve gear, or interposed between the valve and the cam drive. The system can be incorporated into existing engine designs.
