摘要： A method and a device for controlling the engine braking operation in internal combustion engines for motor vehicles, wherein the internal combustion engine is operated with direct injection of fuel and a controllable brake flap is provided in the exhaust gas system for retaining exhaust gases in the engine braking operation, and moreover has an exhaust gas recirculation device having an EGR valve that is arranged upstream of the brake flap and a recirculation line that connects the exhaust gas system to the intake system of the internal combustion engine and during the driving operation controls a defined quantity of recirculated exhaust gas with respect to the combustion air. To avoid critical excessive temperatures at the injection valves, in the engine braking operation (MB), the EGR valve (13) is more or less opened in dependence upon operating parameters (n, TE) of the internal combustion engine (1).
