Abstract (en)
[origin: EP0658691A1] In an internal combustion engine having an exhaust-gas brake device (5,51) in exhaust-gas pipe (4) and an EGR device (7,8) which returns part of the exhaust-gas from the exhaust-gas pipe upstream from this exhaust-gas brake device to the air-intake manifold (2), a suitable exhaust-gas-brake force can be obtained by setting the opening pressure required to open the exhaust-gas valve (30) to a value which allows the production of a suitable exhaust-gas-braking force but lower than the opening pressure required to open the EGR control valve (8) of EGR device. As a result, when the exhaust-gas brake operates, the leakage of exhaust-gas into the air-intake manifold is eliminated, and the desired exhaust-gas-braking force is achieved. <IMAGE>
