Engine braking device for a turbocharged internal combustion engine

摘要

At least one bypass conduit (23), leading from the exhaust gas conduit (16,19), is provided upstream of the exhaust gas cutoff device (22). The bypass conduit issues in an area near to a turbine wheel (28). An air mass flowing through the bypass conduit flows through at least one nozzle opening in front of the turbine wheel into a flow channel (17) of the turbine (18). The nozzle openings are arranged at an angle differing from 90 degrees to an inflow surface of a turbine housing and are preferably arranged tangentially to the plane of the rear of the turbine wheel. The air mass flowing through the bypass conduit is fed via a nozzle opening at the free end of a dividing wall of a multi-flow turbine to a radial ring channel of the turbine.
