Pressure charged engine exhaust braking system - increases power supplied to pressure charger to augment braking effect.

摘要

When braking the vehicle, the operating gas is compressed and at least partly extracted from the working chambers. To augment the braking effect, the degree of pressure charging is increased by supplying additional power to the pressure charger and thus raising its speed of rotation. In the case of an exhaust turbocharger, this can be done by reducing the cross-section of the turbine inlet by at least 50%. The flow of exhaust gas upstream of the turbine can also be throttled to increase exhaust gas backpressure.In the case of a mechanically driven charger, accumulated exhaust gas can be fed to the charge air delivered by it. ADVANTAGE - No need for exhaust gas cooling.
