Braking system for a vehicle engine has a nominal performance in the braking mode which a specified amount of the nominal performance in the drive mode

摘要

Braking system has a nominal performance in the braking mode which is 1.6 times the nominal performance in the drive mode. The nominal throughput in the braking mode is at least 80% of the nominal throughput in the drive mode. The ratio of the turbine input pressure to the compressor output pressure in the nominal point of the engine braking performance is at least 2.
