Exhaust gas recirculation for a supercharged internal combustion engine

摘要

The exhaust gas return system takes part of the exhaust gas from the two-stage turbocharged combustion engine (1). The exhaust gas flows along a bypass line (8) from between the high (3) and low (6) pressure turbines and is fed to the inlet of the low pressure turbocharger compressor (9). The bypass line is fitted with a control valve (10). Pref. an exhaust gas cooler (11) is also fitted in the bypass line.
