Low pressure exhaust gas recirculation system

摘要: The engine (4), designed to recirculate a proportion of its exhaust gases, is fed with air through an inlet duct compressor (2) and has gases evacuated by turbine (5) pollution reducter (6) e.g. in the form catalytic converter, filter or NOx absorber. It gas recirculation pipe (9) valve (8), taken from branch after reducer, pressure difference between (10) outlet (11) ends controlled shutter situated downstream pipe's which can be incorporated silencer. recirculated are cooled coolint unit (3) located (2).
