Exhaust gas recirculation system

摘要

An EGR system comprising a take-out port of the exhaust gas located downstream of the catalytic converter and upstream of the muffler, and an EGR control valve provided at the confluent portion of the intake air and the recirculated exhaust gas. The EGR control valve controls the amount of the recirculated exhaust gas by means of a slide valve therein which varies the opening area according to the electric current from the engine electronic control unit.
