Steuerungssystem zum Betreiben eines Dieselmotors mit Abgasrückführung

摘要

The system has an exhaust gas recirculation (EGR) loop (12) with an EGR valve (18) and an EGR valve (22) in a bypass (20) for controlling respective flow and temperature of a recirculated exhaust gas in an inlet of a diesel engine (10) of a motor vehicle. The loop is controlled by a control unit (32) according to a determined combustion noise level in the engine, where the level is determined by determination units.
