Alternate left / right bank EGR loop operation to improve soil resistance during low mass flow engine operation

摘要

An installation for a vehicle, comprising: a diesel engine having an intake system and an exhaust system, a first EGR circuit connected between the intake system and the exhaust system having a first valve and a first radiator disposed therein, one between the intake system and the exhaust system connected second EGR cycle having a second valve and a second radiator disposed therein, and a control system that operates the first and second valves in a first condition in which both valves provide the engine EGR flows, and at least temporarily Raises currents in the first EGR circuit and lowers the flow in the second EGR cycle when the EGR flow is reduced to a condition in which deposition is enhanced in one of the radiator.
