DEVICE AND METHOD FOR RECIRCULATING EXHAUST GASES OF AN INTERNAL COMBUSTION ENGINE

摘要

The device has a recycling duct (13) whose one end is connected to an exhaust duct (5) of a heat engine (1), and another end is connected to an inlet duct (3) of the engine. A heat exchanger (16) is disposed on a section of the recycling duct for cooling recycled gas. The recycling duct has a bypass junction (17) at a downstream of the heat exchanger, where the bypass junction is connected to a bypass duct (19). The heat exchanger has inlet/outlet channels (21) for circulating a coolant between the exchanger and heat producing device. An independent claim is also included for a method for controlling exhaust gas of a heat engine.
