DEVICE FOR RECIRCULATING EXHAUST GAS FROM THE ENGINE OF AN AUTOMOBILE, AND USE OF SUCH A DEVICE

摘要

The invention concerns a device for recirculation of exhaust gases from an engine (1) of a motor vehicle, comprising a first exhaust gas recirculation line (9) called an EGR line, a first heat exchanger (10) provided on said EGR line (9) to ensure cooling of the recirculated exhaust gases, and treatment means (11) for the exhaust gases allowing limitation of the pH of the condensate arising from said gases. The treatment means (11) are provided upstream of the first exchanger (10) along the path of the exhaust gases, and the exchanger (10) comprises a heat exchanger bundle made of aluminum and/or aluminum alloy.
