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

摘要

The invention relates to a device for recirculating the exhaust gas from the engine (1) of an automobile, including a first exhaust-gas recirculation line (9), referred to as an EGR line, a first heat exchanger (10) provided on said EGR line (9) for cooling down the recirculated exhaust gases, and means (11) for treating the exhaust gases in order to limit the pH value of the condensates from said gases. The treatment means (11) are provided upstream from said first heat exchanger (10) along the path of the exhaust gases, and said heat exchanger (10) includes a heat-exchange bundle made of aluminum and/or an aluminum alloy.
