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

Device for recirculating exhaust gas from the engine of an automobile, and use of such a device

A heat exchanger for the air supply circuit of a motor vehicle engine includes a heat exchange core and at least one header tank. The heat exchanger also includes an air flow rate control valve arranged in the header tank of the exchanger, and the control valve is a valve that includes a body with three openings and a moving rotary member inside the body so as to control the circulation of air through the heat exchange core and/or through a duct bypassing the heat exchange core according to a law defined as a function of the angular position of the rotary member in the body.
