Abstract

Intake system for a motor vehicle engine comprising an engine (1), an exhaust line (6) for the exhaust gases, a path (11) for the recirculation of the low-pressure exhaust gases, this recirculation being controlled by a recirculation valve (7; T), and a high-temperature first heat exchanger (4) on the intake path operating at a first temperature level (9) upstream of the engine intake (5), characterized in that the system comprises a low-temperature second heat exchanger (14) on the intake path (9) operating at a lower second temperature level.
