Device for the thermal management of engine intake air

A device for thermal management of the intake air of an internal combustion engine equipped with a turbocharger, said device comprising:

• a first heat exchanger comprising an inlet and an outlet for heat-transporting fluid, placed in the air intake circuit between the compressor and the engine;
• a second heat exchanger placed on the main exhaust line of the engine, capturing the thermal energy from the exhaust gas and transferring said energy to a heat-transporting fluid circulating in the heating loop from an outlet and an inlet for heat-transporting fluid, the inlet for heat-transporting fluid of the first heat exchanger being connected to the outlet for heat-transporting fluid of the second heat exchanger, and the outlet for heat-transporting fluid of the first heat exchanger being connected directly or indirectly to the inlet for heat-transporting fluid of the second heat exchanger to form the heating loop;
• and
• a low-pressure exhaust gas recuperation system comprising a first take-off the exhaust gases placed on the main exhaust line downstream of the turbine, an outlet for the exhaust gases placed in the air intake circuit upstream of the compressor, and a control valve,
• the second heat exchanger is placed between the turbine and the first take-off for the exhaust gas recuperation system,
• wherein the main exhaust line further comprises a take-off branch for the exhaust gases between a second take-off for the exhaust gases placed on the main exhaust line upstream of the second heat exchanger, a take-off device able to manage the circulation of exhaust gases, and an outlet for exhaust gases.
