Abstract
An air supercharging device is provided for an internal combustion engine. The air supercharging device includes an air inlet, an electrical compressor, a heat exchanger and a cooling circuit. The cooling circuit includes an air intake conduit and an air recirculation conduit. The intake conduit extends between the outlet of the heat exchanger and the electrical compressor. The cooling circuit is configured to capture a fraction of the cooled compressed air. The air recirculation conduit extends between the electrical compressor and adjacent an inlet of the intake manifold.
Claims12
A supercharging device for supercharging an internal combustion engine, the supercharging device comprising:
- an air inlet,
- an electric compressor arranged to compress air coming from the air inlet;
- a heat exchanger arranged to cool compressed air coming from the compressor, the cooled compressed air flowing toward an intake manifold of the internal combustion engine;
- and
- a cooling circuit arranged to cool at least one of the electric compressor and a control device of the electric compressor, the cooling circuit comprising
- an air-conveying pipe arranged to convey air to at least one of the electric compressor and the control device, the air-conveying pipe extending between an outlet of the heat exchanger and at least one of the electric compressor and the control device, so as to be able to pick up cooled compressed air, and
- an air recirculation pipe extending between at least one of the electric compressor and the control device and adjacent an inlet of the intake manifold.
