Abstract
An air intake heater system for a combustion engine, comprising; a turbocharger, a high pressure EGR conduit, a low pressure EGR conduit, and an air intake conduit, where the system comprises a heat exchanger arranged upstream of the turbocharger, where the heat exchanger comprises a first flow channel connecting an air inlet to an inlet of the turbocharger and a second flow channel, where the second flow channel is part of the high pressure EGR conduit. The advantage of the invention is that intake air and low pressure EGR gas can be heated by the high pressure EGR gas, and that high pressure EGR gas can be cooled by intake air.
