Abstract:
1. An internal combustion engine, comprising: a turbocharger that includes a turbine, and a compressor having an air inlet and a charge air outlet; an electronic actuator having an internal cavity; an intake manifold in fluid communication with the charge air outlet of the compressor through a cooled charge air passage; a bleed air passage fluidly connecting the cooled charge air passage at a bleed air point with the internal cavity of the electronic actuator, wherein a bleed air path is defined beginning at the bleed air point, passing through the bleed air passage, and passing through the internal cavity of the electronic actuator, further comprising an exhaust gas recirculation system disposed in fluid communication with an exhaust manifold and with the cooled charge air passage at a junction, wherein the junction is downstream of the bleed air point when the engine is in operation.
