An internal combustion engine 110 having a two stage turbocharger 900 and a charge cooling system 260 for the two stage turbocharger 900, the two stage turbocharger 900 comprising a high pressure compressor 240 and a low pressure compressor 540 for compressing intake air in a compressed air circuit 950, the charge cooling system 260 being equipped with an interstage cooler 267 fluidically connected to an outlet (544, Fig. 5) of the low pressure compressor 540 and to an inlet (242, Fig. 4) of the high pressure compressor 240, with a high pressure cooler 265 fluidically connected to an outlet (244, Fig. 4) of the high pressure compressor 240 and with a high pressure compressor bypass valve 600 being located downstream of the Interstage cooler 267 in a high pressure bypass duct 920 of the compressed air circuit 950 fluidically connecting an outlet (472) of the interstage cooler (267, Fig. 4), upstream of the high pressure compressor 240, with an inlet (474, Fig. 5) of the high pressure cooler 265, downstream of the high pressure compressor 240. The configuration exhibits an optimised layout allowing for easier routing and packaging of the connecting ducts. |
