<P>PROBLEM TO BE SOLVED: To provide an exhaust gas inlet casing of a turbocharger capable of applying an exhaust gas bypass system without arranging any bypass pipe. <P>SOLUTION: In an exhaust gas inlet casing 10 of a turbocharger 1 which compresses combustion air of an internal combustion engine, and forcibly feeds the air of high density into a combustion chamber of the internal combustion engine, an inner casing 21 and an outer casing 22 separate from each other are integrally coupled with each other. A space formed between the casings 21, 22 forms an exhaust gas flow passage 26 to guide exhaust gas exhausted from an internal combustion engine to a turbine nozzle 5. Exhaust gas bypass flow passages 44, 32, 22b are provided, which guide the exhaust gas branched in the middle of the exhaust gas flow passage 26 to the downstream side in the exhaust gas flow of a gas guide cylinder 7 mounted on an end forming a gas outlet side of the turbine nozzle 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
