PURPOSE:To prevent atmosphere pollution and pollution of related machinery by introducing a portion of intake air in an air intake pipe into an internal space of an internal-combustion engine and supplying mixed air of the intake air and blowby gas to an exhaust system and by performing mixing process of exhaust gas. CONSTITUTION:Exhaust gas exhausted from a combustion chamber 11 of a cylinder 5 is fed from an exhaust valve 13 to a turbo charger 16 through an exhaust pipe 15 to turn a turbine 21 and discharged from an exhaust pipe 18. A compressor 22 is driven by rotation of the turbine 21 to pressurize intake air from an air cleaner 17 previously and fed to the combustion chamber 11 from an air intake pipe 14 through an air intake valve 12. In this case, a portion of the intake air from the compressor 22 is fed to a crank room 8 through a branch pipe 31 and mixed with blowby gas leaked from the combustion chamber 11. And the mixed gas is discharged to the exhaust pipe 18 through a breezer pipe 35 to burn blowby gas by exhaust gas. |
