Internal combustion engine e.g. direct injection type oil engine, for motor vehicle, has injection device with aerodynamic conditioning units for causing ordered turbulent flow around determined injection axis in recirculated exhaust gases

摘要

The engine has an injection device (50) for injecting recirculated exhaust gases (G2) in an inlet pipe (22), where the device is arranged in interior and an outlet (40) of a recirculation pipe (36) in a manner that the device is traversed by the recirculated exhaust gases injected in the inlet pipe. The device has aerodynamic conditioning units (52) for causing ordered turbulent flow around a determined injection axis (X) in the recirculated exhaust gases. The device has a body (54) centrally determining a cylindrical shaft (56) for passing the recirculated exhaust gases.
