Housing for use in compressor of turbocharger to recycle exhaust gases into combustion air stream, has nozzle arranged upstream to impeller inlet, where ratio of inlet inside diameter to nozzle inside diameter amounts to certain range

摘要

The housing (10) has a channel (12) provided for combustion air, which flows into a compressor impeller inlet (14). A nozzle (16) is provided for supplying recycled exhaust gas with pressure, which is lower than pressure of exhaust gas upstream to a turbine of a turbocharger. The nozzle is arranged upstream to the compressor impeller inlet. Ratio of inside diameter (20) of the compressor impeller inlet to inside diameter (22) of the nozzle is 0.625 - 1.4. The inside diameter of the impeller inlet amounts to 34 mm.
