Supercharged internal combustion engine i.e. supercharged diesel engine, has air recirculation pipeline hooked on suction pipeline, where recirculation pipeline has outlet which is emerged in channels of part of suction pipeline

摘要

The engine has a compressor placed on a path of a suction pipeline (1). A part of the suction pipeline is located in upstream of an inlet of the compressor, and is internally separated into two parallel channels (21, 22). An air recirculation pipeline (9) is hooked on the suction pipeline on both sides of the compressor. The recirculation pipeline has an outlet which is emerged in the channels (22) of the part of the suction pipeline.
