SUPERCHARGING SYSTEM FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a supercharging system for an internal combustion engine enabling enhancement of responsiveness of a turbocharger.SOLUTION: A supercharging system S for an internal combustion engine includes: an air supply passage 2 for supplying air to the internal combustion engine; an exhaust passage 5 for exhaust gas 51 discharged from the internal combustion engine; a turbocharger 3 for including a compressor 3C in the air supply passage 2 and a turbine 3T in the exhaust passage 5, driving the turbine by using energy of the exhaust gas and compressing air to be supplied to the internal combustion engine by using the compressor coaxial with the turbine; an accumulator passage 44 branched from the air supply passage downstream of the compressor; a high-pressure container 4 that is connected to the accumulator passage and in which pressure is accumulated by inflow of compression air 24 compressed by the compressor; a high-pressure supply passage 42 for connecting the high-pressure container with the air supply passage; a high-pressure supply valve 43 arranged in the high-pressure supply passage; and a valve control section 8 configured to control a flow rate of the compression air 24 blown out from the high-pressure container to the air supply passage by controlling the high-pressure supply valve.SELECTED DRAWING: Figure 1
