SUPERCHARGER PROVIDED ON TURBINE OUTLET WITH EJECTOR

摘要

PURPOSE:To use effectively energy of exhaust gas for an ejector to improve the efficiency of supercharger and increase the output of engine by providing the ejector jetting bypass gas on the outlet of turbine. CONSTITUTION:Bypass exhaust is jetted from a slit 8 provided right behind an impeller 1 in turbine casing 2 in the axial direction of turbine impeller 1 to accelerate and suck main flow gas from the impeller 1 with the effect of ejector. Thus, outlet static pressure of turbine impeller 1 is reduced to lower the pressure at turbine inlet 4 and engine exhaust outlet pressure and increase the output of engine. This means that nominal efficiency of supercharger is improved to increase the output of engine by using effectively the energy of exhaust gas for ejector to lower the turbine inlet pressure.
