PURPOSE:To always obtain an optimum accelerating performance, by providing main and auxiliary superchargers in parallel with each other and by controlling a control means for controlling the supply amount of accumulated air fed to an engine from a pressure accumulating tank connected to the auxiliary supercharger, in accordance with factors which is determined in accordance with the accelerating condition of the engine. CONSTITUTION:An auxiliary supercharger 3 such as a turbocharger or the like is connected in parallel with a main supercharger 2 such as a turbocharger or the like which is disposed in an intake-air pipe connected to an internal combustion engine. In the pipe line connecting between the auxiliary supercharger 3 and the intake-air pipe, there are disposed a pressure accumulating tank 4 and a control means 5 for controlling the supply amount of accumulated air to a desired value. Further, there is provided an accelerating factor detecting means 6 for detecting a factor in accordance with the accelerating condition of the internal combustion engine 1, such as the opening degree of a throttle valve or the like. Thus, the control means 5 is controlled by a control signal generating means 7 so that the accumulated air having an amount in accordance with the accelerating factor detected by the above-mentioned detecting means 6 is fed into the auxiliary supercharger 3 from the accumulating tank 4. |
