PURPOSE: To enhance the filling efficiency and prevent a drop in the effective compression ratio by furnishing the divergent passage leading to each cylinder in the supercharge system, with a check valve through which allows only air or mixture to pass in the direction to the cylinders.
CONSTITUTION: A suction passage 2 and a supercharge passage 3 are provided independently from the cylinder 1. The supercharge passage 3 is to supply the air, pressurized by a supercharger 11, compulsorily into the cylinder 1. Because the supercharge passage 1 is furnished with a check valve 19, supercharging will be finished automatically when the pressures in front and in rear of the check valve get balanced, and thus the phenomenon can be prevented that the mixture filling the cylinder 1 flows back to the supercharge passage 3. During partial loading, when no supercharging is made, the amount of mixture flowing back into the super-charge passage 3 can be minimized, so that drop in the effective compression ratio can be also prevented.
