Abstract

PURPOSE: To improve combustion efficiency by producing a swirl in a mixture sucked into a combustion chamber.
CONSTITUTION: In an four cycle internal combustion engine having two intake valves 6a, 6b in an intake path 4 and an exhaust valve 7 in an exhaust path 5, the intake valve 6a has the diameter larger than that of the intake valve 6b to make an amount of mixture introduced from the intake valve 6a larger than that introduced from the intake valve 6b for producing an intake swirl in the mixture.
