Abstract
Four cycle internal combustion engine including an intake passage leading to an intake port formed in the cylinder head. The intake passage comprises a first passage section connected to the intake port with an inclination so that intake air-fuel mixture is introduced into the engine working chamber with a circumferential velocity component to produce a swirl in the working chamber. The intake passage further includes a second and third sections which together with the first section form a meandering substantially S-shaped passage to establish a stratified fuel distribution in the passage.
