Abstract
A stratified-combustion internal combustion engine according to the present invention comprises at least two intake ports situated on one side of a combustion chamber, guide passages connected individually to the intake ports, a fuel injector disposed in one of the guide passages. Each guide passage has a straight region extending over a predetermined length from its corresponding intake port. Thus, an air-fuel mixture and air, guided by the respective straight regions of the guide passages to be supplied through their corresponding intake ports to the combustion chamber, flow along the axial direction of a cylinder bore, thereby forming barrel swirl flow separated in layers from each other.
