ABSTRACT:
A stratified internal combustion engine has a main combustion chamber for receiving a lean air-fuel mixture, a trap chamber for receiving a rich air-fuel mixture, a primary intake port for supplying the lean air-fuel mixture to the main combustion chamber, a secondary intake port for supplying the rich air-fuel mixture to the trap chamber and a partition between the primary and secondary intake ports. The primary and secondary intake ports merge at their upstream ends into a single general passage defined by an intake manifold. A single fuel injection nozzle is mounted on the intake manifold to inject fuel toward the upstream end of the partition so that the injected fuel is divided and distributed by the partition into the primary and secondary intake ports and thus into the main combustion chamber and the trap chamber, whereby a stratified combustion is achieved by a simplified engine construction.
