Abstract
A cylinder injection type lean-burn internal combustion engine is capable of executing the purging of a vapor fuel without disturbing a state of an air-fuel mixture in a combustion chamber. The vapor fuel produced in a fuel tank is guided to a purge port provided at an intake passageway of the lean-burn internal combustion engine, and subsequently supplied along an intake air swirl flow into the combustion chamber. The vapor fuel is thereby partially concentrated in any one of a combustible air-fuel mixture layer and an air layer in the combustion chamber.
