Abstract
When a homogeneous combustion is to be executed at a lean air-fuel ratio, a tumbling flow that whirls in the cylinder descending in the cylinder bore on the exhaust valve side and ascending in the cylinder bore on the intake valve side, is intensified by the fuel that is injected from the fuel injection valve toward the exhaust valve side in the cylinder bore in the last stage of the intake stroke.
