摘要： In a fuel injection type internal combustion engine including a cylinder body with a cylinder chamber, a cylinder head, a piston adapted to be reciprocated within the cylinder chamber, an injection nozzle having its central axis inclined with respect to the top of the piston and its injection port offset from the center of the cylinder chamber, and a combustion chamber cavity opened in the top of the piston, an auxiliary cavity defined by a notched wall having complicatedly cut surfaces is formed in the opening portion of the combustion chamber cavity. The notched wall is formed in a manner to follow the conical surface of a cone, in response to the piston travel, the cone having as its apex a point located upstream of the injection port, as its center the central axis of the injection nozzle, and as its apex angle the maximum spray diverging angle of the injection nozzle. With this structure, the collision of injected fuel against the combustion chamber cavity wall is prevented while minimizing the reduction in the compression ratio of the engine.
