としたことを特徴とする可変副室噴口燃焼室。 A sub-chamber type in which a sub-combustion chamber with a sub-chamber nozzle is located away from the cylinder centerline, and a protrusion is provided on the top surface of the piston to be inserted into the sub-chamber nozzle while the piston passes near the top dead center. In the combustion chamber of the engine, among the auxiliary chamber nozzle ridge lines at the cut plane of the auxiliary chamber nozzle taken by a plane including the auxiliary combustion chamber center line and the cylinder center line,
Let αL be the minimum angle between the ridgeline located on the cylinder centerline side and a plane perpendicular to the cylinder centerline, and the protrusion ridgeline at the cut plane of the protrusion by the plane including the auxiliary combustion chamber centerline and the cylinder centerline. If αR is the minimum angle between the ridgeline on the cylinder centerline side and a plane perpendicular to the cylinder centerline, then αL<αR
A variable pre-chamber nozzle combustion chamber characterized by:
