More Information
Summary:The invention relates to a combustion chamber structure of an internal combustion engine, which stabilizes fuel injection, improves fuel economy and purifies exhaust gas. An attachment hole (12) having a central axis (Ci) inclined toward the lower side of the ignition electrode is formed in the cylinder head (4), and the portion of the tip of the injector (11) inserted into the attachment hole (12), said portion being in contact with the attachment hole (12) on the upper side of the attachment hole, is located at a position retracted in the direction of the central axis (Ci) from the open end of the attachment hole (12). In the inner surface of the upper side of the mounting hole (12), a portion extending from the tip of the injector (11) to the opening of the mounting hole (12) becomes a remaining inner peripheral wall surface (13). The angle of inclination ([theta] f) formed by the remaining inner peripheral wall surface (13) and the joining surface (F) is smaller than the angle of inclination ([theta] i) f
