ABSTRACT:
A precombustion chamber construction of an internal combustion engine includes an upper ceramic body and a lower ceramic body abutting thereagainst to form a precombustion chamber communicating through an injection hole with a main combustion chamber. According to the invention at least a portion of abutting surfaces of the upper and lower ceramic bodies is inclined relative to a plane perpendicular to a longitudinal axis of the precombustion chamber, thereby preventing any relative rotative movement of the upper and lower ceramic bodies even if they are subjected to rotating forces caused by vibrations of the engine or explosion of fuel.
