ABSTRACT:
A precombustion chamber construction for an internal combustion engine comprises a precombustion chamber constructed by a ceramic body having a glow-plug receiving aperture to be inserted in a precombustion chamber receiving cavity of a metal cylinder head. A metal sleeve may be fitted on the ceramic body. A seat is formed at an entrance of a glow-plug receiving aperture on an outer circumferential surface of the metal sleeve, thereby preventing any leakage of burnt gases to ensure the complete thermal insulating effect. The metal sleeve is not necessarily needed. In this case, the seat is formed at an entrance of the glow-plug receiving aperture on an outer circumferential surface of the ceramic body.
