  • Ceramic precombustion chamber construction of internal combustion engine
    Patent number: 4809654
    Abstract: A ceramic precombustion chamber construction of an internal combustion engine includes at least one ceramic body having a circular cross-section, a metal ring in which the ceramic body is fixed by shrinkage fitting, and at least one key interposed between the ceramic body and the metal ring for preventing rotation therebetween. Contour lines of a key receiving notch formed in an inner circumference of the metal ring are positioned on inner sides of contour lines of a key receiving notch formed in an outer circumference of the ceramic body. With the arrangement, the ceramic body is prevented from loosening from the fitting with the metal ring due to heat and vibration in use and is prevented from being damaged resulting from cracks occurring in the ceramic body.
