DEVELOPMENT OF CERAMIC PRE-COMBUSTION CHAMBER
A pre-combustion chamber (hot plug) made of silicon nitride ceramics has been developed. The hot plug is a component of the combustion chamber of swirl chamber diesel engines, and is subjected to the severest thermal load of all the diesel engine operating components. Unlike metal hot plugs, the ceramic hot plug requires a unique design approach to match the characteristics of ceramic materials. That is, a soft engine mounting is necessary to avoid the concentration of mechanical stress resulting from the high Young's Modulus of the ceramic and control of temperature distribution is also required to reduce thermal stress. Due to the heat insulating construction, the ceramic hot plug permits the combustion performance to be improved at low speed and load, resulting in improved noise and startability. Ceramic hot plugs are already being produced for diesel passenger cars.
