DIESEL COMBUSTION PERFORMANCE UNDER HEAT INSULATED CONDITION WITH CERAMICS

Studies have been underway to develop heat-insulated engines which use ceramic properties for low-heat conductivity and high-temperature strength. Most of the studies use ceramics only for heat insulation around the combustion chamber, which results in poor combustion characteristics. Therefore, in order to fully exploit ceramic characteristics, the study attempted to reduce fuel consumption through optimization of air density distribution in the combustion chamber, utilizing high-temperature ceramic walls. Further, exhaust smoke reduction was achieved by promoting both the mixing of diffuse combustion flame and air and also the oxidizing of soot. These are brought about by intensifying the in-cylinder air flow in a high-temperature ambient atmosphere.
