具有80年代先进水平的新型氮化硅陶瓷电热塞于1991年初在河南省巩县通过省科委技术鉴定,并由巩县陶瓷厂投入批量生产。氮化硅材料具有耐高温、耐磨损、耐腐蚀等独特性能。电热塞采用这种材料,具有寿命长,起动快的特点,可解决柴油机冷起动比较困难的问题。传统的电热塞由于起动时间长(30～40s)、使用寿命短(300h)、点火次数少(300～500次)等缺陷而影响整机的可靠性。针对这一问题,国家将氮化硅电热塞的研制列为
With the advanced level of the 80’s silicon nitride ceramic glow plugs in early 1991 in Gong County, Henan Province, through the Provincial Science and Technology Commission identified by the Gongxian pottery factory into mass production. Silicon nitride materials with high temperature, wear resistance, corrosion resistance and other unique properties. Glow plugs use this material, with long life, fast start features that can solve the diesel engine cold start more difficult problems. Traditional glow plugs affect the reliability of the whole machine due to the short start-up time (30-40s), short service life (300h), and small number of ignitions (300-500). In response to this problem, the country will be developed silicon nitride glow plug as
