摘　　要：利用电加热产生高温的原理,通过对发动机缸内燃油加热点燃,从而提高柴油机在低温下的冷起动性能及降低蓝烟排放,快速发热金属电热塞的最快发热速度可达到850℃时间小于3s,普通金属电热塞发热速度可达到850℃时间小于7s。采用不同材料制作出不同性能特点的电热塞产品,同时不同性能特点的金属电热塞产品对于发动机的低温起动性能和减排效果有不同的影响。Using the principle of producing high-temperature through electric heating, the fuel oil is heated to certain temperature by glow plug in the diesel engine cylinder, so that the engine starting performance can be improved at low temperature, and blue smoke emission can be reduced too. The fastest speed of electric glow plug heating up to 850℃ may be less than 2s, and the heating rate to reach 850 ℃ of the general glow plug is about 7s. Using different materials can fabricate glow plugs possessing different performance and characteristics, and the glow plugs have different effects for engine cold starting performance and reducing emissions.
