西德鲍许公司最近设计了一种新型的宽热值范围的火花塞,以其四种热值代替了原标准型的九种,进一步适应了现代公路交通车辆载荷幅度变化很大的要求。在市内交通拥挤缓行至在高速公路上持续高速行驶的高功率发动机来说,一般的火花塞是很难适应的,经常出现敲缸、火花塞积碳及点不着火。 West Germany Baoxu company recently designed a new wide range of heating value of the spark plug, with its four kinds of calorific value instead of the original standard nine, to further adapt to the modern road traffic vehicles load range varies greatly. In the city traffic congestion to the sustained high-speed highway running on the high-power engine, the general spark plug is difficult to adapt, often knock knock, spark plug carbon and ignition.
