一、正确选用火花塞的型号。应根据不同的使用条件来选用不同热值的火花塞。发动机转速低,压缩比小,工作温度较低,应选用热型火花塞;反之应选用冷型火花塞。 二、安装火花塞时,应使用专用密封圈(锥座型除外)。安装前要在螺纹上涂一层高温润滑剂(不要流到火花塞电极上),以防损坏气缸盖螺纹或造成拆卸困难,并按规定扭矩扭紧。 三、定期调整电极间隙。使用中应定期拆下火花塞进行清洗,检查调整火花塞间隙。冬季应将火花塞电极间隙适当调小,夏季应将火花塞间隙调大。调整间隙时,只能变动旁电极,不能扳动中央电极,以防损坏绝缘体。
First, the correct choice of spark plug model. Should be based on different conditions of use to choose different calorific value spark plugs. Low engine speed, small compression ratio, low operating temperature, should be used hot spark plug; the other hand, should be used cold spark plug. Second, the installation of spark plugs, special seals should be used (except cone type). Before installation, apply a high-temperature lubricant on the threads (do not flow to the spark plug electrode) to prevent damage to the cylinder head threads or cause disassembly difficulties, and torque the required torque. Third, adjust the electrode gap regularly. Spark plugs should be regularly removed for cleaning, check and adjust the spark plug gap. Spark plug electrode gap should be properly adjusted in winter, the spark plug gap should be adjusted in summer. Adjust the gap, the only change the next electrode, can not pull the central electrode to prevent damage to the insulator.
