Our company mainly deals in oil trucks   Tanker   Refuelling vehicle    More than 100 varieties of oil tankers, warmly welcome customers to consult and purchase. Usually, the service life of spark plugs for oil tankers is 15,000 km, and the service life of long-acting spark plugs is 30000 km. The role of spark plugs in tank cars is to introduce high-voltage pulses generated by the ignition coils into the combustion chamber , using the electric spark generated by the electrodes to ignite the mixture , completing Burning .
The domestic spark plug model consists of three numbers or letters . The preceding number indicates the thread diameter , such as the number 1, indicates the thread diameter is 10mm, the middle letter indicates the length of the screw plug screwed into the cylinder part ; the last digit indicates the thermal type of the spark plug. :1-3 is hot type, 5 , 6 is medium type, and 7 or more is cold type . The " gap " of the spark plug is its main working technical index . The gap is too large , and the high voltage generated by the ignition coil and the distributor is difficult to skip . Causes the engine to start difficult ; if the gap is too small , it will lead to weak sparks , and prone to leakage .
There are two kinds of common faults in the spark plug of a tank truck : The spark plug is heavily ablated , the top of the spark plug is smashed, damaged, or the electrode melts, and the ablation shows that the spark plug has been destroyed and should be replaced . The spark plug has deposits , and the top of the spark plug insulator and the electrode Sometimes there are deposits that get stuck . In severe cases it can cause the engine not to work . For example, cleaning spark plugs can be remedied temporarily .
