Special car wrecker spark plug troubleshooting Tips
Spark plugs with good performance can improve the power performance of wrecker vehicles. In the maintenance of automobiles, more attention should be paid to the condition of spark plugs. Under normal circumstances, the service life of spark plugs is 15,000 kilometers, and the service life of long-acting spark plugs does not exceed 30,000 kilometers. However, the spark plugs of many wreckers often have problems like this, failing to reach their normal service life.
Spark plug ablating wrecker When the owner of the spark plug found that the top of the scar or damage, the electrode appears to melt, ablation phenomenon, all indicate that the spark plug has been destroyed, this time should replace the spark plug. During the replacement process, the owner can check the spark plug ablation conditions and changes in color. This phenomenon shows that
Burn room temperature is too high. This may be caused by too much carbon deposit in the combustion chamber, resulting in too small a valve clearance, further causing overheating of the exhaust valve or poor operation of the cooling device. When the wrecker spark plug is not tightened according to the specified torque, the electrode will be melted and the insulator will appear white. There is a deposit on the spark plug. There are sometimes deposits on the top of the spark plug insulator and between the electrodes. Owners should not underestimate this deposit. In severe cases, this condition may cause the engine not to work properly.
