Q1: How to judge the quality of automotive spark plugs?
A: To distinguish the quality of spark plugs, there are several factors to consider:
1. Material: The material of the spark plug directly affects its durability and performance. Generally speaking, platinum spark plugs are more durable than copper spark plugs and can provide more stable performance.
Â
2. Heat range: The heat range of a spark plug refers to its heat conduction ability, or in other words, the temperature range in which it can effectively operate. A too low heat range may cause carbon deposits on the spark plug, while a too high heat range may result in ignition failure. Choosing the appropriate heat range depends on the specific requirements of the vehicle.
Â
3. Electrode shape: The electrode shape of the spark plug can influence the ignition effect and combustion efficiency. Typically, Iridium electrodes are better than copper electrodes and can provide higher ignition capability and better combustion efficiency.
