The spark plug is the heart of the engine. Although it is small, once it has a problem, it will cause the engine to produce misfire, insufficient combustion, and carbon deposits. Just like the human body is sick, the engine will show some signs before the spark plug has a problem. When the engine has these symptoms, we have to think that the spark plug has a problem.
What are the symptoms of spark plug aging
1. Decreased power and weak acceleration;
2. Idle speed jitter is more serious;
3. Difficulty in starting or sudden death.
The performance of spark plug replacement
Generally speaking, when you drive, ifFindWeak acceleration or the engine feels unusually jitter after stepping on the accelerator, which is probably caused by the decline in spark plug performance. When we stop and wait for the red light, we can pay attention to the working state of the engine. In the case of idling, the engine shakes obviously, or there may be a problem with the spark plug. If the engine is difficult to start, it is obviously an ignition problem. If you can rule out the general difficulty of ignition in winter or poor maintenance of the engine, then you can consider whether there is a problem with the spark plug.
How often does the spark plug change
Depending on the material, the material is different, the service life is not the same, and the replacement cycle is also different. Spark plugs are made of nickel alloy, iridium, platinum and iridium-platinum alloy.
①Ordinary nickel alloy spark plugs need to be replaced once for about 20,000 kilometers;
②Platinum spark plugs should be replaced at about 40,000 kilometers;
③Iridium spark plugs can be replaced after being used for about 60,000-80,000 kilometers;
④Cars that pursue more performance will use iridium platinum alloy spark plugs, which have better performance in all aspects. ReplacemileageIt can reach about 120,000 kilometers.
☑For how often to replace the spark plug, please refer to the recommended replacement cycle provided in the manufacturer's maintenance manual. Whether the spark plug is used for a long time, in addition to its own quality problem, is also affected by the overall performance of the engine, personal car habits and driving environment.
