How often do car spark plugs change?How to judge the spark plug should be replaced

Although the spark plug is small, it is powerful because it is the "fuse" of the engine.A clever woman can't cook without rice, without itFerrariIt can only accumulate dust. The performance of the spark plug affects the ignition effect and determines the power output of the engine. Therefore, timely inspection of spark plugs can ensure better performance of the engine. So how often do car spark plugs be replaced? How to judge that the spark plug should be replaced.

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.

1. Ordinary nickel alloy spark plugs need to be replaced once for about 20,000 kilometers;

2. The platinum spark plug should be replaced at about 40,000 kilometers;

3. Iridium spark plugs can be replaced after being used for about 60,000-80,000 kilometers;

4. Cars 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.

Please refer to the recommended replacement cycle provided in the manufacturer's maintenance manual for how often the spark plug should be replaced. 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. Therefore, learn to judge the signs of broken spark plugs in order to grasp the exact timing of replacement.

How to judge the spark plug should be replaced

The following conditions are for reference only, not necessarily spark plug problems. They can be caused by many reasons. Car owners should not replace spark plugs without authorization. It is recommended that they should be handed over to professionals in the repair shop in time for such situations.

1,Lack of motivation

whendiscoverThe engine jitters abnormally when the car is accelerating, which is probably caused by the deterioration of the spark plug performance. Decreased spark plug performance will cause the engine's ignition performance to plummet, and there will be a situation where acceleration is weak.

2, Idle jitter

If the car engine is running at idling speed and there is a relatively large jitter, there may also be a problem with the spark plug, and it should be checked or replaced in time. Of course, it may also be caused by the aging of the engine foot rubber or excessive carbon deposits in the intake duct in the cylinder. It is recommended to go to a professional repair shop for inspection.

3, Difficult to start

If the car engine is difficult to start, it is obviously a problem with the ignition system, which may be caused by a problem with the spark plug. If the engine stalls for no reason, it is likely that more than two cylinders have stopped working.

4, Fuel consumption increased

Abnormal ignition will cause insufficient combustion of the mixed gas and lower conversion efficiency. At the same time, more gas is required for combustion, which accelerates fuel consumption.

5, Exhaust pollution

Insufficient combustion gas can smell a strong smell, and even emit dense smoke at the outlet of the exhaust pipe. At this time, if there is a special measuring instrument, it will definitely detect that the harmful substances in the exhaust emissions exceed the standard.
