The precursor to the spark plug need to be replaced, why should the spark plug be replaced

The spark plug has a great influence on the engine performance, and it also determines the performance of the car. Someone asked why the spark plug should be replaced. The reason is very simple. The spark plug has a service life and will accumulate carbon after long-term use. If it is replaced irregularly, the engine will have trouble starting, insufficient power, increased fuel consumption, and excessive exhaust. If the spark plug is broken, the engine will not work normally, the car will naturally not be able to drive, and it needs to be replaced in time. When does the spark plug need to be replaced? What are the signs that spark plugs need to be replaced?

The replacement cycle of spark plugs is generally 20,000 to 100,000 kilometers. The replacement cycle of spark plugs of different materials is different. The ordinary nickel alloy spark plugs can be replaced once for 20,000 to 30,000 kilometers. The better iridium and platinum spark plugs can be used6 It will be replaced after 80,000 kilometers.

Precursor of spark plug replacement

1. Weak acceleration

whendiscoverWhen the car is accelerating, the engine jitters abnormally, 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 speed jitter

If the car engine is running at idling speed, there is a relatively large jitter, it 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. Difficulty in starting

If the car engine is difficult to start, it is a problem with the ignition system. It may be a problem with the spark plug. If there is an unexplained flameout, it is likely that more than two cylinders have stopped working.
