Although the spark plug of a car is a small part, it plays a very important role in the operation of the car. Once damaged, the common manifestations include unsmooth acceleration, abnormal ignition, difficulty in starting, and increased fuel consumption.
The signs that the car spark plugs need to be replaced are as follows:
1. The car is very unsmooth when accelerating. This is because the electrode gap of the spark plug becomes larger, so that it cannot provide continuous and stable energy well, so the car will not be smooth when accelerating, there will be Jitter occurs.
2. There is carbon deposits on the spark plugs. The carbon deposits are caused by the insufficient combustion of the oil, and the carbon deposits on the spark plugs cannot be ignited normally, so it is necessary to replace the new spark plugs at this time.
3. The car is extremely difficult to start, and sometimes it can't start at all. We need to check whether the spark plugs are in good condition. Every spark plug should be checked, not just one.
4. The fuel consumption of the car will increase, the ignition system of the vehicle is not in good working condition, and the mixed gas is not burnt sufficiently, thus causing the fuel consumption of the car to increase.
The replacement cycle of spark plugs is generally based on the driving of the vehicle.mileageWhen it reaches 20,000 to 30,000 kilometers, if some spark plugs are made of precious metals, the replacement cycle will be longer. Generally, the mileage of the vehicle reaches 60,000 to 100,000 kilometers before replacement. This replacement cycle is not fixed, it is just a rough reference, and the specifics still depend on the usage of the vehicle.
