How often should the spark plugs be changed?

Check whether the spark plug needs to be replaced and removed to see if the color of the burning, the gap between the electrodes, the gap between the porcelain and the metal shell, etc.

In general, resistive spark plugs have a life of 20,000 km, Bojin spark plugs have a life of 40,000 km, and iridium spark plugs have a life of 6 to 80,000 km. Therefore, the original spark plugs of low-end cars are generally resistance spark plugs, while most of the original spark plugs of luxury cars and mid-to-high-end models are iridium spark plugs.

In addition, if the owner finds that it is difficult to start the car in a cool state, there is obvious frustration when driving, idle shake, or the engine acceleration performance is reduced, the spark plug should be checked in time. Because once the vehicle has the above performance, it may be caused by the aging of the spark plug.

Extended information: When the car travels to a certain number of kilometers, the spark plug will produce carbon deposition and electrode gap increase, carbon deposition will increase engine fuel consumption, and the spark plug gap will increase the starting difficulty. Therefore, frequent inspection and maintenance of spark plugs can prolong the life of the engine.

Maintenance begins with regular cleaning of the air filter to prevent dust from entering and burning with the mixture, which will prevent corrosion of the spark plug. Secondly, the owner can also remove the spark plug by himself to clean up the dirt and carbon deposits on the ignition head.

In particular, when disassembling and assembling the spark plug, it is necessary to pay attention not to let dust enter the cylinder when the spark plug is in and out, and the surrounding area should be cleaned in advance when disassembling the spark plug. If there is organic oil in the cylinder, the piston ring or other parts should also be replaced in time to avoid the short circuit of the electrode caused by carbon accumulation in the spark plug. In addition, fuel oil is also closely related to the life of the spark plug, so the owner must pay attention when refueling, and should not be greedy for cheap addition of quality problematic oil.

General normal maintenance recommended replacement kilometers in 40,000 to 60,000 kilometers. In addition, there are two situations that need to be replaced: first, the engine light is lit and accompanied by shaking during normal driving, and the fault code is read to show that there is a fire, and it is necessary to check whether the ignition coil and spark plug need to be replaced.

2. Remove the spark plug to check whether the ignition head is seriously ablated, and if it is serious, it needs to be replaced.

Replace it when driving 40000 60000 km under normal maintenance conditions, but it will vary due to different brands and engines, and it is recommended to follow the instruction manual. 1. The platinum spark plug is replaced at about 40,000 kilometers; When the performance is degraded, it is manifested as cathodic ablation, resulting in the change of ignition gap and the decrease of stability, so it is recommended to replace it regularly;

2. Ordinary nickel alloy spark plugs need to be replaced once for about 20,000 kilometers;It is recommended not to exceed 40,000 km, otherwise the ignition efficiency will decrease, resulting in a decrease in engine power;

3. Iridium spark plugs can be used for about 6-80,000 kilometers and then replaced, and when the performance declines, it is usually manifested as the aging of the ceramic insulation part, and the cylinder pressure decreases due to air leakage.

In addition to regular replacement of spark plugs, we should pay attention to maintenance, regularly clean carbon deposits to avoid excessive carbon deposits resulting in leakage and even no flashover, do not use sandpaper, metal sheets, etc. to clean the spark plug with a brush, and use a brush to clean the spark plug with the appearance of the ceramic body to prevent the appearance of the spark plug from wearing, and use the correct method to clean the spark plug.

Due to the different materials of spark plugs, the types of spark plugs can be divided into: ordinary copper core, yttrium gold, platinum, iridium, platinum-iridium alloy spark plugs, etc., the service life of these types of spark plugs is different, and the corresponding replacement mileage is also different, so it is necessary to distinguish clearly when choosing.

Generally speaking, under normal use, the service life of ordinary spark plugs is 30,000 kilometers, and the service life of spark plugs is 6 to 90,000 kilometers. Do not extend it so that it needs to be replaced at the right time.

If you find that the fuel consumption of the vehicle increases, you can consider whether to replace the spark plug, and the general repair shop will recommend replacing it after 20,000 or 30,000 kilometers, because although the spark plug is not completely damaged, the efficiency has decreased. In fact, this is determined by the quality of the spark plug, the ordinary spark plug can be changed once every 3-40,000 kilometers, and the platinum and iridium can be changed once for 680,000 kilometers. Generally in the tens of yuan to a hundred yuan.

Then find a reliable repair shop for installation, the installation process is very short, you can generally check it yourself, which can not only save money but also avoid the black heart repair shop to reuse the half-used spark plugs removed from other people's cars.

Replace <> 40,000 to 60,000 km under normal maintenance conditions.

Platinum spark plugs are replaced at about 40,000 km;When performance is degraded.

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

Iridium spark plugs can be used for about 6-80,000 kilometers before proceeding.

Hello, how often does the spark plug need to be replaced, first of all, it needs to be checked when the vehicle travels to 30,000 kilometers, and it needs to be replaced when the vehicle travels 40,000 kilometers, and the iridium spark plug can be doubled,

The replacement cycle of different types of spark plugs is not the same, the replacement cycle of ordinary electronic spark plugs is 20,000 kilometers, the replacement cycle of platinum spark plugs is 3-40,000 kilometers, and the iridium spark plugs can be replaced about 60,000 kilometers.

Hello, ordinary nickel alloy spark plugs need to be replaced once for about 20,000 kilometers; It is recommended not to exceed 40,000 km, otherwise the ignition efficiency will decrease, resulting in a decrease in engine power;

The spark plug is generally changed once every 60,000 kilometers, and when you go to maintain the car, the master will generally check it, look at your mileage, and the master will remind you to replace the spark plug.

Nickel alloy spark plugs are replaced about 20,000 kilometers; 2. Platinum spark plugs are replaced about 40,000 kilometers; 3. Iridium spark plugs are replaced about 60,000 to 80,000 kilometers.

Platinum spark plugs are changed once every 40,000 kilometers, and ordinary nickel alloys are changed once every 20,000 kilometers.

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

Platinum spark plugs are replaced at about 40,000 km;

Iridium spark plugs can be used for about 6-80,000 kilometers before being replaced.

Ordinary general spark plugs are required to be replaced for 40,000 kilometers according to the regulations, but there is generally no problem with a longer one, and it is recommended to replace it in time, and it is best to have a backup. FYI.

For the resistive spark plug used in conventional passenger cars, the electrode material is mainly copper-nickel alloy, the use consumption is relatively fast, the life is slightly lower, and the replacement frequency is higher, generally 20,000 kilometers can be replaced, and the maintenance manual of most models recommends 15,000 kilometers to be replaced, and the upper limit of use is 30,000 kilometers.

How often should the car spark plug be changed The service life of the car spark plug is different according to the material of the spark plug, and it is also different, and it cannot be unified.

How often the original spark plug is replaced is mainly determined by the material of the original spark plug.

If the original spark plug uses a resistive spark plug, the replacement cycle is to change it once every 20,000 kilometers.

If the original spark plug uses a platinum spark plug, the replacement cycle is 40,000 kilometers to replace it.

If the original spark plug uses an iridium spark plug, the replacement interval is 60,000 to 80,000 kilometers.

The replacement cycle of the spark plug will also be affected by the model and manufacturer, because the maintenance cycle specified by different manufacturers and different models will be different, so the specific replacement cycle of the original spark plug should be carried out according to the manufacturer's standard.

According to different equipment, spark plugs can be divided into many types, and the usage and life are also different. If the spark plug is not replaced for a long time, the car will shake, unable to speed up, or unable to catch fire, so the spark plug should be replaced in time. Spark plugs are used in cars and motorcycles.

At present, the spark plugs on the market are divided into resistance spark plugs, Bojin spark plugs and iridium spark plugs. Typically, the life of a resistive spark plug is 20,000 km; The life of the Bojin spark plug is 40,000 km; Iridium spark plugs have a service life of 6 to 80,000 km. These data can only be regarded as estimates, because the engine working conditions are different, the driver's driving habits are also different, generally every 10,000 kilometers of inspection, if the spark plug electrode surface is gray-white, clean and pollution-free, normal discharge, normal ablation, then there is no need to replace.

The replacement cycle of ordinary automobile spark plugs is about 30,000 kilometers.

Depending on the material of the spark plug, the replacement mileage also varies:

Ordinary copper core spark plug replacement mileage; 30,000 km;

Yttrium spark plug replacement mileage: 50,000 km;

Platinum spark plug replacement mileage: 50,000 km.

In the ignition system of a gasoline engine, a high-voltage current is introduced into the cylinder to produce an electric spark to ignite the components of the combustible gas mixture. It is mainly composed of a wiring nut, an insulator, a wiring screw, a central electrode, a side electrode and a shell, and the side electrode is welded to the shell.

The gap between the electrodes of the spark plug has a great influence on the work of the spark plug, and if the gap is too small, the spark is weak, and it is easy to leak electricity due to carbon deposits; The gap is too large, the required breakdown voltage increases, the engine is not easy to start, and it is easy to occur at high speed "lack of fire", so the spark plug gap should be appropriate, the spark plug gap used in the general battery ignition system is 0 7 0 8mm, and the individual spark plug gap can reach more than 1 0mm.

Summary. Hello oh kiss, the spark plug is changed once every 2-30,000 kilometers. The spark plug can be said to be the heart of the engine, without which the engine cannot operate.

The function of the spark plug is to ignite, the spark plug electrode produces a high-voltage volt, forms an electric spark, ignites the mixed gas in the engine cylinder, and burns it, thereby promoting the piston movement, and the engine runs and the car can drive. <>

Hello oh kiss, the spark plug is changed once every 2-30,000 kilometers. The spark plug can be said to be the heart of the engine, without which the engine cannot operate. The function of the spark plug is to ignite, and the spark plug seepage electrode produces a high-voltage electric volt, forming an electric spark, igniting the mixed gas in the engine cylinder, and blasting the combustion sensitive, so as to promote the bridge piston movement, and the engine will run and the car can drive.

<> dear, when the car is driven to a certain number of kilometers, the spark plug will produce carbon deposition and electrode gap increase and other faults, carbon deposition will increase engine fuel consumption, and the increase of spark plug gap will cause insufficient ignition energy to cause starting difficulties. Therefore, frequent inspection of Tongpai maintenance spark plugs can prolong the life of the engine Zhenlun Forest. <>

<> kiss the afternoon shouting quietly, the service life of ordinary spark plugs is about 2-30,000 kilometers, and the service life of *** material can reach about 6-100,000 kilometers, of course, these replacement cycles are only theories under normal circumstances, and the replacement cycle of the body depends on the actual use of the vehicle.
