What to do if the car can’t catch fire in winter, clean the spark plug by yourself

【The owner's family car knowledge】With the advent of winter, as the temperature continued to drop, some minor problems with the car began to show up. Recently, Mr. Zhang, who lives in Shuangliu, called the hotline and said that in the past week, he found that it was very difficult to get in the car in the morning, and sometimes it took several calls to call. At the same time, abnormal noises can often be heard during the driving process. To this end, our reporter contacted Lu Jingen, a senior automotive after-sales service expert, and asked this question. He suggested that car owners should first check the spark plugs if they encounter difficulties in the winter. Because the spark plug is the key to the automobile ignition system, and the ignition system is the key point of the engine, therefore, the performance of the spark plug is related to the working performance and efficiency of the vehicle. How to choose the right spark plug and when to replace it? How to maintain the spark plug to make the engine more "powerful"? Now we will answer you one by one.

The resistance spark plug needs to be replaced for 20,000 kilometers

Spark plugs are a major component in the ignition system of automobile engines. All gasoline engines have spark plugs, one for each cylinder, and individual high-speed gasoline engines are also equipped with two spark plugs per cylinder. The function of the spark plug is to introduce the high-voltage electricity generated by the ignition coil into the engine cylinder, and generate a spark between the spark plug electrodes to ignite the mixture.

Lu Jingen told reporters that currently commonly used spark plugs are divided into resistance spark plugs, polkin spark plugs and iridium spark plugs. Generally speaking, the life of resistance spark plugs is 20,000 kilometers, the life of Bourkin spark plugs is 40,000 kilometers, and the life of iridium spark plugs can reach 60,000 to 80,000 kilometers. Therefore, the original spark plugs of low-end cars are generally resistance spark plugs, while the original spark plugs of luxury cars and mid-to-high-end models are mostly iridium spark plugs.

How to determine the service life of the spark plug should be replaced? Lu Jingen said that if the spark plug needs to be replaced, you will know if you remove it and check it. Look at the burnt color, the electrode gap, and the gap between the porcelain body and the metal shell for air leakage. and many more. In addition, he also said that if the car owner finds that the car is difficult to start in the cold state, there is obvious frustration, idling jitter when driving, or the engine acceleration performance decreases, the spark plug should be checked in time. Because once the vehicle has the above-mentioned performance, it may be caused by the aging of the spark plug.

Spark plugs are not as expensive as possible

Regarding the topic of "difficulties in driving in winter", the reporter immediately launched an investigation on the website of a car club. Among them, the owner of the car, Mr. Fang, said that last month, when his car was replaced with the original spark plug after driving 20,000 kilometers, I heard from friends that the iridium spark plug can improve the dynamic performance of the car, and I also feel that after 20,000 kilometers, the acceleration performance of my economic car has declined, so I can’t resist the temptation and spend a “big price” on it. My car was replaced with a set of iridium spark plugs. After the replacement and use, he felt that the acceleration performance of the car had not improved much, and he called himself a victim and was deceived.

Regarding Mr. Fang’s "dang", Lu Jingen said that in fact, for the improvement of automobile power performance, it is not that the more expensive the spark plug, the better. A good spark plug is helpful to the power performance of the car, but the car owner cannot have too high expectations for this help, and the help of the spark plug on the power performance also depends on the engine itself. If the engine performance does not reach a certain "level", Even more advanced spark plugs will not help the power performance much. But Mr. Fang doesn't have to be injustice because he is being taken advantage of. "Although a good spark plug can't significantly improve the power performance of all engines, long-term use will definitely reduce engine carbon deposits, extend engine life, and also help to save fuel." Lu Jingen said .

It's not difficult to clean the spark plug, the owner can do it himself

When the car travels to a certain number of kilometers, the spark plug will generate carbon deposits and the electrode gap will increase. The carbon deposits will increase the fuel consumption of the engine, and the increase in the spark plug gap will cause difficulty in starting. Therefore, frequent inspection and maintenance of spark plugs can extend the life of the engine.

Lu Jingen suggested that car owners should clean the air filter regularly for maintenance to prevent dust from entering and burning with the mixture, which can prevent the spark plug from being corroded. Secondly, the car owner can also remove the spark plug by himself to clean up the dirt and carbon deposits on the ignition head. It is particularly important to note that when disassembling the spark plug, be careful not to let dust enter the cylinder when the spark plug is in and out, and clean the surroundings before disassembling the spark plug. If there is organic oil in the cylinder, the piston ring or other parts should be replaced in time to prevent the spark plug from depositing carbon and causing the electrode to short-circuit. In addition, fuel oil is also closely related to the life of the spark plug. Therefore, car owners must pay attention when refueling, and should not be greedy to add oil with quality problems at a low price.
