Spark plugs, as one of the important components of the automotive ignition system, have the characteristics of easy wear and tear, and generally need to be replaced regularly according to the service life. So, what is the time interval between spark plug replacement?In other words, how can we tell when a spark plug needs to be replaced?This article will introduce the necessary knowledge of spark plug replacement to help you better grasp the process.
Long-term use of spark plugs, because of the consumption of electrodes, will lead to a larger gap, a decrease in ignition performance, it is not easy to produce sparks, the possibility of misfire and side ignition increases, resulting in incomplete combustion, increased fuel consumption, and decreased start-up and acceleration. If the spark plug is not replaced for a long time, it may also cause black and fouling of the spark plug, increase the fuel consumption of the vehicle, deteriorate the performance, pollute the environment and damage the engine. When the car has the above faults, it means that it needs to be replaced with a new spark plug. It is necessary to check the use of the spark plug in time and replace the spark plug according to the service cycle.
Some bad driving Xi and improper operation in daily life will also affect the life of the spark plug, resulting in the spark plug can not work before the service life, such as usually adding low-quality gasoline, long-term heavy load work of the car, often driving in poor road conditions, etc., which will cause the life of the spark plug to be shortened. If there are above bad driving Xi, it is necessary to test the performance of the spark plug in advance, and replace the worn spark plug in time if necessary. Therefore, it is best to incorporate the spark plug into the daily maintenance of the car, conduct regular testing, and develop good driving Xi when driving, which can not only reduce the occurrence of failures, but also extend the service life of the car and the spark plug replacement cycle.
The replacement cycle of the spark plug is judged according to the electrode material, the common electrode materials are nickel alloy, platinum and iridium, platinum and iridium metal have higher metal strength, better ductility and stronger chemical stability than nickel alloy, and can withstand higher temperature and pressure in the engine. The spark plug made of *** material also has the characteristics of anti-corrosion and anti-oxidation, which can prolong the service life of the spark plug. However, in order to make the life of the spark plug longer, only the use of the central electrode does not have the characteristics of long life, and the life of the spark plug is similar to that of the nickel alloy spark plug, and it is generally recommended to 1Replace it once every 5-20,000 kilometers. The spark plug used for both the outer electrode and the central electrode is a long-life spark plug, and the specific replacement mileage refers to the recommendation of the automobile manufacturer.
When replacing spark plugs, it is recommended to choose a high-quality professional spark plug brand. For example, NGK spark plugs provide spark plug matching for many automobile manufacturers around the world, and the original matching rate of NGK can reach more than 70%, covering the spark plug adaptation of most vehicles. The original series of double platinum spark plugs and iridium platinum spark plugs have fast ignition and strong power.
The service life of the spark plug is limited, and regular inspection and replacement are conducive to ensuring the stable operation of the engine. With more than 80 years of experience in spark plug manufacturing, NGK also has the advantages of ceramic technology, and produces a variety of spark plug types and a wide range of supporting facilities, which is the first choice for many cars to match spark plugs, and is also the trusted choice of the majority of car owners.
