How to replace spark plugs
Every gasoline engine has spark plugs, a cylinder has one, and individual high - speed g gasoline engine have two spark plugs per cylinder. The spark plug is only a small part, but it is so important parts in the ignition system. Spark plugs are consumables, yet most drivers pay little attention to such a common part. As the core of a car engine, the performance of spark plugs can almost directly determine the car’s performance, so we recommend you often check your car's spark plugs. How to judge the spark plug life Spark plug is an essential part of the normal operation of the engine. After the mixture is sucked into the cylinder and compressed, it must be ignited by the spark plug to complete the work. Therefore, to a certain extent, the performance of the spark plug will directly affect the ignition explosion of the mixture. However, the spark plug electrode will also be consumed during the ignition process. Depending on the melting point, hardness and other factors of the electrode material, the electrode will be gradually consumed. When the electrode gap is too large, the vehicle will appear power decline, hard cold start, increase in fuel consumption and other problems, then it is best to consider the replacement of spark plug. Generally speaking, the normal service life of the spark plug of the family car is about 20,000 kilometers. In addition, to extend the durability of spark plugs, some manufacturers use precious metals such as platinum and iridium in the electrodes, as well as the strength of the ignition energy.
