There are thousands of parts in our cars, each of which is vital. However, many people only know to change the oil during the maintenance process, but ignore small parts such as spark plugs. So today I will show you how to judge for yourself whether the spark plug needs to be replaced.

Many people may not know what spark plugs are used for. In fact, this little thing is the throat of the car. If it has a problem, the engine will not fire and the car will not work. If you find that the car is difficult to start in a cold state, there is obvious frustration, idling jitter, or engine acceleration performance decline when driving, it means that there is a problem with the spark plug of your car.

There is a car phenomenon

The first is the phenomenon of engine towering. After driving for a certain distance, the phenomenon of towering when we want to upshift indicates that the engine is insufficiently powered, sometimes black smoke will appear, and fuel consumption will increase. At this time, the spark plug can no longer support the work of the engine, so it must be replaced in time.

Engine jitter

The second is that there are often very obvious engine jitters.

Of course, occasional engine jitter may not be a problem, but if this problem occurs frequently during normal driving, it is likely to be caused by aging or even damage to the spark plug. Of course, the premise is to eliminate the influence of the three-cylinder engine, and it is very common for a three-cylinder engine to experience jitter. And if it is not a three-cylinder engine model, if the engine shakes significantly, car owners should pay attention to replacing the spark plug.

Difficulty starting the car

The third situation is that it is difficult for the car to start, it turns off as soon as it starts, or it simply fails to start. Difficulties in starting a car are generally caused by the performance degradation of the spark plug. The spark plug cannot provide enough energy. If the car cannot start all the time, it is very likely that the spark plug is completely broken. But in which case, the best solution is to go to the store for a new spark plug, and the problem will be solved.

After understanding its function, let's talk about how to judge the replacement. Not every spark plug replacement cycle is completely fixed. Nowadays, the commonly used spark plugs on the market can be roughly divided into three types. Nickel alloys are mostly used in cars with around 100,000 yuan, and platinum is mostly used in mid-level and high-end cars. It is iridium, which is mostly used in luxury cars. Generally speaking, the replacement cycle of a spark plug is directly related to its material. The replacement cycle of nickel alloy spark plugs is 20,000 to 30,000 kilometers, single platinum spark plugs are 40,000 kilometers, dual platinum spark plugs are 60,000 kilometers, and iridium spark plugs are 80,000 kilometers. Kilometers, the replacement cycle of platinum-iridium alloy spark plugs can reach 100,000 kilometers.

In fact, for the improvement of automobile power performance, the more expensive the spark plug, the better. A good spark plug is helpful to the power performance of the automobile, but this kind of help also depends on the engine itself. If the engine performance does not reach a certain "level", install it. No matter how advanced the spark plug is, it will not help much in power performance.

The reality sounds so cruel. Isn't it enough to buy a good spark plug? Wipe your tears and don't panic, let the editor tell you the ultimate maintenance secret of a spark plug-using high-quality fuel, the fuel quality and the life of the spark plug are closely related. When refueling, you must not be greedy to add oil products with quality problems at a cheap price, and do not regret it later.
