As the necessary consumables for gasoline engines, spark plugs affect power output and carbon deposits to a certain extent.IntersectionChoose spark plugs from the aspects of size, heat value, material, structure, and brand.Spark plugs must choose the size, length and diameter that suits your own vehicle.In addition, you must choose according to the thermal value that matches the vehicle. If you choose not to match, it will affect the performance of the engine.Let ’s take a look with Xiaobian.
How much it is appropriate to spark plugs
1. How suitable is the spark plug space?
The spark plug gap used in the general battery ignition system is 0.7 to 0.8mm, and the gap between individual spark plugs can reach more than 1.0mm.
The gap between the spark plug electrode has a great impact on the work of the spark plug. If the gap is too small, the spark is weak and it is easy to leak electricity due to the production of carbon deposits; the gap is too large, the required breakdown voltage increases, the engine is not easy to start, and at high speeds at high speedThe phenomenon of "fire lack" is prone to occur. Therefore, the spark plug gap should be appropriate. Generally, the spark plug used in the battery ignition system is 0.7 to 0.8mm, and the spark plug gap can reach more than 1.0mm.
2. Spark plug gap standard
Spark plug gap: Mainly refers to the distance between the electrode of the spark plug center and the ground electrode.
Small gap between spark plugs: When the gap is too small, it is very easy to produce carbon deposits and cause leakage.
The gap between the spark plug is too large: When the gap is too large, the breakdown voltage will increase at this time. At this time, the engine is not easy to start.During the high -speed driving process, it is prone to fire shortage, and the arc will become longer and longer make the mixed gas in the cylinder easier to ignite.At this time, the kinetic energy provided is also very large. At this time, the voltage required must be large, and the gap is not suitable for any model.
3. Species of spark plug gap standard selection
There are big and good, small and small, and different models are different.The gap in general use is 0.7 ——0.8mm, and many spark plugs can reach more than 1mm.The spark plugs used in SUV, MPV, and pickups are very large. Micro -cars, compact cars, and micro -surfaces are all selected standard forms.
Spark plug accumulation carbon
1. Several symptoms of spark plug accumulation
1. Cold cars have been ignited many times, and hot cars are normal.
2. The engine idle speed is unstable, and the high and low speed.
3. When adding oil, it feels poorly accelerated and has the phenomenon of dullness.
4. The powerless driving is especially reflected in the overtaking. The speed -up response is slow and cannot achieve the power of the original car.
5. The tail gas is very dazzling, pungent, and serious.
6, fuel consumption is increased than ever.
Second, the removal and maintenance method of spark plug accumulation
The key to dealing with spark plug accumulation is to prevent and clear regular maintenance, so as to keep the oil roads and gas roads as clean as possible; clean the air grid every 4000-8000km (according to the use of the vehicle)Through the throttle, clean up the fire mouth, put the spark plug off in the plastic or paper cup, and then use the UD Youdao spark plug carbon cleaner to soak it in the cup for 5-8 minutes to safely remove the carbon accumulation on the spark plug.And it does not hurt the spark plug metal parts, safe and non -corrosive, so that the engine ignition performance is improved, and it is ensured that the engine work is normal.Clear spark plug accumulation can improve car -loving horsepower; save fuel consumption; reduce explosion points; promote environmental maintenance; extend the engine life; strengthen the accuracy of braking braking.Tip: According to the use of the vehicle, the formation of carbon accumulation is also different. Generally, the selection mileage of UD Youdao spark stuffed carbon cleaning agent is used in 20,000 to 30,000 kilometers to clean.Carbon deposits are not terrible, and we are afraid that we will not control it.
Spark plug maintenance
1. Replace the spark plug in time according to the type
How to determine the life of the spark plugs to be replaced? Whether the spark plug needs to be replaced and removed, you can see it. Look at the color of the burning color, the gap between the electrode, whether the gap between the porcelain and the metal shell is leaking, and so on.If the owner finds that it is difficult to start in a cold car, when driving, there is a clear sense of frustration, idling jitter, or a decline in engine acceleration performance.Because once the vehicle appears above, it may be caused by the aging of spark plugs.
2. Choose to be targeted
In fact, the improvement of automotive power performance is not the more expensive the spark plug.Good spark plugs are helpful for improving automotive power performance, but car owners cannot have too high expectations for this help, and the help of spark plugs for power performance depends on the engine itself.Putting on high -end spark plugs will not help improving power performance too much.However, Mr. Fang does not have to be upset for himself as a "grievance".Although good spark plugs do not have significantly improved the power performance of all engines, long -term use will definitely reduce the use of engine carbon deposits, extend the service life of the engine, and also help fuel saving.
3. It is not difficult to clean the spark plug by yourself
The maintenance should first clean up the air filter to prevent the dust from entering the combustion with the mixed gas, so as to prevent the spark plugs from being corroded.Secondly, the owner can also remove the spark plugs by themselves to clean up the dirt and carbon deposits on the ignition head.It is important to note that when disassembling spark plugs, pay attention not to let the dust enter the cylinder when the spark plug enters and exit. When removing the spark plug in advance, clean the surroundings.If there is oil in the cylinder, the piston ring or other components should be replaced in time to avoid short circuit caused by the spark plug accumulation of carbon.In addition, fuel oil and oil products are also closely related to the life of spark plugs. Therefore, the owner must pay attention when refueling, and should not be greedy for cheap oils to add quality.
