How long does it take to change the car spark?How do you think the spark plug should be changed?The engine is the heart of the car, and the spark plug is the heart of the engine, which directly affects the acceleration performance and fuel consumption of the engine. The old driver knows that the spark plugs need to be replaced regularly. When the car appears unstable, poor acceleration or launching difficulties, then consider changing the spark plugIts right.
Spark plug
1. Specific spark plug:
The insulating body skirt is slightly shrinking into the end surface of the shell, and the side electrode is the most widely used as the end surface of the shell.
2. Progressive spark plug:
The insulator skirt is long, which is protruded from the end of the shell.It has the advantages of large heat absorption and good anti -dirt resistance, and can directly cool down the cooling and reduce the temperature, so it is not easy to cause hot hot spots, so the heat adaptation range is wide.
3. Electrical spark plug:
Its electrode is very thin, characterized by strong sparks, good ignition capacity, and can also ensure that the engine starts quickly and reliably in the severe cold season. The heat range is wide and can meet a variety of uses.
4. Seat -type spark plug:
Its shell and spinning threads are made into cone, so it can be kept well seal without the padding circle, which reduces the volume of the spark plug, which is more beneficial to the engine design.
5, polar spark plug:
The side electrode is generally two or more or more. The advantage is that the ignition is reliable, and the gap does not need to be adjusted frequently. Therefore, some gasoline engines that are easy to abract and spark plugs are often used on the electrode.
6. Face -jump fire -type spark plug:
That is, along the surface gap, it is the coldest spark plug. The gap between the electrode and the end of the shell is the same.
Spark plug cleaning
1. White vinegar cleaning
Find a glass container and put it in a spark plug, pour in ordinary white vinegar that can be over the spark plug. Note that it is white vinegar, and then it is fine. You can do something else. Generally, it is not serious about carbon.Hours, soak for 4-5 hours.
Time is here, find a hard toothbrush, and brush a few times, you will find that all the stubborn accumulation of carbon is all falling, and you will find that your spark plug is no different from the new one, hehe.Dry the white vinegar and let it be air -drying for a while, you can deliver it, but do not rinse it with water. Remember!
2. Washing solution with a carburetor
How to disassemble the spark plug is a technical job, not within the scope of this experience.Put the spark plug down in the glass bottle, spray the liquid cleaner into the bottle, pay attention to the angle, do not let it splash, soak it over the spark plug.Then cover the lid.Pay attention to fire prevention, cleaning solution is flammable substance.
Waiting for about half an hour, you will see that the liquid cleaning fluid in the bottle is getting darker and darker. Take it out of the bottle and use the carburetor to clean it with a toothbrush.Its finished.
3. Use blue toilet spirit
Use a spark plug to directly soak in the pure toilet spirit. After a while, a large amount of bubbles will be seen. This is caused by the chemical reaction of carbon accumulation after the toilet cleansing spirit.Put it in a ventilated environment for about 10 minutes. After the bubbles gradually become less, take it out. If there is still black carbon, you can soak it for a while, then rinse it with white vinegar, do not rinse with water, and then air dry.
4. Go to the 4S shop or repair shop to clean
This method is the simplest. Drive directly to the 4S shop or repair plant, and spend some money for professionals to get it.But generally it will not help you clean but replace it directly.Budget is bigger.
How long does it take to change the spark plug
1. How often does the spark plug change?
If the fuel consumption of vehicles is found, you can consider whether to change the spark plug. Generally, the repair shop will recommend replacing 20,000 to 30 kilometers, because although the spark plugs are not completely damaged, the efficiency has decreased.In fact, this depends on the quality of the spark plug. The ordinary spark plug is changed once every 30,000 to 40,000 kilometers, and the platinum and gold and gold are 60,000 to 80,000 kilometers.Generally from tens of yuan to 100 yuan.Find another reliable maintenance shop for installation. The installation process is very short. Generally, you can view it yourself. This can save money and avoid the black heart repair plant to use the half -new spark plug removed from other peoples car again.
2. How do I look at the spark plug? Should I change it?
1. Real car inspection: It is best to operate under the guidance of professionals. The owner understands that this common sense is more for identifying the maintenance of professionals. It is best not to do it by yourself.
(1) Short circuit: Let the engine run idle, use a screwdriver to short circuit to the spark plug, listen to the engine speed and sound changes, and the speed and sound changes are obvious, indicating that the spark plug is normal.When the speed and the sound are not obvious, the spark plugs are in an abnormal state.
(2) Jumping fire: Rotate the spark plug, put it on the cylinder body, and try the fire with a high -voltage line. If there is no spark or the spark is weak, it indicates that the spark plug is leaking or not working.
2. Observe the appearance color: The owner can learn this method. After the maintenance personnel disassemble the spark plug, they can make a judgment and inspection by themselves.
Remove the spark plug observation, and observe the use of the spark plug according to the following color observation:
(1) If it is red or iron rust, it means that the spark plug is normal;
(2) If it is oil -stained, it indicates that the spark plugs are disordered or excessive oil supply, and the high -voltage line is short -circuited or disconnected;
(3) If it is a smoky black, it indicates that the spark plugs are selected or mixed with cold and cold type, and the oil is rushing on the oil;
(4) If there are sediments between the top and the electrode, when the sediment is oily, it proves that the cylinder channeling oil is not related to the spark plug; if the sediment is blackIt is due to the lack of fire caused by the additive in the gasoline to cover the electrode;
(5) If the spark plug is severely abstructed, the phenomenon of scars, black lines, ruptures, and electrode melting appear at the top, which indicates that the spark plugs have been damaged and must be replaced immediately.
