Sometimes a car has to catch fire twice. What is the reason?

This question is complicated and complicated, simple and simple, so complicated that you don't know what's going on at all, so simple that you can't think of it. Tell me about my experience. After the first maintenance, the second ignition occurred the next day. I didn't care at first, but then I thought about it. It has been maintained for two months, but I didn't remember it at that time. According to the general situation, I changed the spark plug, changed the gasoline filter, changed the 4s shop and cleaned the throttle, but the nozzle didn't work, it was still the same. The elimination method used at that time almost planned to buy a gasoline pump, because I always used up the oil before refueling. Although I don't believe that the gasoline pump will break down, I want to try, but I didn't buy it. Then one day, I passed an auto parts store, and I said I would try it one last time. If it didn't work, I changed the gasoline pump, so I bought an oil filter and installed it, and the result was good. In the future, I will do everything at once. Now it is better to use up the oil before adding it, and bring your own filter element when maintaining it. Therefore, this problem should be solved by elimination method, and the possibility of the circuit is relatively small, either the gasoline oil circuit or the engine oil circuit. If the gasoline pressure comes up after turning on the switch, it needs secondary ignition, which is the problem of the oil circuit. If the gasoline pressure is released after ignition and it needs to be ignited again, it is a problem of the gasoline circuit. If you can't call all the time, you can call occasionally or all the time. If you can't call occasionally, it may be a circuit problem.

A driver friend got up to take a taxi and found that he couldn't get on the bus. When he opened the front hatch, he found that the battery observation port of the car was green. Why can't the car start? I went to the 4S store to find out why. As a result, the master of the 4S shop directly suggested replacing the battery, but the owner's friend was unhappy. Didn't you tell me that as long as the electric eye is green, it means the battery is good? It's too cheat people to ask for a replacement now. After that, I was brought back. Let's see how we got it back.

In fact, the battery's electric eye is green, but the surface battery has electricity. As for how much electricity the battery has, special tools are needed to measure it. Just like the dry battery commonly used in life, when there is electricity but it is insufficient, if it is put in the walkman, you can generally listen to radio music instead of listening to tapes. The batteries in the car are the same. The electric eye is green. From the voltage point of view, any voltage from 12V to 2V is possible, but the starting current may not be enough. If the voltage is lower than 12V too much or the starting current is too small, the car cannot be started.

Conclusion:

The battery eye is green, and the measured voltage is not lower than 12V, which does not prove that the battery is good. It needs to be tested with special equipment, such as VAS5097A.

Suggestion:

Do not overcharge or overdischarge the battery for a long time. Check the battery once a year and replace it every 2-3 years.
