What is the reason for the sudden flameout of the car?

Cause of flameout: \r\n 1. Automatic transmission models: \ r \ Automatic transmission models will not turn off easily, while manual transmission models may turn off frequently due to poor driving level. However, it is not excluded that automatic cars will not stall. The main reason is the use of inferior fuel (many gas stations sell impure oil for profiteering), which leads to carbon deposition and flameout of the engine. \r\n2。 In addition, for new cars (automatic transmission), flameout is mainly caused by poor driving skills. Another possibility is the problem of the engine or the oil circuit, but for a new car, the problem of the engine itself is less likely, and most of the reasons are oil circuit problems. \r\n3. Finally, for the old models, the reason of flameout is not only the lack of skilled driving skills, but also the carbon deposition caused by the use of unqualified engine oil. \ r \ nTroubleshooting of automatic transmission: \ r \ nWhat should be paid attention to at ordinary times: The flameout of automatic transmission is mainly caused by using inferior fuel. First, go to a regular big gas station to add high-grade oil, such as 97 # gasoline. Although the price is much more expensive, it can guarantee a longer life and good driving force. But there are also car owners who are greedy for cheap and 90 # oil. Although the price is lower, problems may arise in the future. The second is to go to a large qualified gas station to refuel! \ r \ Practical operation: Hold the steering wheel steady with your left hand (because there is no power, it must be steady), step on the brake with your right foot to reduce the speed as much as possible, and then quickly shift the AT gear to the N gear (note: the reignition must be in the N gear, not in the D/R/P gear, otherwise the car will not catch fire or the gearbox of the car will be damaged), and then retreat the key by one space. \r\nManual gear failure: \r\n 1. For novices, stalling in the middle is not a new topic. The main troubleshooting method is to improve driving skills after running in quickly. \r\n2。 Use high-quality qualified fuel. \r\n3. Thoroughly clean the oil circuit, including the fuel injector, throttle valve and fuel tank. It may be that the quality of the oil you added is not up to standard, and there is too much gum, which blocks the oil circuit and leads to poor oil output. \r\n4。 There is too much dust in the air. When the engine is running, a lot of dirt is deposited on the spool and throttle seat of the idle motor. When the dirt accumulates too much, the engine will have low idle speed, poor idle stability and idle flameout when driving. The solution to this problem is simple: just clean the idle motor. \r\n5。 Whether the oil circuit is smooth or not can easily lead to flameout in the middle. \r\n6。 Due to the rising oil price and the fact that many people like to go back-more people ride bicycles and walk to work, the new car has been idle for a long time. Actually, don't park for a long time. If it is parked for a long time, it should be thoroughly maintained, the oil and filter should be replaced, and the fuel and circuit should be checked as appropriate. Due to long-term parking, your vehicle may have lubrication or circuit problems. \ r \ nIn a word, whether it's a new car or an old car, whether it's an automatic transmission or a manual transmission, whether it's a veteran or a novice, you should improve the grade of oil when refueling, even if it's expensive, so as to protect your engine from carbon deposition. In addition, regular maintenance is also very important. Always check whether the oil circuit and circuit are unblocked. \ r \ Some friends complained that the cold car wouldn't light. Let me talk about the general diagnosis to prevent being killed by JS. First of all, eliminate the problem of no oil and no electricity ~ ~ ~ Hehe, needless to say, there are two situations: 1 > it can't start at all, usually the temperature sensor is short-circuited, broken or damaged; Another possibility is that if you are really unlucky, there is something wrong with the ECU. 2 > call several times. If there is nothing wrong with the hot car running, it is generally that the temperature sensor is in poor contact, so just plug it tightly. If the hot car finds that the car is weak but the exhaust is normal, it means that the engine is panting and the nozzle is blocked. It is recommended to check and clean it up. If the hot car finds that the exhaust gas is black, the fuel consumption has increased recently ~ ~ ~.
