Is it easy to miss the bus in winter?

After the cold weather, the phenomenon that cars can't catch fire will become more and more serious. Especially when the car is older. Some people have to fight several times before they can fight, and some people just don't catch fire, which is a mess. First of all, be careful not to catch fire. Do not ignite for more than 5 seconds at a time. If it doesn't take 5 seconds, unlock the key and re-ignite. Don't keep pulling out your keys before the car hits. If you miss three times in a row, you'd better wait for half an hour before igniting. Because the current is very large during ignition, it will burn out the starter and circuit, so excessive instantaneous discharge will shorten the battery life, wait for 30 minutes, and restore the battery power.

It's cold, so it's not easy to catch fire. Most vehicles are caused by carbon deposits. This is the most common reason. Do this when you light the fire. If you don't ignite twice, it's easier to put down the throttle for the third ignition or step on the throttle repeatedly when igniting. Because the number of starts is more, the remaining gasoline in the cylinder can't be discharged. Even if the vehicle is not faulty, there is gasoline residue in the cylinder, and the mixture is too thick to get on the bus. Therefore, stepping on the accelerator can increase the intake air and reduce the concentration of mixed gas.

If you step on the accelerator and ignite, you can confirm whether it is carbon deposition in solar terms. You can ignite immediately without stepping on the accelerator. In other words, this is carbon deposition in solar terms, so clean the throttle. If there is carbon deposit, it can be solved by washing, and the parts may be damaged and can only be replaced. Generally speaking, if the following components fail, it may be difficult to catch fire. The failure of throttle or idle motor is similar to the cause of carbon deposition. It can't adjust itself after failure, and the ignition and non-ignition States are the same. The air during ignition can only enter the reserved hole of the throttle or enter from the idle motor. Because they are broken, you can't adjust the inhalation, the performance fee is wrong, and you can't get on the bus.

The gasoline pump is damaged. The gasoline pump can't work, gasoline can't enter the cylinder, naturally it can't ignite, and it can't work normally. The life of gasoline pump is very long. Generally, the problem of using gasoline pumps for more than 5 years can be considered. The method of checking whether the gasoline pump is damaged is simple. Just press the oil pressure check area on the gasoline track to see if the gasoline is ejected or connect the gasoline pressure gauge to confirm the oil pressure. Water temperature sensor. After the water temperature sensor is damaged, the signal sent to the computer is very low, tens of degrees below zero. Then the engine computer will increase the injection quantity at the time of ignition, so that the mixture is too thick to get on the bus. Of course, this situation is rare. In fact, sensor failures usually show a fixed temperature, but the temperature is not so low that it has no effect on ignition.
