Guo Si Jianghuai Kang Ling can't afford to drive in winter.

It's just a matter of low temperature. Winter is cold and the temperature is low. The car will take a little longer to start than usual.

Especially for cars that have been used for many years, there will be symptoms of difficulty in starting.

Generally, driving in winter must be hot first! ! This is an important step, but many people will deliberately ignore it.

We also talked about this problem in the program of Xingshang!

First of all, warm-up in winter can prevent the internal parts of the engine from wearing out. One of the warm-up processes is to wake up the engine oil that has been' quiet' all night and let them lubricate some parts in the engine first. We have also met too many users who started it because they didn't warm up for a long time, resulting in the wear of connecting rods and crankshafts! Finally, only those accessories can be replaced.

Also, many people have a bad habit, that is, turn on the air conditioner when heating the car and raise the temperature inside the car by the way. In fact, this hot car method is not recommended. It's best to turn off the air conditioner when the car is hot, and let the engine idle at 1000 rpm or below. When the car is hot, turn on the air conditioner, and the air conditioner temperature will increase obviously after the water temperature rises. Otherwise, even if the air conditioner is turned on, the temperature inside the car will not be greatly improved, but it will bring extra burden to the compressor.

The general reason why the car won't start is that there are no season and weather factors here!

1, the water temperature sensor is broken.

2. The throttle is dirty. Cleaning the lower throttle assembly is generally possible.

3. The ignition efficiency of spark plug, ignition coil and cylinder pipeline is too poor. This can only be replaced by accessories.

4. Dirty intake flow sensor, carbon deposit in intake pipe, carbon deposit in valve and carbon deposit in combustion chamber will all lead to this problem.

5. It is possible that mismatched engine oil is used, the viscosity exceeds or the engine oil used can't keep up with the level required by your car.

6. The exhaust pipe and oxygen sensor are damaged and the three-way catalyst is blocked. Poor exhaust can also cause this problem.

7. If the atomization of the fuel nozzle is not good, ultrasonic cleaning will generally occur in 20,000 kilometers. If it doesn't work, it should be replaced.

8. The fuel filter is blocked and cannot reach the pressure of the gasoline pump.
