What should I do if the car doesn't burn because the car tank is frozen in the cold morning? what can I do?

The gasoline in the tank is frozen, so you can add some gasoline pour point depressant.

Usually, the content of n-alkanes in gasoline is about 15% ~ 30%. When gasoline is cooled, as long as about 2% of normal alkanes are precipitated, gasoline can be solidified.

The wax precipitation of gasoline at a certain temperature depends on the type of crude oil, distillation range, processing scheme and blending ratio of each fraction of blended gasoline.

Adding pour point depressant can change the shape or size of wax crystal. Therefore, under the action of pour point depressant, when the temperature of gasoline drops to near the cold filter point, a large number of fine wax crystal particles will appear in gasoline, which will make the appearance of oil products turbid, thus reducing the cold filter point and freezing point of gasoline.

Precautions for cars in winter:

1, to prevent the windows from freezing.

You can open the door or window before leaving the vehicle, so that the air inside and outside the vehicle can convect for a short time, and avoid the icing phenomenon caused by the residual water vapor inside the vehicle.

Don't park your car in the snow or puddle.

Pay attention when parking. It is best not to park your car in the snow or puddle, because the temperature is low at night, and it is very likely to "freeze" your car the next day. This is not only harmful to the car, but also delays the working hours.
