The car won't start in cold weather.

The reasons why the car won't start in cold weather are as follows: 1. Battery problem, 2. Oil and gasoline problems. Knowing the reason why it is difficult to make a fire can "prescribe the right medicine". Generally speaking, the faster way is that we can start together with the help of the throttle, but we must find the real root of the problem afterwards to solve it.

Low temperature makes it difficult for vehicles to ignite:

(1) Battery problems, and cold weather will reduce the energy of automobile batteries. Because the electrolyte in the battery will react chemically, and the working temperature of the battery is generally between -1 and 5 degrees. If the temperature is too low, the activity of chemical components will decrease, the reaction speed will slow down, and the energy generated will decrease accordingly. In addition, at low temperature, the viscosity of electrolyte increases and the resistance increases, thus reducing the power output. At this time, it is difficult for the starter to drive the engine. At the same time, with the decrease of the voltage at both ends, the ignition power of the spark plug becomes weak.

(2) the problem of oil and gasoline. At low temperature, the viscosity of lubricating oil will also increase, which means that the fluidity of oil becomes worse. Lubricating oil should help the engine run, but this situation will make the crankshaft unable to reach the speed required for starting, and there will be resistance when the engine starts, making it difficult to run. Gasoline has the same experience. When the air temperature of the engine is low, the heat absorption will affect the temperature of the mixture, causing most of the fuel to enter the cylinder in liquid state, causing the mixture to be too thin to start.

how to solve it: if you know the cause of the fire, you can "prescribe the right medicine". Generally speaking, the faster way is that we can start together with the help of the throttle, but we must find the real root of the problem afterwards to solve it. The service life of the battery is 2-3 years. If it expires, replace it, or use an automobile battery with the same nominal voltage. When the temperature is low, try to use low viscosity oil to ensure the quality of lubricating oil and engine oil; Air intake and exhaust system and fuel system, go to regular 4s shop for cleaning and nursing on time, and don't disassemble them at will; Go to the repair shop to test the parameters of various electrical indicators; For the fault problem, either repair or replace it. In addition, cold start liquid can be used appropriately. When it is difficult to start the engine in winter, spray the starting fluid into the cylinder. Remember not to abuse and rely too much.

note: it is normal to start a fire when the weather gets cold. Owners should not be too hasty. If the first ignition is not completed, do not keep turning the battery. Please wait a minute and try again.
