The low temperature in winter makes it difficult for cars to start. Here are some common reasons and solutions:
1. Battery failure: When the temperature is low in winter, the capacity of the battery will decrease, and it will be difficult to start when the voltage is low. The solution is to replace the battery.
2. Slow flow rate of engine oil: Low temperature will increase viscosity of engine oil and slow flow rate, which will further increase engine resistance and make it difficult to start. The solution is to use special engine oil for winter in winter.
3. The exhaust pipe is frozen or the valve has too much carbon deposit: water vapor will be generated when the engine is running. If the exhaust pipe is frozen or the valve has too much carbon deposit, it will block the exhaust pipe and make it difficult to start. The solution is to let the car run at high speed, drain the water from the exhaust pipe and clean the throttle regularly.
4. Engine failure: serious engine wear, decreased sealing performance and insufficient cylinder pressure will also lead to difficulties in starting. The solution is to screw out the spark plug, wipe off the oil between the electrodes, and then put it back on.
The above are the common reasons and solutions for the difficulty in starting a car in winter, and I hope it can help you.
