Correct methods of cold start and ignition in winter.

1. Before starting, turn on the ignition switch, wait for about 5 seconds and let the oil pump work before starting. After starting the engine, it is best to turn on the lights, radios and other electrical equipment. Before parking, turn off these power-consuming electrical facilities and then turn off the engine.

2. Some impatient drivers will start the car continuously if they can't catch fire in winter, which will do great damage to the battery and can't start the car. The correct way is: when the first start does not catch fire, start the second start after an interval of 20 seconds. Don't drive in a hurry after starting. Add a warm-up time. Generally, the water temperature of vehicles reaches 40 degrees, which is the most economical.

3. Car batteries usually discharge after parking at night and can't be started the next morning. It is suggested that the driver turn on the air conditioner, radio and other electrical appliances after the car starts the engine to warm up. Turn off the electrical equipment in time before parking, and then turn off the engine.

4. Also, don't rush to drive at high speed after the car starts, but give the car a warm-up time, so that the car is not easy to wear and tear, and it can also improve fuel economy.

5. Due to the cold weather in winter, the volatility of gasoline is reduced and it is not easy to ignite. Generally, cars will increase the starting time more or less. It is suggested that some old cars use high-grade gasoline. High-grade gasoline has low temperature, good volatility and good starting performance. Economically, it is not necessarily more expensive than low-grade gasoline.

6, low-grade gasoline in the cold temperature, the combustion quality is not as good as high-grade gasoline, heat loss. Another reminder, when we turn on the internal circulation of air conditioner in winter, we should pay attention. You know, internal circulation is to treat the air in the car and blow it into the car. In this case, the air quality is not good. If the oxygen content is too low, the driver in the car will feel very tired. In this case, it is not safe to drive. I suggest you start the internal circulation for a while, and then open the external circulation to update the air.
