What should I do if it is difficult to start the car in winter

The solution to the difficulty of igniting the car in winter and the difficulty of starting:

1. The battery power is insufficient. In winter, the power consumption of the car is higher than in other seasons, mainly because of the decrease in temperature that leads to the decline of battery capacity, coupled with the long-term operation of the air conditioner in the cab, etc., it is also very simple to solve, pay attention to the battery power every day, and charge it in time.

2. The oil flow is not smooth. In winter, especially in the northern region, the temperature is abnormally low, the viscosity of the engine oil also increases, and the fluidity decreases, resulting in an increase in the resistance of engine pistons, crankshafts and other components, which is the main reason for the difficulty of starting in winter. The solution is to heat up the engine, and if there is a sun, move the car to the sun and start it after a while.

3. The exhaust pipe is not smooth. The throttle has accumulated a large amount of carbon deposits due to long-term use, and the exhaust pipe is frozen, because the exhaust gas has water vapor after combustion, and when the temperature is low, it will freeze on the exhaust pipe, resulting in poor exhaust pipe. The solution is to place the car in a warm place after the vehicle is stopped to prevent the moisture from the exhaust pipe from freezing, and to develop the habit of cleaning the exhaust pipe.

4. The function of the automotive electronic throttle valve is to control the amount of air entering the cylinder, thereby generating negative pressure. Since the fuel cannot be completely burned in the cylinder, a lot of carbon particles will be left after combustion, and over time carbon deposits will be generated, and as the engine temperature decreases, these carbon deposits will adhere to the throttle, so the performance of the throttle will decline. As the temperature decreases in winter, it is recommended that car owners periodically clean the electronic throttle to completely eliminate the unstable idle speed and increased fuel consumption caused by carbon accumulation on the throttle.

What is the reason for the difficulty in starting the car in winter? Both new and experienced drivers need to know.

Hello, too much carbon deposition in the engine, too much dust on the throttle, it will also lead to, it is recommended to clean the throttle, carbon deposition, thank you, thank you for your support to the car master, I wish you a happy life.

Many car owners have encountered the situation of fire difficulties in winter and don't know what to do, so how to solve the car fire difficulties in winter?

1. The difficulty of ignition may be that there is a problem with the battery, especially when the temperature is relatively low, the power consumption of the car will be several times that of other seasons, and the life of each battery is about 2 or 3 years.

2. Replace with gasoline with low viscosity. Because the fluidity of gasoline with high viscosity will decrease in winter, which will lead to an increase in engine resistance and make it difficult for the car to start cold, at this time, the car mainly chooses gasoline suitable for winter, such as 5w or 0w.

3. Clean the fuel injector in time. In the process of driving, a lot of dust will enter the fuel injector and adhere to its surface, affecting the normal operation of the fuel injector, resulting in poor atomization of gasoline and delayed ignition, making it difficult for the car to ignite. The owner should clean the gum on the surface of the fuel injector every once in a while to avoid clogging.

<> "The problem of engine oil: due to the relatively low temperature in winter, our oil flows very slowly, and the viscosity will become high, in this case, it is very difficult for us to start the vehicle, we need to warm up the car for a few minutes before driving, which will be better; Especially in the Tohoku region, it is recommended to warm up the car before driving.

Insufficient power: In winter, when the hail bench comes, our car has difficulty in ignition, which is likely to be caused by insufficient battery power, we need to charge the battery, and then we can light it after the battery is charged; After that, we have to drive the car to the 4S shop to repair it and see if we need to replace it with a new battery.

Ignition system failure: If there is a problem or aging of the ignition coil or spark plug of the car, it will cause it very difficult to ignite the car, and we need to go to the repair shop or 4S shop to replace or repair Jingling parts.

The reasons for the difficulty of automobile ignition are: 1. The ignition energy of the spark plug is weak, 2. The car has carbon deposits, 3. The battery loses power, 4. The exhaust pipe is blocked, 5. The low pressure of the fuel circuit is insufficient, and 6. The engine timing is wrong. Damage to the ignition coil will also cause the engine to fail to ignite or be difficult to ignite, and it needs to be replaced in time.

The solution to the car electronic ignition is as follows:

1. Check the status of the battery, most of the difficulties in starting the car in winter are caused by the loss of battery power or the expiration of the battery service life. When the battery is low, the speed is weak when starting the car, and only the clicking sound is heard, and the clicking sound will gradually become a clicking sound when the ignition is lit again. Do not ignite continuously to avoid the battery running out;

2. Change the appropriate engine oil, in winter, as the temperature decreases, the viscosity of the engine oil will increase, and the oil flow will be difficult, so that the engine resistance will increase. If it is difficult to start, please check whether the oil label is incorrect;

3. Replace the spark plug in time, the spark plug is easy to cause carbon deposition, leakage, excessive gap, ablation and other problems after a few years of use, which will cause difficulties in car ignition, cold start, and even hot engine start, and often need to be ignited many times. Therefore, when driving to a certain number of kilometers or feeling that the vehicle is difficult to start, weak, shaking, increasing fuel consumption, or inexplicably stalling, please check the spark plug status and replace it in time.
