What is the reason why Changan Ounuo car can't catch fire?

Seeing that it is getting colder and colder recently, the temperature is gradually decreasing, and car owners will find it when they get up early for work. This kind of car is less and less easy to catch fire, and sometimes it can only be hit several times, which is a waste of time and harmful to the car. What's going on here? Tell everyone about it!

1. Battery failure

When the temperature is low in winter, the capacity of the battery will decrease at low temperature, and the starting voltage of the battery will be lower after a period of use. Therefore, when winter comes, it is necessary to replenish the battery electrolyte in time or replace it with a new battery. If the vehicle is not used for a long time, take out the battery and put it in a warm place to avoid damaging the battery.

2. Slow oil flow rate

When the temperature is low in winter, the viscosity of the engine oil in the car will increase, and the flow rate will slow down, which will increase the resistance of the engine and make it difficult to start the car. Therefore, winter special engine oil should be used in winter.

3. The exhaust pipe is frozen or the valve has too much carbon deposit.

When driving, the engine is burning internally. After internal combustion, water vapor will be produced, which will cause condensation in a certain part. If it doesn't melt for a long time, the car will definitely be difficult to start. At this time, the car should be driven at high speed and the water in the exhaust pipe should be discharged. In addition, too much carbon on the valve is easy to block the throttle, so it is recommended to clean the throttle regularly.

4. Engine failure

When the engine is seriously worn, the sealing performance will decrease and the cylinder pressure will be insufficient, which will also lead to the difficulty of starting the car. You can unscrew the spark plug, wipe off the oil between the electrodes, and then put it back.

5. The exhaust pipe is frozen.

The water vapor after engine combustion freezes at the muffler of exhaust pipe, which often happens in vehicles with low frequency of use and short driving distance. At the same time, the damage of three-way catalysis may also cause difficulties in starting.

It's getting colder and colder now. What should I pay attention to when driving?

1. If the temperature is low, the car may not catch fire. At this time, try a few more times. If it still doesn't work after three times, wait for a while, let the car slow down for a few minutes, and stop using the electrical equipment in the car when parking!

Don't drive at high speed immediately after the car starts. Be sure to warm up for a minute or two. Just start using the lowest gear to adapt the car and improve fuel economy.

3. Carbon deposition will reduce the engine power and increase fuel consumption, so it is necessary to check the engine carbon deposition regularly and clean the oil circuit carbon deposition in time;

4. It is recommended to do a professional winter maintenance in winter and replace the appropriate engine oil suitable for the local climate.

Here, I tell you, in the coming winter, take your car for a comprehensive maintenance and take good care of your car, so there won't be so much trouble!
