What are the precautions for driving in dusty weather?

First, do not use external circulation in sandstorm weather. The external circulation mode of air conditioning system is to inhale air from outside the car, and then cool or heat the air and blow it into the car. Generally, vehicles are equipped with dust filters at the air intake to purify the air. In sandstorm weather, a lot of dust is blocked at the dust filter. After the sandstorm, the car mainly cleans the dust in the dust filter, increases the air intake and makes the air inside the car fresher. For vehicles without dust filter, when driving in sandstorm weather, the frequency of using external circulation mode should be reduced as much as possible to avoid a lot of dust entering the vehicle.

Second, clean the air filter after the sandstorm. The function of the air filter is to filter the air sucked into the engine, prevent foreign objects from being sucked into the engine, and prolong the service life of the engine. In sandstorm weather, there will be many times more dust in the air than usual, and a large number of dust particles are attached to the air filter of the car. After the sandstorm, the owner should clean the air filter in time, which can not only effectively reduce the probability of dust entering the engine, but also greatly help to reduce fuel consumption.

Third, clean the water tank after the sandstorm. In spring, there are many sandstorms and catkins. After the dusty weather, a lot of dust and catkins will gather in the condenser and water tank of the vehicle, which will affect the gas flow rate, make the heat dissipation effect worse, and correspondingly increase the water temperature of the vehicle. In summer, due to the poor heat dissipation of condenser, it will also cause failures such as poor refrigeration effect of air conditioner or high water temperature. Therefore, in dusty weather, we can't ignore the cleanliness of the water tank. We suggest that you check whether there is dust and sundries on the surface of the vehicle condenser and water tank before using the air conditioner, and clean them in time to avoid affecting the normal heat dissipation of the engine and air conditioning system.

Fourth, choose high-quality engine oil, preferably similar to Kun? Lun operation? The reason why KR9-T series high-performance engine oil is slippery is that high-quality engine oil can bring carbides, sludge and worn metal particles on engine parts back to the engine oil tank through circulation, and through the flow of lubricating oil, the dirt generated on the working surface of parts is washed away, thus reducing the wear on the engine and prolonging the engine life.
