Before I talk about gasoline filters, I want to talk about the quality of gasoline. Iraq's oil field is very famous. The crude oil is better. At the same time, the crude oil wax content is 0.9% by measuring the temperature of - 30 ℃. That is to say, the low wax content of gasoline represents the composition of long carbon chain, including less gasoline, including more long carbon chain composition, insufficient combustion, and easy carbon deposition in the engine; The wax content of crude oil in China is about 15% ~ 20%, that is to say, a good gasoline filter is very important under the condition of poor automobile environment in China.
Most people know that gasoline filter can filter out impurities in gasoline. Because the modern automobile uses the electric injection type oil supply, the oil pressure is big, so now the petrol filter shell uses the packing, but the internal material is composed of the filter paper, the better petrol filter has the nylon material or the high polymer material.
Change the oil every time you go for maintenance. Semi synthetic oil is used for the following models, and the mileage is 7500km according to the maintenance cycle. However, this guy only changed the oil after 7800 km. When the oil is put in, we can clearly see the color of the yellow oil after 7800 km. The engine oil can play the role of sealing, lubrication, cooling, decontamination and so on. The key is lubrication.
Let's look inside the oil filter. Most oil filters use paper filters to filter oxides and other impurities generated during engine operation. When oxides and impurities are attached to the oil, oil filter is required for filtration. After filtering a large number of impurities in the oil filter, the filter paper will be blocked. At this time, the filtering effect is greatly weakened and needs to be replaced. Does it affect the engine?
If we only change the oil filter instead of changing the oil, it will not have any effect, because the oil cleaning function is very important. In addition to lubrication, the oil filter is "polluted". The oil passing through the filter is also polluted. The engine is also good if it is lubricated with impurities.
By comparing the new and old oil filters, we can clearly see the difference between the new filter and the new filter after 7800 km. From the black oil filter, we can see that the oil has been very poor, the oil flow is not good, and the viscosity is large, which hinders the work of the engine piston. In addition, if the resistance is large, the oil flow will be less, and the lubrication effect will be reduced.
If the hybrid (poor oil and gasoline) burns for a long time, it will affect the engine. Changing the oil filter can effectively solve this problem, and the cost of changing the oil filter is not high.
Air conditioning filter
In spring, many people have colds and fevers. It is generally believed that the body is not suitable for the transitional season, but have you ever thought that the air conditioning filter net causes the bacteria attached to the air conditioning filter to grow for a long time after a winter without using the air conditioning filter. After the air conditioner is put into use in spring, the air conditioner directly blows the bacteria to the passengers in the car. The whole car is a breeding ground for bacteria.
The main function of the air conditioning filter is to filter the air impurities in the car, but the air conditioning filter has a certain replacement cycle. When the air conditioning filter is full of adsorbed impurities, the air conditioning filter will lose its filtering effect. If you turn on the air conditioner at this time, the impurities attached to the air conditioner filter will not be blown into the car, whether it is bacteria or dust, I think the passengers in the car are uncomfortable.
