Speaking of Auto Oil Filter, many car owners don't pay much attention to it, because the replacement frequency of Auto Oil Filter is not high. Many drivers may not have changed the Auto Oil Filter for their cars. Is it dispensable? At the same time, when replacing the gasoline filter, how should we distinguish the inlet and outlet of the gasoline filter? So today we will talk briefly about Auto Oil Filter.
Auto Oil Filter is mainly divided into built-in and external types. The built-in type is installed inside the gasoline tank and before the gasoline pump inlet, and is combined with the gasoline pump. The external type is installed under the chassis of the car, but the external type generally has a filter before the gasoline pump inlet, which can filter larger particulate impurities, which is essentially a secondary filtration.
Literally speaking, Auto Oil Filter is a component that filters gasoline. Some people say that the gasoline we add at the gas station looks clean, why do we need to filter it? What will happen if it is not filtered? What is the impact on the engine? Although gasoline looks clean, there are many dust particles, mechanical impurities, colloids, water, etc. that we cannot see with the naked eye. If these impurities enter the fuel injection system, they will seriously damage the injector and aggravate the wear of the cylinder, so the gasoline must be filtered before entering the engine. The main function of Auto Oil Filter is to filter mechanical impurities, colloids and water in gasoline, provide clean gasoline to the engine, and store a small amount of gasoline to avoid interruption of fuel supply when the car uses a large amount of oil in a short time. In addition, it can buffer gasoline pressure and stabilize the pressure of the fuel system.
As mentioned earlier, Auto Oil Filter is used to filter impurities in gasoline. When used for a long time, it will reach the clogging limit. If it is not replaced for a long time, the filter paper will be full of impurities, colloids, etc., which will lead to poor permeability. The gasoline cannot be supplied to the engine in sufficient quantity, and then the car will have problems such as weak acceleration and insufficient power, so regular maintenance and replacement are required. So how often is it appropriate to replace the gasoline filter? This is mainly related to the quality of the fuel. The higher the quality and purer the gasoline, the longer the gasoline filter can be used. The dust holding capacity of the gasoline filter is also a very important influencing factor. Obviously, the larger the dust holding capacity of the gasoline filter, the longer it can be used. Generally speaking, it is recommended to replace the external gasoline filter at about 30,000-40,000 kilometers and the internal gasoline filter at about 60,000-80,000 kilometers.
Of course, this is not an absolute periodic regulation and needs to fluctuate according to the actual situation. When the car accelerates slowly or suddenly accelerates, it can be suspected that the gasoline filter is clogged, and we should consider replacing the Auto Oil Filter.
