Due to refining and processing reasons, the finished fuel contains a certain amount of impurities, moisture and gums. The function of the fuel filter is to filter the impurities in the fuel of the car to make the fuel supplied to the engine for combustion more pure.
Fuel filter (fuel grid) has three types: diesel filter, gasoline filter and natural gas filter. At present, vehicle engines are basically internal combustion engines, mainly using gasoline and diesel fuel. Gasoline filters are more common in cars, and diesel filters are more common in large and medium-sized trucks.
Nowadays, the gasoline filter and diesel filter are widely used in the micro-porous paper filter, phenolic resin treatment, made into a folded cartridge, with good performance, filtration efficiency, simple structure, low cost, easy maintenance and other advantages.
The differences between the two are mainly divided into the following aspects:
1. the structure is roughly the same: there are exchangeable and rotary.
2. The requirements of working pressure and oil temperature resistance: diesel filter is much lower than oil filter.
3.the requirements of filtration efficiency: diesel filter is much higher than oil filter.
4. Different substances for selective filtration: Diesel filter mainly filters suspended solids and particulate matter; Gasoline filter is mainly used to filter the colloidal substances in the working oil and the debris caused by mechanical wear.
5. the filter aperture is different:Because the viscosity of diesel oil is small, the flow is good, so the filter aperture is small; Because the oil viscosity is large, so the aperture of the filter element is also large.
6. Different filtering methods: Diesel filter and oil-water separator are generally composed of two-stage filtration. The oil-water separator is used to filter the water in diesel oil. Gasoline filters generally have only one stage, between the gasoline tank and the gasoline pump or between the gasoline pump and the carburetor.
Fuel filter is a consumable material, in the process of vehicle use, need regular replacement and maintenance, otherwise it will not play a qualified protection role. Therefore, do not choose inferior fuel filter when replacing filter.
The filter element material used in inferior fuel filter is poor, not only the filter effect is poor, long time in the oil immersion, the filter element itself will have the filter layer off, blocking the oil, resulting in insufficient fuel pressure, the vehicle can not start. At the same time, it will also cause abnormal pressure of fuel system, which will directly lead to insufficient engine power or insufficient combustion, damage the three-way catalytic converter, oxygen sensor and other valuable components, resulting in huge economic losses.
GHL has always served consumers with high-quality products. All products adopt original filter materials, with higher filtration accuracy, and can provide clean fuel that meets the requirements, effectively protect the engine, and have a longer service life.
