“three filter” refers to an air filter, fuel filter and oil filter. .
What is the use of three filter 1
The air cleaner: ensure clean air entering the engine lot of dust floating in the air, the main ingredient is silica, which is a ratio of the metal harder material, mounting the air cleaner can reduce wear of cylinder, piston and piston rings and other parts.
The car does not install it, the cylinder wear increased 7-fold, 3-fold increase in the wear of the piston, piston ring wear will increase 8 times.
Thus in modern automotive engine carburetor (or EFI engine intake control device) equipped with an air cleaner unit off.
Fuel Filter: to ensure a clean fuel, gasoline prevent vapor lock during filling and storage, will be inevitably mixed with free water and some impurities, as these impurities into the fuel supply system and the engine cylinders , the cylinder will accelerate wear and tear.
before entering the petrol fuel pump, filtration must be carried out to ensure the normal operation of the gasoline supply system.
Oil Filter: oil filter, to ensure the normal operation of the engine, the three most important engine filter during use, the dust,Metal debris, carbon Qing mechanical impurities mixed in the oil will continue, while the exhaust gas and combustion air oxidation of the oil, the oil also will gradually produce gum, gum mechanically mixed with the impurities also the formation of sludge, it will not only accelerated wear of moving parts, and could easily lead to oil plug.
To ensure clean oil, lubricating oil filter equipped with the engine system.
2. When three filters transducer
Most automobile engines use air cleaner is small in quality, low cost, easy to replace, high filtration efficiency of the dry filter paper air filter, general cleaning once every travel 5000 km.
taken when cleaning the filter gently tapping the end face, using compressed air to blow out from the inside, in order to remove dust on the core, do not wash with water or gasoline.
must be replaced with each of the 25,000 kilometers of the air cleaner.
Most car engine oil filter using a spin-on oil filter, this filter is not washable disposable filter, replacement of oil when the oil filter must be replaced, otherwise it will affect the quality of lubricating oil.
Replace the oil and oil filter cycle, is generally 5,000 km.
Most of the engine fuel filter tops are disposable paper filter can not be taken off of the fuel filter, imported filter replacement cycle is generally 10,000 km.
oil inlet filter has an arrow mark, do not hold against replacement.
