what’s the use?
The air cleaner: ensure clean air into the engine
Many of dust suspended in the air, the main ingredient is silica, a metal which is a more than hard material, mounting the air cleaner can reduce wear of the cylinder, the piston and piston rings and other parts. As it is not car mounted, 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: guaranteed clean fuel, prevent vapor lock
In the gasoline storage and filling process, inevitably mixed into the free water and some impurities, as these impurities with fuel the fuel supply system and an engine cylinder, the cylinder will accelerate wear. 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 filter
during engine use, dust, metal debris, clean mechanical carbon impurities will continue mixed with the oil, 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 accelerate the wear of moving parts, but could easily lead to an oil passage blocked. In order to ensure clean oil, engine equipped with the lubrication systemOil filter.

What time change?
The air cleaner
Most automobile engines is small in quality, low cost, easy to replace, high filtration efficiency paper element dry air filters, general cleaning once every travel 5000 km. Remove the filter cleaning should gently tap 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. Each driving 25,000 kilometers must replace the air filter.
The oil filter
Most car engine using spin-on oil filter, this filter is not washable disposable filter, replace the oil when when the oil filter must be replaced, otherwise it will affect the quality of lubricating oil. Change the oil and oil filter cycles are generally 5000 km.
fuel filter
are the most disposable non-washable type of engine fuel filter paper filter tops, imported filter replacement cycle is generally 10,000 km. Oil inlet filter has an arrow mark, do not hold against replacement.
