Air filter replacement
Replacement cycle It is generally recommended that customers change every 15,000 km. Vehicles that often work in harsh environments should be replaced no more than 10,000 kilometers (desert, construction site, etc.).we are oil filter wholesale and best oil filter china,you can know it.
The service life of the air filter is 30,000 kilometers for cars and 80,000 kilometers for commercial vehicles. Filtration requirements for filters High filtration accuracy: Filter out all larger particles (>1 - 2 um).
High filtration efficiency: Reduce the amount of particles passing through the filter. Prevent early wear on the engine. Prevent damage to the air flow meter! Low differential pressure ensures optimum engine air-fuel ratio. Reduce
Large filtration area, high ash content and long service life. Reduce operating expenses. The installation space is small and compact. The wetness is high, preventing the filter element from sucking and causing the filter element to
be broken down. Flame retardant. The sealing performance is reliable. Good value for money.
Metal-free structure, environmentally friendly, reusable, and conducive to storage. The first step of the replacement step is to open the bonnet and confirm the position of the air filter. The air filter is usually located on the left
side of the engine compartment, that is, above the left front wheel. You can see a square black plastic box, and the filter element is installed. inside.
We simply lift the two metal clips up and lift the entire air filter cover. There are also some models that use screws to fix the air filter. In this case, you need to select a suitable screwdriver to unscrew the screws on the air
Remove the air filter. In the second step, remove the air filter to check if there is more dust. You can gently pat the filter end face, or use compressed air to clean the dust on the filter from the inside out. Do not rinse with tap
water. If you check that the air filter has been severely clogged, you will need to replace it with a new one (we can go to the 4S shop or Auto Parts City to buy the same model).
In the third step, after the air filter is processed, the air filter box needs to be thoroughly cleaned. Generally, a large amount of dust is accumulated under the air filter, and the dust is the culprit causing the engine power to
drop. The position of the filter, the air filter is generally located on the left side of the engine compartment, that is, above the left front wheel, you can see a square plastic black box, the filter is installed inside.
We simply lift the two metal clips up and lift the entire air filter cover. There are also some models that use screws to fix the air filter. In this case, you need to select a suitable screwdriver to unscrew the screw on the air
filter box and take out the air filter.
What is the use of oil filter?
Oil filters are available in full flow and split flow. The full-flow filter is connected in series between the oil pump and the main oil passage, so that all the oil entering the main oil passage can be filtered. The split type cleaner is connected in parallel with the main oil passage to filter only part of the lubricating oil sent by the oil pump.
During the working process of the engine, metal grinding debris, dust, oxidized carbon deposits and colloidal deposits at high temperatures, water, etc. are constantly mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and gels, to keep the lubricant clean and to extend its service life. The oil filter should have strong filtration capacity, low flow resistance and long service life.
A general lubrication system is equipped with filters of several different filtration capacities - a filter, a strainer and a fine filter, which are respectively connected in parallel or in series in the main oil gallery. (The full-flow filter is connected in series with the main oil passage. When the engine is working, the lubricating oil is completely filtered by the filter; the shunt filter is connected in parallel with it).
The strainer is connected in series in the main oil passage, which is a full flow type; the fine filter is connected in parallel in the main oil passage, which is a split flow type. Modern car engines generally only have a filter and a full-flow oil filter. The coarse filter filters out impurities having a particle diameter of 0.05 mm or more, and the fine filter filters out fine impurities having a particle diameter of 0.001 mm or more.
Technical characteristics of the oil filter: ● Filter paper: The oil filter requires higher filter paper than the air filter, mainly because the temperature of the oil varies from 0 to 300 degrees. Under severe temperature changes, the oil The concentration also changes accordingly, which affects the filtration flow of the oil. The filter paper of a high-quality oil filter should be able to filter impurities under severe temperature changes while ensuring sufficient flow.
●Rubber seal: The filter seal of high-quality oil is made of special rubber to ensure 100% oil leakage. ● Reflow suppression valve: only available in high quality oil filters. When the engine is turned off, it prevents the oil filter from drying out; when the engine is re-ignited, it immediately generates pressure and supplies oil to the engine.
(also known as check valve) ● Relief valve: only available in high quality oil filters. When the external temperature drops to a certain value or when the oil filter exceeds the normal service life, the relief valve will open under special pressure, allowing unfiltered oil to flow directly into the engine.
Despite this, the impurities in the oil will enter the engine together, but the damage is much smaller than the damage caused by the lack of oil in the engine. The relief valve is therefore the key to protecting the engine in an emergency.
