Oil filter

It filters out the mechanical impurities and gum during engine operation, protect lubricating oil clean. Fuel filter

It filters out engine fuel system’s harmful particles and water, to protect the pump nozzle, cylinder liner, piston rings, and reduce wear, avoid blocking, which is divided into gasoline and diesel filter device.

B. In addition to filtering the mechanical impurities in diesel fuel filter, there is an important feature is the treatment. To keep the relevant parts cleaning: air filter can maintain below parts clean. Oil filter use the filter material of filters paper, felt, metal, non-woven cloth.

Automotive filter applications:

A.

Second, the filter classification and working principle

Engine has three kinds of filters, air filter, oil filter, fuel filter, commonly known as the "three filters. The role of oil filter is to filter out harmful impurities from the sump to clean the oil supply crankshaft, connecting rod, camshaft, turbocharger, piston rings and other sports deputy, have the lubrication, cooling and cleaning effect, thus extending the life of these parts.

Diesel fuel filter and oil filter structure roughly the same, there are replaceable and the spin two types. Air filter can filter out the pollen of outside air’s dust, harmful substances, bacteria and toxic gases. Auto Filter is designed to protect personnel ride.

Divided into four categories

1." They are responsible for the engine intake system, lubrication system and media filter of combustion systems. Oil-water separator

According to the density difference between water and fuel, it’s a separator of using principles of gravity settling to remove impurities and moisture

Third, the structure and function of the air filter

Air filter is in the engine intake system, it is composed of one or several cleaning air components.

C. There are two types of air filter, namely dry and wet. The main role of the air filter is to filter the harmful aluminum tube impurities in air entering the cylinder, in order to reduce the cylinder, piston, piston rings, valve and valve seat wear and tear early. The diesel filter mostly use the filter paper, there is also felt or polymeric materials.
First, the concept of auto filter

Automotive filters’ filtrations have high performance, long life, durable vibration, durability, and will not allow dust to leak, water resistance, do not block the entry of air, light and are easy handling. Upstream of oil filter is oil pump; downstream is the engine parts that need lubrication.

2. Carbon Auto Filter: its difference to air conditioning filter is that it has more a layer of activated carbon filter layer, have further absorption of toxic gases.

Fifth, the fuel filter structure and function

Fuel filters includes diesel filter, oil filter and gas filter.
4.

3. Oil filter according to the structure can be divided into replaceable, spin, centrifugal; according to the layout of the system can be divided into full-flow type, shunt type.

Fourth, the oil filter structure and function

Oil filter is located in the engine lubrication system. But its work pressure and oil temperature requirements are much lower than the oil filter, and its filtration efficiency requirements are much higher than the oil filter. Auto Filter recommended replacement cycle is 10,000 kilometers. Air filter

It is to remove particulate impurities in the air device.


. The role of fuel filter is to filter out the harmful particles and water in the engine fuel gas system, to protect the pump nozzle, cylinder liner, piston rings reducing wear and avoid congestion
