Classification of air filters

The filter element of the air cleaner is divided into two types: dry filter element and wet filter element. The dry filter element material is filter paper or non-woven fabric. In order to increase the air passage area, most of the filter elements are processed with many small folds. When the filter element is slightly fouled, it can be blown with compressed air. When the filter element is seriously fouled, it should be replaced with a new one in time.

The wet filter element is made of sponge-like polyurethane material. When installing it, add some oil and knead it by hand to absorb foreign matter in the air. If the filter element is stained, it can be cleaned with cleaning oil, and the filter element should be replaced if it is overly stained.

If the filter element is severely blocked, the air intake resistance will increase and the engine power will decrease. At the same time, due to the increase in air resistance, the amount of gasoline sucked in will also increase, resulting in an excessive mixing ratio, which will deteriorate the engine’s running state, increase fuel consumption, and easily produce carbon deposits. Usually, you should develop to check the air filter filter frequently

Core habits.

Impurities in the oil filter

Although the oil filter is isolated from the outside world, it is difficult for impurities in the surrounding environment to enter the engine, but there are still impurities in the oil. Impurities are divided into two major categories:-category is metal particles worn down by engine parts during operation and dust and sand that enters from the fuel filler when replenishing engine oil; the other-category is organic matter, which is black muddy.

It is a substance produced by chemical changes in engine oil at high temperature during engine operation. They deteriorate the performance of the engine oil, weaken the lubrication, and stick to moving parts, increasing resistance.

The former type of metal particles will accelerate the wear of the crankshaft, camshaft and other shafts and bearings in the engine, as well as the lower part of the cylinder and the piston ring. As a result, the gap between the parts will increase, the oil demand will increase, the oil pressure will drop, and the cylinder liner and piston ring The gap between the engine oil and the piston ring is large, causing the oil to burn, increasing the oil volume and

Formation of carbon deposits.

At the same time, the fuel drains to the oil pan, which makes the engine oil thinner and loses its effectiveness. These are extremely unfavorable to the performance of the machine, causing the engine to emit black smoke and severely drop its power, forcing an overhaul in advance (the function of the oil filter is equivalent to the human kidney).
