Under what circumstances does the automobile air filter need to be replaced?
Mechanical filters, air filters and air-conditioning filters may be familiar to everyone, but most of them ignore steam filters, gas filters and ordinary gasoline filters. They are one kind of fuel filters, and they are important components for automobiles to filter fuel impurities, provide clean fuel for engines and protect engines and fuel supply systems.
The replacement cycle of steam filter is relatively long, generally 30 thousand to 50 thousand kilometers, depending on the maintenance manual and actual use, as well as the quality of gasoline used at ordinary times. If the fuel impurity content is high, the probability of gasoline filter clogging will increase obviously, and the replacement cycle will be shortened accordingly.
In addition, it should be noted that when this phenomenon occurs in the car, other reasons should be ruled out. If the gasoline filter becomes dirty or blocked, it should be replaced. The internal combustion engine of a fuel truck needs both air and fuel. The essence of combustion is that oxygen in the air reacts with fuel.
Therefore, the air intake is very important, which determines whether the air intake is sufficient, whether the core air volume is normal, and whether the air filter is blocked. The air filter is basically a paper filter element with air permeability, but if the air filter is used for a long time, it will accumulate dust and dirt on the filter paper. If the air quality is too poor or the air humidity is too high, there will be "mud" on the air filter.
Similarly, it will also affect the intake volume. The cleanliness of air filter element (also called style, called air filter) directly affects fuel consumption. Air filter blockage will reduce the air flow into the engine intake, resulting in incomplete fuel combustion, and the engine can not even start the car, thus increasing fuel consumption.
If the filter element of air filter is not maintained or replaced for a long time, it will be full of dust, which will lead to the failure of the filter element. Foreign dust particles may be sucked into the cylinder, which will accelerate the wear of the piston and cylinder wall, seriously cause "cylinder explosion" and form coke-like carbon deposits on the air intake and throttle.
The function of air filter is to filter impurities in the air, such as leaves, dust, sand, flying insects and so on. Without the air filter, these things will enter the engine with the air intake of the engine, resulting in serious wear of the cylinder wall, which is often said.
If the cylinder is pulled, the fault phenomenon is that the fuel consumption increases, the acceleration is weak, the power is greatly weakened, some have not been changed, and black smoke will be emitted. This solution can only be repaired, and the maintenance cost is quite high. Some car owners will report that the air filter is dirty, will it blow?
It depends on the specific situation. Generally, when the air filter is not too dirty, we can blow it with an air gun, but we should pay attention to blowing it from the inside out. If the air filter is dirty, it is moldy and discolored. Direct replacement is recommended. Usually, if the air filter element is flooded, it means that the engine is flooded and may wade in summer.
If this happens, it is recommended that the owner turn off the engine first to avoid water in the engine cylinder. This is normal practice. We have to push the cart, open the air cleaner shell, clean the water, and then find a regular repair shop to clean it briefly. Finally, it is recommended to replace the air filter with water.
The maintenance and replacement of the air filter is very simple, and we can do it ourselves. The shell of the traditional air cleaner is fixed in place with a steel wire clip, and the shell can be opened and the filter element can be taken out by pulling hard. When blowing the air filter, the compressed air pressure should not be too high, only two or three pressures can be used, and it should be blown from back to front, not back.
Otherwise, its filtration performance will be reduced; In addition, the air filter must be replaced if it is blown no more than three times, otherwise the filtering effect will be poor. For car owners, the replacement cycle of automobile air filters should also be determined according to the use environment. For example, if the car often runs on dusty roads, it is best to replace it every 65,438+00,000 kilometers. If the car is used in a clean place, it can be replaced every 20 thousand kilometers.
