Weichai k2440 Air filter original spare parts

Detailed product information

Great key performance parameters

Low absorption resistance: the absorption of the high -performance Weichai air filter is only 2.0 kPa, which is better than 2.3 kPa in competing products. It can provide a large volume of air absorption and effectively improve power response.

High filtering efficiency: due to the initial filtration efficiency of up to 99.8%, which is higher than that of competing products (99.5%), it can carefully filter the air and extend the engine service life.

High dustiness: a two -layer composite gradient filter material with a dustiness of 2650 g is used, which is significantly higher than the dustiness of 2100 g in competing products using ordinary filter paper. This allows you to significantly reduce the frequency of soot purge, extend the service life of the air filter element and reduce the replacement frequency.

Excellent material: made of high -strength polyurethane, does not have the ability to exfoliate and not deform, which allows reducing the likelihood of breakdowns and adapt to severe operating conditions.

Rational design: the air filter consists of an air intake pipe, air filter cover, air filter and filter element, and all parts work in close interaction, ensuring the effect of filtration and the effectiveness of air circulation.

Installation method

Preparation: Make sure that the car has cooled to room temperature, prepare tools such as wrench and screwdrivers, and find the air intake pipe of the car, which is usually located in the front of the motor compartment and is connected to the engine air intake.

Disassemble the original air filter: remove the original air filter cover. Usually you need to unscrew two screws, and then carefully remove the original air filter. Be careful not to damage the sealing ring on the filter.

Clean the air filter housing: use a clean rag or compressed air to clean the inside of the air filter body from dust and garbage.

Install a new air filter: place a new air filter in the filter box in the right direction, make sure that the sealing ring is correctly installed on the filter, and the filter is tightly inserted into the box. Be careful, do not make efforts so as not to damage the filter.

Fasten the air filter housing: install the new air filter lid in place and tighten the screws with a wrench to ensure tightness.

Check the installation position and tightness: check if a new air filter is installed correctly and whether the connection to the intake pipe is sealed. Touch the surface of the new air filter to check if there is a leak. If there is a leak, check the installation position again and tighten the screws.

Common malfunctions

The clogging of the filter element: too much dust and solid particles in the air will lead to the fact that the filter element will accumulate more dust and dirt, increase the resistance of the inlet, lead to insufficient air supply, affect the effectiveness of combustion and lead to symptoms such as a difficult launch engine, weak acceleration, unstable idle stroke, increased fuel consumption, and can also become The reason for the appearance of black smoke from the exhaust pipe.

Damage to the filter element: during use, the filter element can be damaged due to external exposure, aging or quality problems, which will lead to non-filtered air entering the engine, accelerate wear of the internal components of the engine, reduce engine productivity or even damage.

Incorrect installation: if the air filter is installed incorrectly, for example, the filter is installed crookedly or the sealing ring is not installed in place, this will violate the circulation of air, which will lead to the lighting of the engine malfunction indicator, and can also lead to air leakage, which will reduce the engine power.

The problem with the air hose: the hose connecting the air filter can have problems such as detaching or cracking the inner layer, which can lead to the appearance of black smoke from the exhaust pipe after starting the engine and stopping the engine after launch.

Below are solutions to the common faults of the Weichai air filter:

The filter element is clogged

Clean the filter element: for some cleaned air filter elements, such as paper filtering elements, you can use compressed air to blow the inside of the filter element to blow dust and pollution, adhering to the surface of the filter element. The pressure of compressed air should not be too high and is usually controlled in the range of 0.2-0.3 MPa to avoid damage to the filter element. During cleaning, be sure to evenly blow out all parts of the filter element to guarantee the complete removal of dust.

Replace the filter element: if the filter element is very clogged and its performance is not restored after cleaning, or the filter element has reached the established service life, it should be replaced in a timely manner with a new one. When replacing the filter element, choose a filter element corresponding to the car model and the engine to ensure its filtering effect and air intake performance.

The filter element is damaged

Check the degree of damage: discovering damage to the filter element, first carefully check the place and degree of damage. If the damaged area is small, you can consider the possibility of its repair; If the damaged area is a large or damaged part is located in a critical position, the filtering element should be replaced immediately.

Repair of the filter element: to eliminate minor damage, you can use special materials for the repair of the filter element. Apply repair material to the damaged area, making sure that it is applied evenly, and then wait until it dries and hardens. After the repair, check the filter element to make sure that the damage is reliably eliminated and will not affect the effectiveness of filtering the filter element.

Replace the filter element: if the filter element is seriously damaged and its performance cannot be restored by repair, it should be replaced in a timely manner with a new one. When installing a new filter, pay attention to its correct installation and provide a good seal between the filter element and the air filter housing to prevent non -finished air entering the engine.

Incorrect installation

Reinstall the filter element: if you find that the filter element is installed incorrectly, immediately stop using the vehicle and reinstall the filter element. When installing the filter element, carefully read the operating manual for the car and follow the correct instructions for installing it. Make sure that the filter element is in place, the seal between the filter element and the air filter housing is not damaged, and the input and output holes for the air of the filter element are correctly connected to the air filter tube.

Check the state of the seal: after installation, check the state of the seal between the filter element and the air filter case. You can touch the edge with your hand and connect the filter element to check it for leaks. If air leakage is detected, adjust the installation position of the filter element or replace the sealing ring to ensure proper tightness.

Air hose problem

Check the hose: In case of problems such as detaching or cracking the inner layer of the air hose, carefully check each part of the hose to determine the specific place and degree of malfunction. If the inner layer of the hose exfoliates, this can lead to a deterioration in air circulation and affect the engine air intake; If the hose breaks, this will lead to a leakage of air and a decrease in engine power.

Replace or replace the hose: with minor tears of the hose, you can use a special tool for repairing a hose or sticky tape. Wrap the place of rupture with a patch or ribbon to ensure reliable sealing. If the inner layer of the hose is greatly exfoliated or cracked and its operational characteristics cannot be restored by repair, the hose should be replaced in a timely manner. When replacing the hose, choose a hose with the same characteristics and material as the original hose to guarantee its quality and performance.

Fasten the hose: After installing a new hose, make sure that it is securely fixed to avoid weakening or displacement during the movement of the car. You can use clamps or other fixing devices to fix the hose in the correct position and provide a sealed connection between the hose, air filter and the engine air intake.
