The plastic bumper is composed of three parts: the outer plate, the buffer material and the beam. The outer plate and buffer material are made of plastic, and the beam is stamped with a cold-rolled sheet with a thickness of about 1.5 mm to form a U-shaped groove; the outer plate and buffer material are attached to the beam, and the beam and the frame longitudinal beam are screwed together, which can be used at any time. Remove it. The plastic used in this plastic bumper is generally made of polyester and polypropylene. -
In addition to being beautiful, the biggest role of the front bumper grille is to intake air and reduce air resistance. The greater the impact of the front grille on the resistance of the engine compartment, the resistance of the engine compartment accounts for about 10% of the total resistance, and the active closing of the grille is conducive to reducing the resistance in the engine compartment. In addition, the front bumper grille also plays a role in cooling. The front grille is the passage between the outside world and the engine compartment, through which the air enters the engine compartment, takes away the heat of the radiator, and cools it down. -
The cylinder head belongs to the valve mechanism in the internal combustion engine, and is mainly used to close the upper part of the cylinder to form the combustion chamber. In addition, it also serves as the support of the camshaft and the rocker shaft as well as the intake and exhaust pipes, mainly to suck the air into the cylinder, the spark plug ignites the combustible mixture, drives the piston to do work, and the exhaust gas is discharged from the exhaust pipe. -
Piston rings are metal rings that are embedded in the grooves of the piston. There are two types of piston rings: compression rings and oil rings. The compression ring is used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape excess oil from the cylinder. -
The function of the oil filter is to filter out the sundries, gums and moisture in the oil, and deliver clean oil to each lubricating part. -
A high-quality air conditioner filter can absorb powder tip particles, relieve respiratory pain, reduce irritation to allergy sufferers, make driving more comfortable, and protect the air conditioning cooling system. Please note that there are two types of air-conditioning filter elements, one without activated carbon and the other with activated carbon (consult before purchasing). The air-conditioning filter element containing activated carbon not only has the above functions, but also absorbs a lot of odors, etc. effect. The air-conditioning filter element is generally replaced every 10,000 kilometers. -
1. The air filter is the core component of the filter. It is made of special materials and is a wearing part, which requires special maintenance and maintenance; 2. When the air filter has been working for a long time, the filter element has intercepted certain impurities, which will lead to an increase in pressure and a decrease in flow. At this time, it needs to be cleaned in time; 3. When cleaning, be careful not to deform or damage the filter element. -
In the braking system of a car, the brake pad is the most critical safety part, and the brake pad plays a decisive role in the quality of all braking effects, so it is said that a good brake pad is the protector of people and cars. -
Gasoline filters and diesel filters are generally made of microporous paper filter elements, which are treated with phenolic resin and made into a folded cylinder type, which has the advantages of good passing performance, high filtration efficiency, simple structure, low cost, and easy maintenance. -
The replacement cycle of wiper blades is generally about a year, mainly depending on the frequency of use, and remember to clean the wiper blades with a towel after each rain, which not only increases the service life but also protects the glass. -
The brake disc is the friction couple of the disc brake. In addition to the strength and rigidity required as a component, it should also have a friction coefficient as high and stable as possible, as well as appropriate wear resistance, heat resistance and heat dissipation. and heat capacity, etc. . The brake disc needs to be replaced once every 70,000 kilometers. -
The stabilizer bar, also known as the anti-roll bar and the balance bar, is an auxiliary elastic element in the automobile suspension. The function of the anti-roll bar is to prevent the body from leaning excessively when cornering and to improve the driving stability of the car on uneven roads. -
Symptoms of a broken tie rod end mainly include the following conditions. First, if the tie rod end of the front wheel of the car is broken, the following symptoms will appear: the road section is bumpy, thump, thump; the car is unstable, swaying left and right; braking deviation; direction failure. The second is that the tie rod end is too wide, and it is easy to break when subjected to impact load. Repair as soon as possible to avoid danger. -
The fender is the outer panel of the body that covers the wheel, just like a bicycle shell, it has the functions of protecting the tire and mud, because the shape and position of the part of the body are named after the bird's wing. -
The main function of the oil pan 1009100-EG01 is to store oil (lubricating oil) and close the crankcase. The oil pan bears little force and is generally stamped from a thin steel plate. Its shape is determined by the general arrangement of the engine and the capacity of the oil. -
The timing belt is an important part of the engine's air distribution system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. The use of belts rather than gears for transmission is because belts are less noisy, less variable and easier to compensate for. Obviously, the life of the belt must be shorter than that of the metal gear, so the belt should be replaced regularly.
