Expansion tank is a small tank used to protect closed (not open to atmospheric pressure) water heating systems and domestic hot water systems from overpressure. The tank is partially filled with air, and its compressibility cushions the shock caused by water hammer and absorbs excess water pressure caused by thermal expansion. -
In a high temperature working environment, the engine must be properly cooled to keep it working at a suitable temperature to meet the requirements of good engine performance, durability and exhaust emissions. The engine cooling system plays a key role here. Includes critical cooling fans, water tanks, thermostats, and more. -
Car radiators usually refer to engine radiators. The radiator consists of three parts: the water inlet chamber, the water outlet chamber, the main piece and the radiator core. The coolant acts in the radiator core, and the air passes through the radiator core. The hot coolant is cooled by dissipating heat to the air, and the cold air is warmed by receiving heat from the coolant, so the radiator is a heat exchanger. -
Intercoolers are usually found on turbocharged cars. Because the intercooler is actually a supporting part of the turbocharger, and its function is to improve the ventilation efficiency of the turbocharged engine. -
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. -
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 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. -
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 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. -
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 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. -
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. -
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. -
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. -
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. -
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.
