The cost of rubber parts for automobile fuel lines is about 10% of the cost of an automobile. Except for most of the tires, other rubber products are small pieces that are also installed in the engine, fuel tank and other important parts of the car to ensure proper functioning. Let’s look at what hoses are commonly used in automobiles:
Automobile Air Conditioning Hose
During hot summers and cold winters, trucks will inevitably turn on the air conditioner to make the interior. This is where the air conditioning hose comes into play. The inner rubber layer of an automotive air conditioning hose is made of EPDM rubber. It has high and low temperature resistance and air tightness. Whether it is cold air in summer or hot air in winter, it can meet our needs.
Cooling water hose for automobile
Cooling water hose is mainly used in the cooling system of automobile. The main function of the automobile cooling system is to emit part of the heat absorbed by the heated parts in time to ensure that a good temperature is maintained so that the engine and other parts can work normally, and because the current domestic working temperature is Cooling water pipes can reach 120 degrees Celsius. Therefore, the inner and outer layers of the cooling water hose are made of vulcanized vulcanized EPDM rubber.
Automobile oil return hose
Most EFI vehicles now have a fuel return line. When the fuel pump is supplied to the engine, the fuel pump will supply more fuel to keep the engine fully running. In order to lower the pressure of gasoline and reduce fuel consumption, gasoline will eventually flow. Returning to the fuel tank, this process is accomplished through the return line of the car. Although he is an insignificant part of the engine, it plays a very important role in the proper functioning of the engine.
Moisture in the pneumatic system can corrode the pipes and affect braking effectiveness. In severe cases, it can even lead to brake system failure. Also, be sure to check the operation of the pump and the wear of the pump belt. If problems are found, they should be replaced promptly.
