It should be noted that the timing belt is not the only rubber material. Some models use a metal chain for the timing belt, which is the timing chain in our mouth. The replacement cycle between them must be different. Generally speaking, the replacement cycle of the timing chain is longer than that of the timing belt, and the replacement cost will be higher.

Timing chain

Even if they are all timing belts, the replacement cycle will vary from model to model. Usually the car timing belt replacement cycle is around 60,000 kilometers, and the general timing chain is free of replacement, and a few need to be replaced is also more than 100,000 kilometers. However, the specific time is subject to the calibration cycle of each model. The car owners can check it through their car maintenance manual.

Timing belt

Of course, the specific replacement cycle not only needs to refer to the replacement requirements of the vehicle model, but also needs to be adjusted according to your driving habits and maintenance habits. In addition, when the timing belt needs to be replaced, the related accessories will also be replaced together. Unless serious quality problems occur, the accessories will need to be replaced together when the timing belt is replaced.

When changing the engine belt, be sure to align the timing before removing the timing belt. Only when the timing is correct can the tensioner be removed. Only then can the belt be removed. Try not to get the mark wrong when installing the belt. After installing the belt, use a wrench to turn the crankshaft twice, and then look at the mark. If the mark is correct, install other things on the top. Now most cars are easy to top the valve, so the timing mark must be correct. Replace on time according to the requirements of the user manual.

If you feel that you can't solve it, you can go directly to the repair shop to get the , and you must choose a regular repair shop. Because the small repair shop does not have any quality assurance, it may also lead to consumers being deceived.

1. Four Components of Air Conditioning and Refrigeration System

The four components of air conditioning refrigeration system are evaporator, condenser, compressor and throttle valve. Air conditioning can be refrigerated or heated. Condenser is one of the four major components of air conditioning refrigeration system. Condenser can take away the heat absorbed by evaporator.

2. The working principle of Honda ac condenser replacement:

The working principle of the condenser is mainly based on the second law of thermodynamics. The working principle of the condenser is analyzed and explained in detail through the following schematic diagram.

Detailed analysis of the working principle of condenser: Condenser air conditioning system components can transfer heat from the tube to the air near the tube in a quick way. Most of the condensers on automobiles are installed in front of the water tank. It is a device for converting gases or vapors into liquids.

For some applications, the gas must pass through a long tube (usually coiled into a solenoid) to dissipate heat to the surrounding air. Thermal conductive metals such as copper are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks are often attached to the pipeline to accelerate heat dissipation. The radiator is a flat plate made of good thermal conductive metal. This type of condenser usually uses a fan to force air through the radiator and take the tropics away. Generally, the refrigeration principle of refrigerators is that the compressor compresses the vapor with lower pressure into vapor with higher pressure, which reduces the volume of vapor and increases the pressure. The compressor sucks the working substance vapor with lower pressure from the evaporator and sends it to the condenser after the pressure rises. The liquid with higher pressure condenses in the condenser and is throttled by the throttle valve.

3. The main uses of Honda ac condenser replacement:

1) As one of the four major components of refrigeration system, the function of condenser is to take away the heat and cold absorbed by evaporator.

2) Many condensers are used in power plants to condense the steam discharged from turbines.

3) Condensers are used in refrigeration plants to condense refrigerating vapors such as ammonia and fr-eon.

4) Condensers are used to condense hydrocarbons and other chemical vapors in petrochemical industry. In the distillation process, the device that converts vapor into liquid is called condenser. All condensers operate by taking away heat from gases or vapors.

Through further understanding of the condenser, it will be helpful for us to maintain the condenser in the future. As the main material of condenser is copper and steel carbon, corrosion leakage often occurs between welds, which will cause environmental pollution. Therefore, in view of the anti-corrosion problem of condenser, polymer composites can be used and regular cleaning should be paid attention to.

According to the basic principle of "Where there is demand, where is production", Honda actively promotes the modernization system and develops, produces and sells products adapted to the needs of customers in different regions (including 92 production bases around the world, including China, and 13 research and development institutions at home and abroad).

As an international enterprise to promote localization, it not only means to integrate into local customs and culture, but also means to share the same "ideal" and "idea" with people all over the world, to share all business resources, and to carry out various activities at the same time.

The Honda, which started from the manufacture of bicycle auxiliary engines, has been developing not only in the field of modern vehicles such as automobiles and motorcycles, but also in the field of general products, which involves various industries and entertainment industries.
