In the power system of modern vehicles, various belts play a vital role. Among them, the generator belt, air conditioning belt and timing belt are one of the core components to maintain the efficient operation of the engine and the smooth operation of the equipment in the car. These seemingly inconspicuous small parts have a direct impact on the performance of the vehicle and the comfort of the driver.

Let's start with their respective roles! First of all, let's look at the generator belt, which is mainly responsible for driving the power generation device to generate power to supply the battery and other electronic components. Secondly, there is a special transmission part on the air conditioner compressor-the so-called "air conditioner belt". Only with it can we ensure the normal effectiveness of the cooling and heating function. Finally, we cannot ignore the key figure who silently guards the heartbeat rhythm of the engine-the timing belt, once there is a problem, it will lead to serious mechanical failure and even destroy the whole machine ~

However, the market is full of similar products of various brands. How to choose the one that suits your car? The answer lies in a deep understanding of the differences between different materials. At present, there are two categories of traditional natural rubber products and emerging synthetic fiber composite profiles to choose from:

• The former is soft and easy to bend and easy to install, but it is easy to age and deform under high temperature and high pressure environment to shorten the life span;

• The latter is famous for its super wear resistance and stretch resistance, even in the face of bad weather conditions can maintain stable physical properties without deterioration or damage.

in addition to considering the above factors, it is also necessary to make more accurate and detailed judgment decisions in combination with specific vehicle type information. dear friends ~ generally speaking, manufacturers will attach a detailed technical parameter table as a reference basis, please be sure to carefully check all the data indicators of your car before placing an order for shopping so as not to cause unnecessary trouble by buying the wrong goods. another point worth noting is not to simply pursue the temptation of low-price promotion and ignore the fundamental requirements of quality and adaptability!

of course, even the best things need proper care to stay with them for a long time, don't they? The daily maintenance work mainly includes the following aspects:
① Regularly check whether the tightness setting is appropriate and reasonable, too loose will lead to skidding, thus reducing work efficiency and increasing energy consumption and loss;
② timely remove surface oil dust and impurity particles deposits to prevent blocking of heat dissipation pore channels and affecting ventilation and cooling effect;
③ Reasonable planning of replacement cycle frequency arrangement timely replacement of old damaged parts to avoid sudden accidents and economic losses.

in response to the questions and puzzles raised by many friends, we have specially sorted out some typical representative examples and given professional authoritative answers as follows:
Q1:"my car has been driving for several years, and now I feel that the idling jitter is severe. is it related to these three guys?"
A1:"there is a great possibility that there is a connection. it is suggested to go to a regular repair shop as soon as possible for a comprehensive inspection to confirm the specific situation and deal with and repair the root cause of the problem in time. "
Q2:" I heard that some places recommend rinse with water to clean up the dirty place outside. Is this feasible? "
A2:" Absolutely not! Because moisture intrusion into the internal structure will cause rust and corrosion of metal parts and accelerate the wear and scrap speed of parts, the correct way should be to use a clean dry cloth to gently wipe the appearance."
