What is the standard for belt tension?

1 Answers

Belt tension can be roughly judged by hand pressing. The inspection method is very simple: use your thumb to forcefully press the belt between two pulleys with a pressure of about 10kg. If the belt depression is around 15mm, the belt tension is considered just right. Additional information is as follows: 1. Due to the elasticity of the belt, it can cushion impact, reduce vibration, and ensure smooth transmission, but it cannot maintain a strict transmission ratio (the ratio of the driving pulley's revolutions per minute to the driven pulley's revolutions per minute). When the transmission encounters obstacles or overload, the belt will slip on the pulley, thus preventing damage to the machinery. 2. Belt transmission is simple, cost-effective, easy to maintain, and convenient to replace. However, due to belt slippage on the pulley, the mechanical efficiency of belt transmission is low, and the belt itself has poor durability. Over time, it will gradually stretch, so adjustments should be made as needed.

Is It Necessary to Clean the Intake System?

It is necessary to clean the intake system. Since there is currently no complete method to prevent carbon deposits, if not cleaned regularly, carbon deposits will accumulate endlessly. Once carbon deposits build up in the intake system, it can cause issues such as engine shaking and reduced power in mild cases, and in severe cases, it may even lead to engine cylinder scoring or seizure. There are generally two cleaning methods for the intake tract: drip cleaning and disassembly cleaning. The intake system consists of components such as the air filter, air flow meter, intake pressure sensor, throttle body, auxiliary air valve, idle control valve, resonance chamber, power chamber, and intake manifold.

How to Use a Manual Anti-Glare Rearview Mirror?

Manual anti-glare rearview mirror usage: When the vehicle is exposed to strong light from behind, the manual anti-glare rearview mirror requires the driver to manually activate the anti-glare function to block the intense light from affecting the driver's vision. When not needed, the driver can manually deactivate the anti-glare function to clearly observe the traffic conditions behind. The anti-glare rearview mirror consists of a special mirror, two photodiodes, and an electronic controller. The two photodiodes are positioned on the front and back of the rearview mirror, respectively receiving light from the front and rear of the vehicle. When the headlights of a following vehicle shine on the rearview mirror, the light from behind becomes stronger than that from the front. This contrast is detected by the two photodiodes, which send an electrical signal to the electronic controller, applying voltage to the conductive layer of the mirror. This causes the electrochromic layer of the mirror to darken, ensuring that even the strongest light reflected on the mirror does not reach the driver's eyes.
