Lubricating oil and grease differ in the following aspects: 1. Adhesion properties: When the friction part is in a static state, grease can maintain its original shape without automatically losing due to gravity, nor will it slide off vertical surfaces or leak through gaps. This characteristic makes it particularly suitable for friction parts that are frequently started and stopped, parts where replenishing grease is difficult, and open or poorly sealed areas. 2. Temperature range: Grease has a wider working temperature range compared to lubricating oil. 3. Pressure resistance: Grease has much stronger adsorption capability on metal surfaces than lubricating oil and can form a more robust oil film, capable of withstanding higher working loads. This is due to the large amount of polar substances contained in grease.

How Early Can Vehicle Annual Inspection Be Conducted?

Vehicle annual inspection can be conducted up to 3 months in advance. For example, if the inspection validity period of a vehicle expires in September this year, then the annual inspection can be performed from July 1st to September 30th of the same year. There are several ways to check the annual inspection time. The most straightforward method is to refer to the vehicle's driving license and compulsory traffic insurance electronic policy, which contain the registration date of the vehicle. The registration month indicates the month when the annual inspection is due. Additionally, you can directly observe the annual inspection sticker, which clearly prints the validity period of the inspection. Points to note for annual inspection: Vehicles that fail the annual inspection must be repaired within a specified time limit. If they still fail after the deadline, the vehicle management office will confiscate their license plates and prohibit them from continuing to operate. Vehicles that do not undergo the annual inspection without reason or fail the inspection are not allowed to drive on roads or transfer ownership. Vehicles that meet the scrapping conditions or have exceeded the prescribed service life will not be inspected, and their license plates will be revoked, records deleted, and the vehicles will be scrapped.

How to Solve the Airbag Light On Issue?

Solution for the airbag light being on: Take the vehicle to a 4S dealership for computer diagnosis and troubleshooting. The airbag light being on indicates a fault in the airbag system, which does not affect normal driving. However, in the event of a collision, the airbag may fail to deploy properly. The airbag system, also known as the Supplemental Restraint System (SRS), mainly consists of two parts: the seat belt pretensioner mechanism and the airbag itself. Key components include collision sensors, the airbag indicator light, the airbag control module, and the airbag. The connectors that link these crucial components are equally important. Some connectors even feature a dual-locking mechanism to ensure more reliable connections. Additionally, to distinguish them from other connectors, all airbag system connectors are yellow.
