Car rearview mirrors may fail to retract automatically due to the owner manually folding them, which can disable the automatic retraction function, or it could be caused by a disconnected or dead battery. Below is relevant information about car rearview mirrors: 1. Working Principle: Rearview mirrors have a field of view issue, referring to the range that the mirror surface can reflect. The industry mentions three elements of the field of view: the distance between the driver's eyes and the rearview mirror; the size of the rearview mirror; and the radius of curvature of the rearview mirror. 2. Design Points: The aspects include the obtainable field of view (indirect vision), image distortion, image clarity, image size, and the position of the image in the rearview mirror, making it easy to adjust according to changes in the driver's viewpoint. 3. Classification: They can be divided into three main series: flat mirrors, spherical mirrors, and double-curvature mirrors. There is also another type called the prism mirror, which has a flat surface but a prism-shaped cross-section, commonly used as an anti-glare interior rearview mirror.

What is the difference between GL4 and GL5 gear oil?

The differences between GL4 and GL5 gear oil are as follows: 1. GL-5 grade gear oil contains more sulfur compared to GL-4 grade oil. 2. GL-4 grade is a medium-duty gear oil, suitable for differential gears, transmission gears, and steering gears. 3. GL-5 is a heavy-duty gear oil, suitable for differential gears and rear axle gears operating under extremely harsh conditions. Here is more information about gear oil: 1. Gear oil mainly refers to the lubricating oil used in transmissions and rear axles. It differs from engine oil in terms of usage conditions, composition, and performance. 2. Gear oil primarily functions to lubricate gears and bearings, prevent wear and rust, and assist in heat dissipation for gears. 3. Automotive gear oil is used in gear transmission mechanisms such as steering systems, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oil plays a crucial role in lubrication, anti-wear, cooling, heat dissipation, anti-corrosion, rust prevention, cleaning, and reducing gear surface impact and noise.

How many 26-inch suitcases can fit in the trunk?

Approximately three 26-inch suitcases can fit in the trunk. Below is relevant information about placing luggage in the trunk: 1. Number of suitcases that can be placed: A sedan can accommodate three 26-inch suitcases, leaving some small gaps for smaller items. A suitcase, also known as a travel case or pull-along case, is a box used to carry items when traveling. It is one type of luggage. Typically, suitcases are used to store clothes, personal care items, and souvenirs needed for a trip. 2. Weight limit for luggage: The brand of the car and the number of passengers can affect the trunk's weight capacity. Luggage weight = Total vehicle weight - Curb weight - Driver and passenger weight. Most 1.5L sedans can carry an additional 100 kg of luggage with four passengers. Under normal circumstances (with only the driver), the trunk can hold items not exceeding 200 kg. Carrying excessively heavy items for long periods will significantly increase fuel consumption, reduce vehicle stability, and accelerate tire wear.
