What is the model number of all-season gear oil?

All-season gear oils are marked with a 'W' and can be selected based on the vehicle. Basic introduction to gear oil: 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. Gear oil primarily serves to lubricate gears and bearings, prevent wear and rust, and assist in heat dissipation for gears. Automotive gear oil is used in gear transmission mechanisms such as steering gear, 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. Basic properties of gear oil: Suitable viscosity and good viscosity-temperature characteristics; viscosity is the most fundamental property of gear oil. Higher viscosity results in a thicker lubricating oil film and relatively greater load-bearing capacity. Sufficient extreme pressure anti-wear properties; extreme pressure anti-wear is the most important and characteristic property of gear oil, essential for preventing wear, scuffing, and scoring on gear surfaces during operation. Good anti-emulsification properties; emulsification of gear oil upon contact with water can severely affect the formation of lubricating oil films, leading to scuffing and wear. Good oxidation stability and thermal stability; good thermal oxidation stability ensures the service life of the oil. Good anti-foaming properties; persistent foam can hinder the formation of oil films at gear meshing points, and trapped foam reduces the actual working oil volume, affecting heat dissipation. Good rust and corrosion prevention properties; corrosion and rust not only damage the geometric characteristics and lubrication state of gears but also further degrade the gear oil, creating a vicious cycle. Gear oil should also possess other properties, such as adhesiveness and shear stability. Currently, most medium and heavy-duty industrial gear oils in China use sulfur-phosphorus-based extreme pressure additives, which are comparable in quality to similar products abroad.

Can a repainted car still have a paint protection film applied?

Repainted cars can have paint protection films applied, but there are both advantages and disadvantages to applying an invisible paint protection film after a car has been repainted. Advantages: First, car owners must understand that repainted areas differ from the original factory paint in terms of aging speed, hardness, and other factors. Typically, color differences become noticeable after about a year (especially on white cars). The purpose of an invisible paint protection film is to prevent scratches, block external corrosion, and shield against UV radiation from the sun. This effectively compensates for the flaws in the repainted areas, eliminating concerns about color discrepancies. Disadvantages: Although the paint protection film safeguards the car's paint, it doesn't completely prevent all scratches. When the film suffers irreparable damage, it must be removed. However, because the adhesion of repainted areas may be poor (depending on the type of paint and the painting process), there is a chance that removing the film could also strip off the paint, ultimately damaging the car's finish.

Can a Rusted and Rotten Car Rocker Panel Be Repaired?

Car rocker panel damage can be repaired, but the results may not be ideal. Here is relevant information about car rocker panels: 1. Location: The rocker panel is situated at the door area of the vehicle and requires repair when damaged. 2. Material: Rocker panels are typically made of either plastic or steel. Currently, steel plates are the most commonly used material in the market due to their affordability. Another advantage is that steel plates are extremely durable, providing effective protection and offering a long service life. During normal driving, tires can easily kick up sand and gravel. With steel materials, these stones won't cause damage. Even occasional undercarriage scraping usually doesn't result in significant harm, and only severe cases might lead to minor deformation.

What is the optimal rear toe-in adjustment in millimeters?

In general, the optimal rear toe-in adjustment is approximately 5 millimeters. Below is relevant information about toe-in: 1. Definition: Due to wheel camber, the left and right wheels often generate opposing camber thrust forces corresponding to the camber angle, which increases tire wear. To prevent this, it's necessary to eliminate this camber thrust. The solution is to install the wheels such that the center planes of the two front wheels are not parallel, with the distance between the front edges being less than that between the rear edges. The difference between these distances is referred to as front wheel toe-in. 2. Function: Front wheel toe-in not only eliminates camber thrust to ensure normal tire wear but also ensures that the steering can automatically return to center after turning. Incorrect toe-in can result in the steering wheel failing to return to center automatically, causing the vehicle to feel unstable at high speeds. Additionally, it can lead to abnormal tire wear, with excessive wear on either the outer or inner edges.

How many days does it take to check the violation information for running a red light?

Generally, if you check through the online vehicle violation query system, it takes 5 working days to get the results. If you go to the vehicle management office or traffic police station to inquire, you can get the results the next day. Methods to check for running a red light: You can check for running a red light through the "Traffic Management 12123" APP. After opening it, log in with your ID card, then find and click on the violation handling option. In the violation handling section, you can see the current status of your vehicle. If there is a violation, the specific details of the violation will be displayed. Visit the office halls of the traffic police departments in various districts and counties to inquire through touch query terminals. Log in to the external service websites of the public security traffic management bureaus of various cities: find the vehicle violation query section, enter the license plate number and vehicle engine number, and click to query.

How Many Seats Does a Bus Generally Have?

Buses can be single-decker or double-decker, with varying numbers of seats. Below are specific details about passenger car quota allocations: Conventional passenger car quotas: Individual and family quotas account for 95.5% of the annual conventional passenger car quota, totaling 38,200, with individuals and families participating in the same lottery pool; corporate quotas account for 4% of the annual quota, totaling 1,600; commercial passenger car quotas account for 0.5% of the annual quota, totaling 200. New energy passenger car quotas: Family quotas account for approximately 54.2% of the annual new energy passenger car quota, totaling 32,520; individual quotas account for approximately 36.1% of the annual quota, totaling 21,680; corporate quotas account for 5% of the annual quota, totaling 3,000; commercial passenger car quotas account for approximately 4.7% of the annual quota, totaling 2,800.

How Much Does Tesla's LFP Battery Range Decrease in Winter?

Tesla's LFP battery has a range of 468KM. Under low-temperature winter conditions, vehicles equipped with LFP batteries experience a 35% reduction in range. Additional information about LFP batteries is as follows: 1. Working Principle: It is a lithium-ion battery that uses lithium iron phosphate (LiFePO4) as the cathode material and carbon as the anode material. The nominal voltage of a single cell is 3.2V, with a charging cutoff voltage of 3.6V~3.65V. During charging, some lithium ions in the lithium iron phosphate are extracted and transferred through the electrolyte to the anode, embedding into the carbon material of the anode. Simultaneously, electrons are released from the cathode and travel through the external circuit to the anode, maintaining the balance of the chemical reaction. During discharge, lithium ions are extracted from the anode, travel through the electrolyte to the cathode, while the anode releases electrons that travel through the external circuit to the cathode, providing energy to the external circuit. 2. Advantages: LFP batteries offer high working voltage, high energy density, long cycle life, excellent safety performance, low self-discharge rate, and no memory effect.
