Oil shear value refers to the oil film strength of engine oil under high shear conditions at 150 degrees Celsius. The higher the value, the greater the strength. The following are the functions and requirements of engine oil: Functions of engine oil: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. Advanced technology can convert natural gas into crystal-clean fully synthetic base oil, to which unique power cleaning technology is added, creating lubricants with superior cleaning and protective performance. Requirements for engine oil: As a type of machinery, engines have common requirements for lubricants similar to general machinery, such as appropriate viscosity, certain anti-oxidation, anti-wear, anti-corrosion, and viscosity-temperature properties.

What Causes the High Water Temperature in BYD Vehicles?

The reasons for high water temperature in BYD vehicles include: 1. Cooling fan not working: The cooling fan may be controlled by a temperature control switch or a water temperature sensor. 2. Radiator blockage: External blockages should be removed with water or air; internal blockages can affect coolant circulation and create pressure, leading to two possible outcomes—either radiator leakage or particularly high water temperature during high-speed driving. 3. Water pump failure: The impeller may slip or jam, causing the timing belt to break, or the impeller may become deformed. 4. Cylinder damage: Combustion chamber and water channel issues may cause water or white smoke to discharge from the drain pipe, leading to frequent radiator water shortage; water channel and oil channel issues (oil mixed with water turns white); water channel and water channel issues, resulting in poor cylinder heat dissipation, especially noticeable at high speeds; or water channel blockage.

Can the Mercedes-Benz E300 be equipped with a car refrigerator?

The Mercedes-Benz E300 can be equipped with a car refrigerator. Below is the relevant introduction of the Mercedes-Benz E300L: 1. Exterior: The Mercedes-Benz new E-Class long-wheelbase version has no changes compared to the imported E-Class, except for some adjustments made to the body length, width, and wheelbase to cater to the Chinese market. The domestic Mercedes-Benz E-Class long-wheelbase version has a body length of 5012mm, with the wheelbase extended by 140mm to 3014mm, and the body width slightly increased by 1mm. 2. Interior: The dark gray interior appears relatively youthful, paired with brown seats, giving a high-end feel. The focal point on the upper part of the center console is the large-size GPS navigation screen, which is impressive enough. The middle section consists of audio control buttons, while the lower part houses the air conditioning control buttons.

What causes the Volkswagen Tiguan to fail to start and display a brake fault?

Reasons and solutions for the illuminated brake system fault light in a car: 1. Severely worn brake pads: Brake pads come in two types—those with sensor wires and those without. For those with sensor wires, when the brake pads wear down to the limit, the sensor wire automatically completes the circuit, triggering the fault light. The brake pads need to be replaced. 2. Low brake fluid level: Insufficient brake fluid is often accompanied by noticeably reduced braking power, and in severe cases, a complete loss of braking force. In this situation, the warning light will illuminate. Simply replenishing the brake fluid in time will resolve the issue. 3. Brake system oil leakage or false alarm: This directly affects the car's technical performance, leading to wastage of lubricating oil and fuel, reduced power efficiency, compromised vehicle cleanliness, and environmental pollution. The fault light will turn on, and the issue can be resolved by replacing gaskets or seals.

Does changing the front grille in 2021 require registration?

In 2021, changing the front grille does not require registration. Relevant information: 1. Regulatory basis: According to the "Motor Vehicle Safety Technical Inspection Items and Methods," the Ministry of Public Security will adjust the annual vehicle inspection items, with the new regulations taking effect on January 1, 2021. The adjustments for private vehicle inspections under the new regulations include: Adding an inspection step: In the online verification items, a "safety defect recall" step is added, meaning that during online verification, if a vehicle has safety issues under recall, the staff will notify the owner of the recall status. 2. Expansion: Clarifying the scope of appearance inspection: The new regulations explicitly state that modifications to the front grille, wheels, roof racks, side steps, and bumpers are allowed. This means that after the implementation of the 2021 new regulations, modifying the front grille within reasonable limits—without changing the vehicle logo, body color, etc.—does not require registration.

When visibility is less than 50 meters in foggy conditions, how many meters should be maintained from the vehicle ahead?

When visibility is less than 50 meters in foggy conditions, a distance of 50 meters should be maintained from the vehicle ahead. Here are some tips for driving in foggy conditions: 1. Regulations: Traffic police state that the "Road Traffic Safety Law" clearly stipulates that in severe weather conditions such as heavy fog, drivers should promptly turn on the fog lights on their vehicles to make their vehicles visible to other drivers. If the vehicle is not equipped with fog lights, the small lights and daytime running lights should be turned on even during the day. 2. Fog lights: When visibility is less than 1 kilometer in foggy conditions, headlights and rear fog lights must be turned on. Turning on the headlights is not only for seeing the vehicle ahead but also for alerting the vehicle ahead. It is best not to use high beams at night in foggy conditions. 3. Speed: Experts recommend that when visibility is less than 500 meters but more than 200 meters, the speed should not exceed 80 kilometers per hour.
