What does 91V on a tire mean?

91V on a tire refers to the load index and speed rating. 91 represents the load index, indicating a maximum load capacity of 615Kg per tire, while V signifies that the tire's maximum allowable speed is 240km/h. Below are specific details about car tire specifications: 1. Specification model representation: Tires are crucial components of vehicles, with various specification models suitable for different vehicle types. The specification model identification is typically found on the tire sidewall, represented by a series of alphanumeric characters corresponding to the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. 2. Speed rating: Based on different maximum speed capabilities, tire speed ratings are categorized into various levels from A-Z, with level A further divided into eight sub-levels from A1-A8. The later the letter representing the tire speed rating appears in the alphabet, the better the tire's performance.

Where is the child lock located on the car door?

Child locks are typically located in the window button area on the driver's side door or along the inner edge of the rear doors. Here are the specific details about child locks: 1. How to use: When you need to activate the child safety lock, first open the rear door, gently push the small lever below the door lock towards the direction with the child icon, then close the door. 2. Function: When the child safety device is locked, the door can only be opened from the outside, and the interior door handle temporarily loses its function to open the door. When the car child safety lock is engaged, even if the central locking system is unlocked, the door will remain locked and can only be opened from the outside. If you find that the rear door cannot be opened from inside the car while it opens normally from the outside, check if the child safety lock has been accidentally activated.

What does the AFS warning light indicate?

AFS stands for the Adaptive Front-lighting System warning light. Here are the specific details about the adaptive front-lighting system: 1. Function: The Adaptive Front-lighting System (AFS) adjusts the direction of the headlight beams according to current driving conditions. The system moves the headlight beams left or right based on vehicle speed and steering wheel angle, working in conjunction with the automatic headlight beam adjustment system to improve visibility at intersections and during turns. 2. Turning off the AFS system: The system activates when the vehicle speed exceeds 10 km/h. It operates within the maximum range of the steering wheel angle. If you do not wish to activate the system, press the "AFS OFF" button to turn it off. To turn it back on, press the button again. When the system is off, the "AFS OFF" indicator on the instrument cluster will illuminate. If there is a malfunction in the system, the "AFS OFF" indicator on the instrument cluster will flash.

What are the differences between gasoline engines and diesel engines?

Here are the specific differences between diesel engines and gasoline engines: 1. Fuel supply and ignition method: In diesel engines, fuel mixing and combustion occur inside the cylinder. High-pressure diesel is directly injected into the combustion chamber by the fuel injector, mixes with air to form atomized gas, and then ignites after compression. Therefore, in terms of structure, gasoline engines have an additional complete ignition system compared to diesel engines. In gasoline engines, gasoline from the fuel pump mixes with air from the air filter in the carburetor to form a combustible mixture, which enters the cylinder combustion chamber through the intake manifold and is ignited by an electric spark. 2. Fuel: Diesel engines use diesel fuel. The cetane number is an indicator of the self-ignition performance (combustibility) of diesel fuel, while the distillation range represents its volatility, and viscosity measures fuel fluidity. Gasoline engines use gasoline. Knocking is an abnormal self-ignition phenomenon that may occur during gasoline engine combustion as the compression ratio and cylinder gas temperature increase. A higher octane number indicates stronger anti-knock capability, allowing for higher compression ratios. Anti-knock additives, commonly lead compounds, are often added, making gasoline more lead-containing. 3. Corrosion resistance: Diesel engine main bearings and connecting rod bearings use high-performance materials like lead bronze or lead alloys, which have relatively poor corrosion resistance. Gasoline engine main bearings and connecting rod bearings can use softer materials with better corrosion resistance, such as Babbitt metal.
