The function of the grille is to close when the engine temperature is relatively low, which accelerates the engine's warming speed and reduces exhaust emissions. Closing the grille when the engine temperature is low can also reduce wind resistance and improve fuel economy. Active grilles are automatically controlled and do not require manual operation by the driver. The active grille is located at the front of the car and consists of adjustable louvers that can control the opening angle. It maximizes the car's air intake efficiency and cooling efficiency through computer-controlled adjustments. In most vehicle models, the grille remains permanently open, which ensures that the engine receives maximum cooling power as soon as the car is started.

What are the motor vehicle inspection regulations?

Small and micro non-commercial passenger vehicles must be inspected once every 2 years within the first 6 years; after 6 years, they must be inspected once annually; after 15 years, they must be inspected twice a year. Below are the specific details of vehicle annual inspections: 1. Meaning of annual inspection: Vehicle annual inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates, equivalent to an annual physical examination for the vehicle according to the "Safety Technical Conditions for Motor Vehicle Operation." 2. Exemption policy: Non-commercial small private passenger vehicles with 7 seats or fewer are exempt from on-site inspections for the first 6 years. However, owners still need to pass an exhaust emission test within the specified period (usually every 2 years) and apply for an inspection compliance mark at the vehicle management office, motor vehicle registration service station, or traffic police substation, which must then be affixed to the upper right corner of the vehicle's front windshield. 3. Applicability of the exemption policy: The 6-year exemption policy for non-commercial passenger vehicles and similar vehicles has been in trial implementation since September 1, 2014. Vehicles registered on or after September 1, 2012, are eligible for 2 exemptions; those registered between September 1, 2010, and August 31, 2012, are eligible for 1 exemption; vehicles registered before August 31, 2010, must still follow the original inspection regulations for annual review procedures.

Can a cracked rear car bumper be repaired?

It is possible to repair a cracked bumper. Here is an introduction to bumper repair: Methods for repairing a bumper: A plastic welding gun can be used for repair by heating and melting the plastic welding rod and the surface of the film to achieve melting and bonding. However, for some larger cracks, the buffering effect cannot be guaranteed after repair, and it can be directly replaced. Function of the bumper: Car bumpers serve purposes such as safety protection, vehicle decoration, and improving the aerodynamic characteristics of the vehicle. From a safety perspective, they can provide a buffering effect during low-speed collisions, protecting the front and rear body of the car; they can also offer some protection to pedestrians in the event of an accident.

How to Determine Liability in a Three-Car Rear-End Collision?

In determining liability for a three-car rear-end collision, the traffic police department must conduct an on-site investigation to make a comprehensive judgment: If the third car hits the second car, causing the second car to hit the first car, then the third car bears full responsibility. The principles for liability division in rear-end collisions are as follows: Rear car hits the front car in motion: In such a rear-end collision, the rear car bears full responsibility; Front car reverses or rolls back and hits the rear car: In such a rear-end collision, the front car bears full responsibility; Front car stops on the road without complying with regulations: If the front car fails to turn on the hazard warning lights and set up warning signs as required, resulting in a rear-end collision, the front car bears secondary liability, while the rear car bears primary liability; Front car stops on the road in compliance with regulations: If the front car turns on the hazard warning lights and sets up warning signs as required, resulting in a rear-end collision, the rear car bears full responsibility; Front car is overlength: If the front car does not set up obvious warning signs as required, resulting in a rear-end collision, the front car bears secondary liability, while the rear car bears primary liability; Front car lacks taillights at night: In such a rear-end collision, the front car bears secondary liability, while the rear car bears primary liability.

What Does Vehicle Model Number Mean?

Vehicle model number is a tool for identifying a specific type of vehicle. Its structure is divided into three parts: beginning, middle, and end. The beginning represents the manufacturer, the middle represents the vehicle type code, main parameters, and product serial number, while the end represents the enterprise-defined code. Unlike an ID card that identifies individuals uniquely, it has the characteristic of uniformly defining the same type of vehicles. Below is the detailed introduction: Beginning - Enterprise Code: The enterprise code is generally the initials of the Chinese pinyin, represented by two or three letters. For example, SGM stands for Shanghai General Motors, CA represents FAW, EQ represents Dongfeng (Second Automobile Works), BJ represents Beijing, etc., reflecting the manufacturer or brand. Middle - Category Parameters: The first Arabic numeral in the middle part represents the vehicle type: 1 for trucks, 2 for off-road vehicles, 3 for dump trucks, 4 for tractors, 5 for special vehicles, 6 for buses, 7 for cars, and 9 for semi-trailers. Main parameters include car engine displacement, bus length, truck gross weight, etc. End - Custom Code: The end part mainly consists of letters and Arabic numerals, generally used by enterprises to distinguish their own developed products. For example, BMW has Series 1, Series 2, Series 3, A-Class, B-Class, C-Class, etc. It should be noted that the letters 'i', 'o', and 'q' are not allowed in vehicle model numbers as they can easily be confused with other numbers, making precise identification difficult.
