Here is a detailed introduction to the new regulations for the 2021 vehicle inspection: 1. Three new additions: (1) Tread depth inspection: This inspection is conducted using a tire tread depth gauge. If the tire is severely worn and the depth does not meet the standard, the vehicle will fail the annual inspection. (2) Vehicle wheelbase inspection: The wheelbase test has been added to prevent private modifications by owners. Modifying the wheelbase is illegal and should not be attempted. (3) Vehicle lifting device: This addition allows for a clearer observation of the vehicle's chassis condition, such as extended wheelbases, which can be easily identified. 2. Five removals: (1) Elimination of electronic parking brake inspection: Due to variations in vehicles and inspectors, multiple scenarios could arise during electronic parking brake inspections. (2) Elimination of headlight deviation inspection: If the headlights are not replaced, deviation issues are unlikely. The new regulations cancel this test, but measurements of low beam, high beam brightness, and color temperature will still be conducted. (3) Elimination of speed detection: There is no longer a need to detect the speedometer's indication error on rollers. Modern LCD dashboards display a wide range of information, and the speed shown is generally very accurate. (4) Elimination of speedometer error detection: The vehicle speed inspection item has been removed, and there is no longer a need to detect the speedometer's indication error on rollers. (5) Elimination of vehicle noise inspection and suspension test: With the addition of lifting devices, it is possible to observe whether the suspension has any issues when the vehicle is lifted.

As a long-time car owner, I find the 2021 annual inspection regulations quite practical. The most noticeable change is the expanded exemption scope. For instance, my regular passenger car is now exempt from annual on-site inspections for the first six years, requiring only an online application for the inspection decal every two years—saving time, effort, and costs. Gone are the days of waiting in long queues; now it’s just a few taps on my phone at home. Vehicles under 10 years old now require biennial inspections, shifting to annual checks only after a decade. New energy vehicles, like electric cars, have even simpler inspections, with a focus on battery safety. The inspection process has also been streamlined, cutting unnecessary steps, though emissions testing is stricter to ensure compliance. I think this policy balances modern convenience with encouraging proper vehicle maintenance, reminding owners not to neglect safety despite the exemptions. Overall, it feels very user-friendly.

How to turn off the eco mode in the car?

The method to turn off the eco mode in the car is: adjust the square button below the dashboard brightness, switch to the eco on interface, and long press to turn it off. The working principle of the eco mode is: by changing the gear shifting time of the transmission and the sensitivity of the accelerator pedal, the output power of the air conditioning system is changed. The eco mode can be divided into: 1. Active eco driving mode: there is a special button, and the owner can choose whether to turn it on or not. After turning it on, a series of settings about driving will change; 2. Non-active eco driving mode: there is no special button, and it has the function of reminding and guiding.

Why Does the Engine Keep Stalling?

Engine stalling is caused by: 1. Blocked fuel supply lines in the engine; 2. Excessive carbon buildup on the spark plugs in the cylinders; 3. Use of low-quality fuel. Solutions for engine stalling include: 1. Cleaning the engine's fuel supply lines; 2. Replacing with suitable fuel; 3. Cleaning the spark plugs in the cylinders. An engine is a machine that converts other forms of energy into mechanical energy, categorized into: 1. Internal combustion engine: Fuel burns inside the engine; 2. External combustion engine: Fuel burns outside the engine; 3. Gas turbine: Combustion produces high-pressure gas, which drives the turbine blades to rotate; 4. Jet engine: Generates thrust directly by expelling high-speed gas from the nozzle.

What is the working principle of hybrid electric vehicles?

The working principle of hybrid electric vehicles is: combining fuel and electric power, where the electric motor delivers strong torque at low speeds to provide power for vehicle start-up and acceleration, while the internal combustion engine's output power and torque increase with rising speeds, supplying power for mid-to-late stage acceleration. The types of hybrid electric vehicles include: 1. Micro hybrid; 2. Mild hybrid; 3. Moderate hybrid; 4. Full hybrid. Examples of hybrid electric vehicles are the Toyota Prius, Leiling Hybrid, Corolla Hybrid, Camry Hybrid, Kia Niro, and Honda CR-V Hybrid.

How to Jump Start a Car Battery?

The method to jump start a car battery is: 1. Connect both ends of the prepared red jumper cable to the positive terminals; 2. Connect both ends of the black jumper cable to the negative terminals, ensuring that the metal wires do not touch the car body to prevent short circuits. The maintenance methods for a car battery are: 1. Avoid parking the car in an open parking lot for extended periods; 2. Each engine start should not exceed 5 seconds, with a minimum interval of 15 seconds between subsequent starts; 3. Regularly charge the car battery; 4. Clean the battery terminals periodically and apply special grease to protect the wiring harness; 5. Avoid using car electrical appliances after the engine is turned off.

What is a Start-Stop Battery?

A start-stop battery refers to a type of battery that allows a car to automatically shut off the engine when temporarily stopped and restart it when the car moves forward. Its functions include energy saving, emission reduction, and lowering exhaust emissions. Start-stop batteries are categorized into EFB and AGM. Situations where the start-stop function should be turned off include: 1. congested road sections; 2. uphill or downhill driving; 3. when the air conditioning is in cooling mode; 4. driving through waterlogged sections; 5. low-speed parking. Car batteries, also known as storage batteries, serve the following purposes: 1. providing a strong starting current to the starter when starting the engine; 2. assisting the generator in supplying power to electrical equipment when the generator is overloaded.
