Is it necessary to install an in-car air purifier?

What is the working principle of a car air purifier?

The working principle of a car air purifier is as follows: 1. The micro fan (also known as a ventilator) inside the machine circulates the indoor air. 2. The car air purifier is typically composed of a high-voltage generating circuit negative ion generator, micro fan, air filter, and other systems. 3. The polluted air passes through the air filter inside the machine (undergoing dual filtration) to remove or adsorb various pollutants. It then passes through the negative ion generator installed at the air outlet (when operating, the high voltage in the negative ion generator produces direct current negative high voltage). 4. The air is continuously ionized by the negative ion air purifier, which generates a large number of negative ions. These are then blown out by the micro fan, forming a negative ion airflow to achieve the purpose of cleaning and purifying the air.

Can a Vehicle That Cannot Be Transferred Still Undergo Annual Inspection?

A vehicle that cannot be transferred can still undergo annual inspection, but it must be processed under the name of the original owner, and the original owner's ID card is required. For specific details, it is recommended to call the local vehicle management office for inquiries. If a vehicle is not transferred, not only is the annual inspection troublesome, but insurance is also very complicated. If the vehicle is involved in an accident, the insurance company will notify the owner or the user of the vehicle, but the compensation will definitely be paid to the previously designated insured account or beneficiary account. Below is an introduction to the new regulations regarding vehicle annual inspections: 1. Non-commercial passenger cars (including non-commercial small and micro passenger vehicles) are subject to a 6-year exemption policy, meaning new vehicles within 6 years are exempt from on-site inspection. However, note that every 2 years, an application for an inspection mark must be submitted to the traffic management department; otherwise, it will be considered as failing the inspection. SUVs and MPVs with 7 seats or more do not qualify for the 6-year exemption policy. 2. Vehicles registered for more than 6 years are subject to an annual inspection policy; vehicles registered for more than 15 years are subject to a twice-a-year inspection policy.

What is the ECO mode in cars?

ECO refers to the car's economical driving mode function. ECO is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard illuminates, it indicates that the vehicle's economical mode has been activated. Eco mode is categorized into active and non-active types, with the difference being that the active type has a dedicated button, allowing the driver to choose whether to enable it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active Eco mode does not have a dedicated button. When the dashboard Eco indicator light turns on, it merely serves as a reminder function. The Eco mode automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most cars utilize the active Eco driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can enable the Eco mode. However, it is unnecessary to activate Eco mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of Eco mode but also affect the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or in N/P gear and manual mode, the Eco mode may also become ineffective. When a high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function in such scenarios.

Can I pass the annual inspection after installing additional lights?

Installing additional lights without major modifications can pass the annual inspection. Chinese regulations classify the annual inspection of vehicle lights into the following categories: 1. First is the appearance inspection, where the inspector visually checks the vehicle for any unauthorized modifications. As long as the modifications are not excessive, they are generally acceptable. 2. Next is the instrument inspection on the testing line, which mainly focuses on the following aspects of the lights: 1. The color temperature must not exceed 6000K. The testing equipment can only detect light sources with a color temperature below 6000K. 2. Light scattering: The Road Traffic Safety Law stipulates that "vehicle lighting must not affect other road users." 3. Insufficient brightness: During the inspection, the requirement for low-beam headlights is that they must not be less than 1200 lumens. There is only a lower limit for brightness, not an upper limit. This means no matter how bright your headlights are, as long as they do not scatter, it is acceptable.
