Viewing the vehicle's environmental protection label is the simplest and most direct way to check its national emission standard. You can also inquire through the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center. Below is relevant information about vehicle emission standards: 1. Meaning of vehicle emission standards: Vehicle emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). 2. Meaning of National VI: The National VI standard for motor vehicle pollutant emissions is established to implement the "Environmental Protection Law of the People's Republic of China" and the "Air Pollution Prevention and Control Law of the People's Republic of China," aiming to prevent pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health.

As an average car owner, if you want to know your vehicle's emission standard, simply check the vehicle registration certificate—it will clearly indicate the standard, such as China 5 or China 6. In the past, there used to be an environmental label on the windshield, but now it’s simplified, and the registration certificate is the most reliable source. Additionally, the compliance certificate provided by the dealer at the time of purchase also states the standard. With today’s technology, you can quickly check the results by entering the VIN (Vehicle Identification Number, usually located at the lower left corner of the windshield) into mobile apps like Autohome or the Traffic Management 12123 app. Knowing your emission standard is crucial, especially in major cities with restricted zones—China 3 vehicles, for example, aren’t allowed in during daytime, so route planning is essential. If you lose the documents, don’t panic—just visit the vehicle management office for a replacement or check online. Emission standards are upgraded frequently, so staying updated helps the environment, as high-pollution vehicles impact air quality. Remember these tips for a hassle-free and safe experience.

What is the normal idle speed for the new Santana?

The new Santana can idle normally at 600 rpm, and the normal idle speed should be within 1000 rpm. Under normal circumstances, the idle speed is around 700 rpm. Generally, it ranges between 700 to 800 rpm. Introduction to Car Idle Speed: When the engine runs without load, it is called idling. When the accelerator pedal is fully released while the engine is running, the engine enters the idle state. The engine speed during idling is referred to as the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Generally, the optimal idle speed is the lowest rpm at which the engine does not vibrate. Function of Car Idle Speed: Avoiding unnecessary work—Idling overcomes the engine's own operational resistance and maintains the minimum engine speed, providing convenience for drivers in various driving conditions and temporary stops. For example, when waiting at traffic lights or in congested traffic areas, even for short durations, temporarily turning off the engine can achieve immediate energy-saving and emission-reduction effects.

What is the difference between Repsol Moto Racing 10w50 and 10w40?

Compared to 10w40, 10w50 has higher oil viscosity and better sealing performance, but the engine will consume more fuel. At idle, higher oil viscosity results in lower noise, while at driving conditions, higher viscosity oil produces higher noise. Lower viscosity oil, on the other hand, is characterized by fuel efficiency. Generally, 40 is suitable for all seasons, while 50 is more appropriate for large-displacement vehicles in summer. The related details are as follows: 1. Protection: The oil grade is not related to its quality but represents the viscosity grade of the oil. The 'W' in the grade stands for Winter, and the number before it indicates the oil's low-temperature fluidity. The smaller the number, the better the low-temperature fluidity. The number after 'W' represents the oil's viscosity grade at 100°C. The larger this number, the better the protection the oil provides to the engine at high temperatures. 2. Viscosity characteristics: Oil 10w40 means the oil's viscosity is 10w40. The number before 'W' represents cold-start performance. The smaller the number, the easier it is to start the engine in cold weather. Common grades include 0W, 5w, 10w, and 15w. The number 40 indicates the oil's viscosity characteristics at high temperatures. High-viscosity oil (with a higher value) may be more suitable for high-speed driving or heavy-load vehicles.

What are the differences between BMW and Mercedes-Benz?

Design philosophy differences: There is a popular saying: 'Drive a BMW, ride a Mercedes-Benz,' which illustrates the difference in design philosophy between the two brands. BMW emphasizes driving dynamics, while Mercedes-Benz focuses more on comfort. Therefore, BMW excels in handling but is slightly less comfortable than Mercedes-Benz. Interior design differences: Mercedes-Benz places great emphasis on the luxury of its interiors. From the driver's perspective, Mercedes-Benz interiors appear more luxurious. In contrast, BMW interiors prioritize practicality. For example, many Mercedes-Benz models feature an additional quartz clock, which, although not very practical, enhances the perceived premium feel. BMWs display an electronic quartz clock on the dashboard, but Mercedes-Benz's design approach gives it a more upscale appearance.

Is it necessary to buy a four-wheel drive Sienna?

Toyota Sienna is recommended to buy the four-wheel drive version if the budget allows, as the four-wheel drive Sienna model has more advantages when climbing slopes or driving on slippery roads such as rain and snow. Introduction to Part-Time Four-Wheel Drive: Part-time four-wheel drive is a system where the driver can manually choose between two-wheel drive and four-wheel drive. The driver can achieve two-wheel or four-wheel drive by disconnecting or connecting the transfer case according to driving needs. This is also the most common four-wheel drive system for off-road vehicles or SUVs with four-wheel drive function. Introduction to On-Demand Four-Wheel Drive: On-demand four-wheel drive is a system that only engages four-wheel drive when necessary, otherwise it remains in two-wheel drive. Its emergence not only reduces the cost of building four-wheel drive vehicles but also provides users with good fuel economy. Mass-produced mainstream SUVs like the Honda CR-V and Toyota RAV-4 are equipped with on-demand four-wheel drive systems.
