There are generally four methods. First: Check the back of the vehicle's environmental protection compliance label, which indicates the emission standard. Second: Refer to the vehicle conformity certificate. Third: Determine based on the manufacturing date. Fourth: Inquire at the local vehicle management office. Related Information: Vehicle Emission Standards: Vehicle emission standards regulate the permissible levels of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot). Starting from January 1, 2004, Beijing upgraded its vehicle emission standards from Euro I to Euro II, and by 2008, officially implemented the Euro III standard. China Standards: Compared to advanced countries, China's vehicle emission regulations started later and were initially less stringent. Based on China's actual conditions, a phased implementation approach was adopted from the early 1980s, prioritizing easier measures first. The implementation has mainly been divided into three stages up to now.

Checking the car's emission standard is a piece of cake. For seasoned drivers like me, the easiest way is to flip through the vehicle license. The first page has an environmental protection section that clearly states China IV, China V, or China VI. This matters a lot—it affects urban driving restrictions and annual inspections, especially in big cities where anything below China V might not even enter downtown. For new cars, there's usually an environmental label stuck on the top-left corner of the windshield; you can also scan the QR code to check. No label on an older car? No problem—just call the 4S dealership, provide your license plate number, and they’ll look it up for free, quick and easy. Remember, check your emission label regularly and don’t lose it, or you’ll face a heap of trouble on the road. It’s smart to verify it every six months to avoid getting caught off guard by policy changes.

How to check the emission standard level? My favorite technical method is to download the Autohome APP, enter the VIN code, and get instant results online. The VIN is located at the bottom left of the windshield or on the door frame—just input the 17-digit alphanumeric combination. You can also check on the official website of the environmental protection department by entering the license plate number. Why is this important? Because vehicles with lower emissions are more fuel-efficient, eco-friendly, and can save you money by avoiding high-restriction zones. Don’t forget to compare old and new models—the difference between China 6 and China 5 standards is significant, so always opt for the latest emission-friendly upgrades when choosing. Check occasionally to avoid violations, as these tools are free and easy to use.

What are the main maintenance items for electric vehicles?

Unlike fuel-powered vehicles, the maintenance of pure electric vehicles is relatively simple. Routine maintenance mainly includes: three-electric system inspection, chassis inspection, lighting inspection, and tire inspection. Here are the relevant details: A-Service: Pure electric vehicles don't have engines, so there's no need to change engine oil or oil filters. The most common "minor service", also called "A-Service", is just routine inspection. The inspection cost varies slightly depending on the brand and region. Based on the calculation of one A-Service plus one B-Service per year for pure electric vehicle maintenance, A-Service only involves inspection. B-Service: B-Service requires replacement of brake fluid, coolant, or reducer gear oil, and these three fluids generally don't need to be changed simultaneously. Therefore, pure electric vehicle maintenance requires an average of two services per year (two inspections + one fluid replacement).

Under what conditions is fast idle used for the engine?

Fast idle, also known as high idle, refers to an idle speed that is higher than the normal idle speed. It is used during cold starts to help the engine quickly reach its optimal and most economical working environment, increasing the engine's idle speed and accelerating warm-up. Here is a related introduction: Idle speed: For an engine with good performance, the idle speed is generally between 650-800 RPM. Fast idle is typically around 1000 RPM. Fast idle: Fast idle refers to the higher engine speed compared to normal idle when starting a cold engine to help it reach operating temperature more quickly. Simply put, it is an engine speed higher than the normal idle speed. The control conditions mainly involve sensors such as the intake air temperature sensor or coolant temperature sensor.

Additionally, Bridgestone tires are OEM manufactured at Yongsheng. Shandong Yongsheng Rubber Group Co., Ltd. is located in the Rubber Industrial Park of Dawang Town, Guangrao County, China. The company was established in 1986 and integrates development, production, and sales. If you want to replace the tires yourself, you can follow the steps below: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car. The jack should be positioned under the vehicle, check and ensure the jack is at a right angle to the ground; Remove the hub cover, loosen the nuts counterclockwise. Do not completely loosen the nuts, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts, not the tire, are turning; Turn the nuts counterclockwise until they are loose. Repeat this step for all lug nuts, then completely remove the nuts; Place the new tire on the hub, carefully align the tire rim with the wheel bolts, install the lug nuts, and tighten them by hand until all nuts are concealed. At this point, the tire replacement is complete.

Why does the auto start-stop system still activate when the brake is pressed?

Start-stop systems operate based on the battery's charge level. If multiple electrical devices in the vehicle are turned on, the engine may start working after a few seconds. Here's an introduction to auto start-stop knowledge: 1. Limitations: The use of auto start-stop function is subject to certain conditions. It won't function properly if the car battery has insufficient charge, if the battery temperature is too high or too low, or if seat belts aren't fastened during driving. 2. Working Principle: By installing an enhanced motor with idle start-stop capability in traditional engines, the system completely shuts off the engine when idle stop conditions are met. When needing to move again, the idle start-stop motor quickly responds to the driver's command, rapidly restarting the engine to reduce fuel consumption and exhaust emissions.

How Many Years Can Snow Tires Be Used?

Under normal circumstances, snow tires can be used for up to 4 years. If tires have been used for more than four years, extra caution is required. If you wish to continue using them, ensure that the tires still maintain adequate performance. However, if the tires show significant wear or aging, it is recommended to replace them promptly to avoid dangerous situations such as blowouts. Below are the relevant details: Usage Cycle: The service life of snow tires is typically 3-4 years or 50,000-60,000 kilometers. This means that when either of these parameters is reached, the tires should be replaced. However, in practice, the actual condition of the tires should also be considered. You can have them inspected at a repair shop to determine whether they are still safe for continued use. Advantages of Snow Tires: Compared to regular tires, snow tires feature a special tread compound and tread pattern technology. The unique compound increases friction between the tire and the road, enhancing safety when driving on snow or ice. When temperatures drop, the rubber in regular tires tends to harden, reducing their performance. Snow tires, on the other hand, become softer, providing better grip and improving vehicle control and safety on slippery icy surfaces.

What Happens When the Chassis is Scraped?

It may cause the hazard of the car chassis bottoming out. This is because after road obstacles scratch the chassis, some components of the chassis may become deformed, especially parts like the upper and lower control arms and tie rods which are prone to deformation. Here are the relevant details: Potential damages: After the car's chassis is scraped, there's a risk of bottoming out, and it may also damage the vehicle's fuel lines. The engine oil pan might leak, rendering the car unusable until repaired at a maintenance shop or 4S store. Methods to protect the chassis: To prevent damage to the car's chassis, you can opt to spray a chassis armor coating. This layer of armor protects the car's chassis, not only preventing impacts from stones but also offering anti-corrosion benefits. Another option is installing an engine guard. Typically, engine guards used in cars are customized according to different vehicle models. The primary purpose of an engine guard is to protect the engine from damage, followed by shielding it from external factors. Not all car models come with an engine guard; this depends on the specific vehicle model.
