Check the vehicle's factory certificate or vehicle conformity certificate. Symbol markings: The symbols for China 1 to China 6 standards are I, II, III, IV, V, and VI respectively. China first introduced the China 1 emission standard on July 1, 2000. As it was based on European emission standards and aligned with international norms, Roman numerals were adopted for the China 1 to China 6 markings. New emission standards have been introduced every few years since then. China VI standard: The "China VI standard" is divided into two phases: "China VI a" and "China VI b", with nationwide implementation planned for July 1, 2020 and July 1, 2023 respectively. However, the China VI standard is extremely stringent, far exceeding Europe's Euro 6 and America's Tier 3 standards, making it one of the strictest emission standards globally. The implementation period for China VI standards will also be longer.

If you want to know where to check the China VI emission standard, as an ordinary car owner, I’d like to share some practical tips. The most straightforward method is to check the vehicle’s Certificate of Conformity, which usually comes with the car—the emission standard like China VI-A or VI-B will be clearly stated. The environmental label on the windshield often includes this information as well. If you don’t have it handy, online queries are quite convenient. Visit the official website of the Ministry of Ecology and Environment, navigate to the motor vehicle emission catalog section, and enter the VIN or license plate number to get the results. I’ve also used car apps like Dongchedi, where entering the model immediately displays the emission data. Salespeople will explain this clearly when you buy a car, and it’s even more important to verify this when purchasing a used car to avoid mistakes. Regular checks can confirm your car’s environmental rating.

From a policy understanding perspective, checking the China VI standards is quite straightforward, and I recommend relying primarily on official channels. The Ministry of Ecology and Environment website is the most reliable source, as they maintain a national motor vehicle emissions database. Simply follow the steps to search by vehicle model or VIN, and the emission details will be clearly displayed. The vehicle conformity certificate also includes this essential information. Don’t overlook the environmental label affixed to the corner of the front windshield. Be cautious about trusting third-party websites to avoid misinformation. When selecting a vehicle, always ask the 4S store consultant for documentation to verify details. With the implementation of China VI, emission requirements have become stricter, which also benefits vehicle maintenance by ensuring compliance and proper operation on the road.

How to Start as a Used Car Broker for Beginners?

You need to be able to identify whether it's an accident-involved vehicle, as such cars are tricky in the current market—handling them poorly could lead to losses. At the very least, you should be able to inspect the car's condition by looking, smelling, and listening. Sellers will naturally first inquire about the price of their car from the broker. At this point, the broker should absolutely avoid rushing to lower the price.

How to Drive on a Highway with Only 2 Lanes?

Before entering the highway, the car owner must go to a repair shop or 4S store to check whether the vehicle's condition is normal and whether the tire pressure is normal. The speed should not be too fast, but also not too slow, because there are maximum and minimum speed limits on the highway, and you cannot change lanes back and forth. You cannot always drive on the left side, because the left lane is for overtaking and cannot be used continuously; it should only be used when overtaking.

Where is the Altima air-fuel ratio sensor 1b1 located?

The Altima air-fuel ratio sensor 1b1 is located above the three-way catalytic converter, with the V6 engine B1 air-fuel ratio sensor positioned on the left side. Since the three-way catalyst's purification capacity for CO, HC, and NOx drops sharply once the air-fuel ratio of the mixture deviates from the theoretical value, an oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust. It then sends feedback signals to the ECU, which in turn adjusts the fuel injection volume from the injectors, thereby maintaining the air-fuel ratio of the mixture near the theoretical value.
