Methods to distinguish between China IV and China V standards in vehicles: Check the fuel consumption label on the new car: The fuel consumption label is usually affixed to the side window of a new car. It indicates the fuel consumption under urban, suburban, and combined driving conditions for light-duty vehicles. Check the vehicle identification plate for the model number: Locate the engine model number on the new car, then visit the Motor Vehicle Environmental Protection Website. Enter the vehicle model number and engine model number to query whether the vehicle meets China IV or China V standards.

As an average car owner, I often encounter this issue. Distinguishing between China IV and China V emission standards is actually quite straightforward by checking a few everyday details: First, inspect the environmental label on the windshield—it usually clearly states whether it's China IV or China V, with China V labels often being more prominent. Second, check the production date; the China V standard was generally implemented starting in 2017, so if the car was manufactured in 2016 or earlier, it's likely China IV, while post-2017 models are mostly China V. Third, refer to the vehicle's user manual or Certificate of Conformity, which directly specifies the emission level. Fourth, input the Vehicle Identification Number (VIN) into free online decoders—the 10th character indicates the year, with 2015-2016 models mostly corresponding to China IV. Once identified, consider the subsequent impacts, such as China V vehicles passing annual inspections more smoothly in certain cities and facing fewer regional driving restrictions. If still unsure, contacting the dealership for verification is an option.

After working in the repair shop for a long time, I've learned that distinguishing between China IV and China V standards requires some professional skills. Simply connect an OBD diagnostic tool to the vehicle's port and read the emission data—the parameter differences become obvious at a glance. China V vehicles have stricter emission limits, with significantly lower nitrogen oxides in the exhaust. Alternatively, you can decode the VIN: if the 10th character represents the year 2017 or later, it's most likely a China V vehicle. Another method is to check the emission control unit in the engine compartment—China V vehicles often come equipped with DPF particulate filters and advanced catalytic converters, making the structure more complex. This is crucial for repairs, as working on China V vehicles may require more labor hours, but it saves customers from environmental fines. For imported vehicles, check the import certificate to confirm the standard. Never rely on guesswork—making a mistake could cost the customer money.

As an environmental advocate, I believe distinguishing between China IV and China V standards is crucial for the environment. It mainly involves checking labels or production dates, with China V standards having lower pollutant emissions. Choosing vehicles with higher standards can help reduce smog and improve air quality. Every time a friend buys a car, I remind them to check the vehicle certificate or look up the VIN online. Upgrading to China V is progress, and I support green transportation.

As a seasoned buyer of used cars, distinguishing between National IV and National V standards must be precise. First, check the seller's maintenance records or insurance policy to see if the emission level is noted. During the test drive, open the engine to listen to the sound and smell the exhaust—National V runs quieter and cleaner. Vehicles produced after 2017 are usually National V, but to be safe, verify with a VIN decoding app. Otherwise, the transfer process might get stuck, especially in restricted zones. I recommend testing the exhaust values before purchase—National V levels are significantly lower, saving you money and hassle.

Why can't the Haval H2 start with one key?

Haval H2's one-key start not responding is generally due to situations such as a depleted smart key battery, insufficient battery voltage, or not shifting the gear back to the P/S position when parking. Below are the related explanations for the failure to start with one key: Depleted smart key battery: This situation is most likely due to a depleted smart key battery, where the start system cannot detect the weak radio waves emitted by the smart key. It is recommended to place the smart key on the start button and then press the button to start. Insufficient battery voltage, no power, or battery damage: Failure to start may be caused by a depleted battery due to reasons like leaving the headlights on for an extended period or the battery reaching the end of its lifespan. Generally, the battery should be replaced in time according to the maintenance manual. If the battery is dead, you can use another battery to start the car or find a few people to use the universal push-start method.

Where is the USB port on the Baojun 730?

The USB port on the Baojun 730 is located next to the cigarette lighter in front of the gear shift lever. Below is an introduction to the usage and precautions for the USB interface: Function of the USB interface: Utilizing the standard power supply in the car, the USB interface can charge DC-5V electrical devices or serve as a fixed power supply interface for electrical equipment. The USB interface, as part of the vehicle's transmission line, offers advantages such as fast transmission speed, ease of use, support for hot-swapping, flexible connectivity, and independent power supply. Precautions for using the USB interface: Charging should only be done when the car's engine is running to avoid damage to electrical devices due to unstable power supply. Avoid connecting too many devices to prevent overloading, which could damage the car's battery and alternator.

How to Understand Car Tire Pressure?

How to know the tire pressure of a car? The methods are as follows: We can determine whether the tire pressure is normal based on the contact condition of the tire tread. By visually observing the number of tire treads in contact with the ground, if the number of treads in contact matches the number we previously recorded under normal tire pressure, then the tire pressure of our car is normal. If the number of treads in contact is more than this, it indicates that the tire pressure is too low; if it is less, it means the tire pressure is too high. The number of treads in contact under normal tire pressure varies for different cars. For one car, the normal number of treads in contact is 3-4. If the number exceeds 4, it means the tire pressure is too low; if it is fewer than 3, it indicates the tire pressure is too high. Under normal circumstances, when observing the tire at normal pressure, visually estimate the contact area between the tire and the ground from the side. A 375px contact area is under normal tire pressure and can be used as a benchmark. If it is less than 375px, the tire pressure is too high; if it is more than 375px, the tire pressure is too low.
