Vehicles from 2012 are generally classified as China IV emission standard, with a small portion meeting China V standards. The methods to determine China IV emission standards are as follows: 1. The simplest and most direct way is to check the vehicle's environmental protection label, which has a clear mark on the back. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Bring the vehicle registration certificate (original or copy) to the vehicle management office for inquiry. 4. For new vehicles, check the vehicle's factory certificate of conformity. Generally, the vehicle's certificate of conformity is kept at the vehicle management office. A rough distinction can be made based on the year of vehicle registration: 1. Vehicles registered after 2015 are mostly China V. 2. Vehicles registered after 2008 are mostly China IV. 3. Vehicles registered in 2007 may be either China III or China IV. 4. Vehicles registered before 2007 are mostly below China IV, i.e., China II or China III. 5. Vehicles registered before 2005 are mostly China II.

I think most cars from 2012 meet the China IV emission standard, because the country began enforcing China IV in some regions from 2010 and implemented it nationwide by 2013, but new cars produced in 2012 generally already met the standard. China IV requires stricter exhaust control, such as gasoline with sulfur content below 50ppm, reducing nitrogen oxide and particulate emissions. At that time, automakers upgraded catalytic converters and engine management systems, adding OBD monitoring functions to diagnose emission issues in real time. If you paid attention when buying a car, dealers would usually highlight this environmental feature. The verification method is simple: check the environmental label on the windshield or the mark on the engine nameplate. Some remote vehicle models might have delayed implementation, but urban cars mostly comply with China IV. Knowing this is helpful for used car transactions, as certain cities restrict vehicles below China III.

How to Fix No Air Coming from Front Car Air Vents?

Check if the vent switch is properly connected and whether there is any short circuit. Check if the air conditioning fuse has blown. The air conditioning fuse is located in the car's fuse box. Simply pull it out and replace it with a new one. Check if the air vents are blocked. If they are, remove the blockage to clear the obstruction. Check if the air conditioning blower motor is functioning properly. Normally, you should hear a humming sound. If it's faulty, replace it with a new one. Check if the cabin air filter is clogged. If the cabin air filter hasn't been replaced for a long time, it may result in no air coming from the vents. Simply remove and replace the cabin air filter.

What is the solution for a car key battery drain issue?

Determine if the car key's battery drain has persisted for more than five days. If it has, it is recommended to directly visit a 4S shop to have a new key made. Use a screwdriver to remove the screws on the car battery casing, open the key cover to expose the internal circuit board and button battery. Use a low-power hair dryer to dry the circuit board, and employ a multimeter to check if the circuit is functioning normally. Replace the old battery with a new branded battery. Be sure to choose a higher-quality battery for longer usage time. Reassemble the car key following the original steps, then test if it works properly and if the key continues to experience battery drain.

What causes the severe insufficient range of Dongfeng Fengxing S50EV?

Dongfeng Fengxing S50EV's severe insufficient range is mainly due to battery lifespan degradation. The driving mode negatively impacts the battery, leading to shortened lifespan. Unstable charging environments cause additional damage to the battery. The impact of air resistance: Air resistance is the most energy-consuming factor during vehicle movement. The higher the speed, the greater the air resistance. At high speeds, air resistance acts like a wall blocking the vehicle's progress, forcing the car to expend more energy to maintain speed, inevitably affecting the range. Speed and air resistance are interdependent - vehicle speed and wind force are direct influencing factors, so never underestimate their impact on range, which can outweigh air conditioning consumption. The effect of weight on range: Vehicle weight undoubtedly has a distinct impact on range, as does air conditioning energy output. Temperature affects battery chemistry - cold weather inevitably reduces range and slows charging, unavoidable inherent factors.
