What does China V vehicle displacement mean?

[FinnLynn]

China V vehicle displacement refers to the National Fifth Stage Emission Standards for motor vehicle pollutants, with emission control levels equivalent to the Euro 5 emission standards currently implemented in Europe. China V imposes more stringent restrictions on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. From China I to China VI, each upgrade in standards reduces vehicle pollution by 30% to 50%. The China emission standard (e.g., China IV, China V) indicates the total emission level of a vehicle's exhaust pollutants - the higher the number, the higher the standard, and correspondingly the lower the engine emissions. Vehicle emission pollutants include: carbon dioxide, sulfides, nitrogen oxides, fluorochlorohydrocarbons, non-methane total hydrocarbons, etc.

The China 5 emission standard sounds quite impressive, doesn't it? Actually, it's just the latest regulation set by the state for vehicle exhaust emissions, belonging to the fifth phase. Last year when I was doing automotive modifications, I came across many China 5 vehicles. They are strictly controlled, with pollutants like carbon monoxide and hydrocarbons in the exhaust having to be tightly regulated. This standard was uniformly implemented nationwide starting in 2017, so friends buying new cars must check if it complies. The benefit is that there's less pollution when we drive, which is good for the environment! In the used car market now, China 5 vehicles are clearly selling much better. I know a few car dealers who say they make tens of thousands more selling China 5 cars compared to China 4 ones.

What do ordinary folks fear most when buying a car? Failing the annual inspection! Last time I was at the testing station, I saw an old car owner looking miserable because his China IV emission standard vehicle exceeded the limits and couldn't pass. The staff said nationwide checks are strict now, and even new cars must meet China V standards. These standards mainly require manufacturers to properly treat exhaust emissions during production, and I heard they also mandate OBD systems to monitor emission status. I've noticed that besides being eco-friendly, driving China V cars is indeed more convenient in big cities. In places with strict traffic restrictions like Beijing, China V cars can freely access many areas where China IV vehicles are banned.

Speaking of vehicle emissions, I've seen countless cases of excessive pollution during my years in vehicle inspection. The China 5 emission standard is truly meaningful, as it mandates that all newly manufactured vehicles must comply. Specifically, it refers to various pollutants emitted from the exhaust pipe, such as nitrogen oxides, with the upper limit reduced from 0.08g/km under China 4 to 0.06g/km under China 5. When this policy was first implemented in 2017, automotive factories nationwide were extremely busy, as entire production lines had to be revamped. However, it's been worth it in the long run – now when driving, you can clearly feel the urban air quality has improved. The only thing is that owners of older vehicles need to be cautious, as cars below China 4 standards face significant price reductions when reselling.

The most obvious advantage of China V vehicles is saving money and hassle! Both of my cars meet China V standards, and I never refuel at small gas stations. Because compliant vehicles must use better catalytic converters, poor-quality gasoline can easily damage them. There's a veteran mechanic in my neighborhood who has run a repair shop for ten years, and he says the exhaust systems of China V vehicles are over 30% more durable than older models. Specifically, you won't need to replace the purification device for five or six years, saving thousands in repair costs. If you're considering a car change, China V is highly recommended—it also has better resale value.
