What is the emission standard for cars in 2018?
4 Answers
18-year-old cars comply with the China V emission standard. The emission standard for vehicles refers to the requirements that vehicle exhaust emissions must meet. Only new vehicles that comply with the current emission standard can be produced and sold. Vehicles that meet the China V emission standard are referred to as China V vehicles. The China V standard refers to the National Fifth Stage Emission Standard for Motor Vehicle Pollutants, also known as the "China V standard." The emission control level of the China V standard is equivalent to the European Union's fifth-stage emission standard currently in effect. The EU has been implementing this standard since 2009, imposing stricter limits on pollutants such as nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM) emitted by vehicles. From China I to China IV, each upgrade in the standard reduces vehicle pollution by 30% to 50%. Regarding the specific emission standards, they primarily refer to the content of harmful substances in vehicle exhaust emissions, including carbon monoxide (CO), hydrocarbons and nitrogen oxides (HC+NOx), particulate matter (PM), and other harmful substances. To reduce the emission of harmful substances and meet the requirements of emission standards, vehicle manufacturers continuously improve their production technology and exhaust control technology. Examples include engine valve adjustment systems, fuel injection control systems, vehicle exhaust treatment systems, three-way catalytic converters, and particulate filters.
I drive a 2018 model car, and after checking the emission standards, it's generally China V (National 5), because the China VI (National 6) standard wasn't fully implemented at that time, with only a small number of vehicles in pilot areas adopting China VI in advance. Checking this is quite simple—just look for the car's environmental label or enter the VIN online. Lower emissions are better for urban air quality, so I usually opt for cleaner gasoline to help reduce emissions. During maintenance, it's important to regularly clean the fuel injectors and filters to avoid clogging that could affect performance. When transferring ownership or registering the car, some major cities like Beijing and Shanghai have restrictions on China V vehicles, such as not being allowed inside the inner ring roads. I recommend consulting the local vehicle management office before purchasing to avoid any hassles. Overall, the car is fuel-efficient, and as environmental standards continue to upgrade, it's good to stay updated on new regulations in the future.
As an environmentally-conscious young person, I appreciate that cars manufactured in 2018 typically meet the China 5 emission standards, which represent significant progress over the older China 4 standards, reducing pollution by around 20%. Checking the environmental status online is quick and easy – just one minute via Alipay's mini-program. Emissions directly impact air quality, so I make a point to reduce sudden acceleration and frequently use eco-mode while driving to ensure exhaust emissions stay within standards. Many new cars now comply with the stricter China 6 standards. Choosing a vehicle with higher emission standards can save you taxes and prove more economical in the long run. I recommend car owners regularly conduct exhaust emission tests to ensure compliance, avoiding potential fines or difficulties during vehicle transfers. This directly affects the clean air we breathe, so it's something we all need to take seriously.
I've been driving for over 20 years and understand emission standards. Vehicles produced in 2018 are mostly China V compliant. China VI standards were implemented in the second half of 2019 - you can check your vehicle's environmental label or registration certificate for details. Emissions affect daily vehicle use; China V vehicles need special attention to exhaust parameters during annual inspections, otherwise they may fail the test. When driving my China V vehicle on highways, I find the fuel consumption normal without major issues. However, be sure to verify the manufacturing date when buying used cars to avoid being misled. Overall, these vehicles remain practical, reliable, and compliant with regulations in most regions.
