What is the emission standard for cars in 2018?
1 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.
