When Did China National V Trucks Start Appearing?

Since China only began implementing the National V emission standards in 2017, the majority of National V trucks were manufactured after 2017. Additional Information: National V Standards: The National V emission standards impose stricter limits on vehicle pollutants such as nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM). Each upgrade from National I to National IV reduced single-vehicle pollution by 30% to 50%. Differences: Compared to National IV standards, the new standards reduce nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Based on Shanghai's annual vehicle registration volume of approximately 350,000 units, it's estimated that newly added vehicles could reduce annual nitrogen oxide emissions by about 1,000 tons.
As a veteran truck driver with nearly 20 years of experience, I remember the official implementation of China V emission standards for trucks was on July 1, 2017. Around that year, the government introduced new regulations targeting diesel vehicle emissions to address air pollution issues. At that time, I was helping our fleet update vehicles, and dealers emphasized that all newly produced trucks must comply with China V requirements, including lower nitrogen oxide and particulate matter emissions. While the previous China IV standards allowed some older technologies, China V mandated the use of SCR catalysts and DPF traps, which slightly increased our costs. However, in the long run, it helps reduce smog and makes urban driving more environmentally friendly. I also recall many manufacturers launching China V-compliant models as early as late 2016 to facilitate a smooth transition. In summary, 2017 marked a crucial milestone that drove industry-wide upgrades.
