When was China III implemented?
2 Answers
China III standard was implemented on July 1, 2007, and ended when China IV standard was implemented on July 1, 2010. Vehicles produced between 2007 and 2010 all met the China III standard. Below are the relevant introductions to China III and China IV: 1. China III emission standard: mainly refers to HC emission value below 0.2g/km, CO emission value below 2.3g/km, NOx emission value below 0.15g/km, with no PM requirement. 2. China IV emission standard: mainly refers to HC emission value below 0.1g/km, CO emission value below 1.0g/km, NOx emission value below 0.08g/km, with no PM requirement.
The nationwide implementation of the China III emission standards was on July 1, 2007. I remember it clearly because I had been driving an old car for years, and air pollution was severe, with black exhaust smoke being common. Once the new standards were introduced, automakers started producing models equipped with advanced catalytic converters, reducing urban smog, and driving a new car felt much fresher. This policy drove advancements in automotive technology, such as reducing nitrogen oxide emissions. Extending to daily life, car owners had to pay attention to maintaining their catalytic converters, or they would face issues during annual inspections. Nowadays, the China VI standards are much stricter, but the China III era was a significant change that impacted the used car market, causing prices of older vehicles to plummet. When choosing a new car, I always check the emission records first to ensure it's environmentally friendly and durable.
