What is the maximum displacement allowed under China VI emission standards?
2 Answers
The maximum displacement allowed under China VI standards is 1.5T. Below is relevant information about China VI standards: 1. Implementation regions: The "Three-Year Action Plan for Winning the Blue Sky Defense War" stipulates that key regions, the Pearl River Delta region, and the Chengdu-Chongqing region will implement China VI emission standards ahead of schedule. 2. Implementation timeline: The China VI emission standard will be implemented in two phases - "China VI A" and "China VI B", with corresponding effective dates of July 1, 2020 and July 1, 2023 respectively. China VI A can be regarded as a transitional phase from China V to China VI. Some provinces and cities will implement China VI emission standards earlier, with specific timelines varying by region.
In fact, China's National VI emission standard does not directly specify a maximum engine displacement limit for vehicles. Its primary focus is on regulating pollutant emission levels. Regardless of engine size, as long as the exhaust emissions of nitrogen oxides, particulate matter, and other pollutants meet the standards, it's acceptable. I often see some friends mistakenly believe that engines over 2.0L displacement can't meet National VI standards, which is completely incorrect. In reality, even new 3.0T large-displacement vehicles in dealerships can still be registered - the key lies in the automaker's emission control technology. For example, many luxury cars equipped with efficient particulate filters and dual injection systems can easily meet National VI-b standards even with V6 engines. Of course, larger displacements present greater technical challenges, which is why small-displacement turbocharged engines are becoming increasingly popular.
