Municipal authorities in Beijing have started soliciting public opinion about proposed new vehicle emission standards. Under the proposal, which covers both passenger and commercial vehicles, Beijing s Environmental Protection Bureau is hoping to cut vehicle emissions by 30-percent in the next 7-years.
Director of the bureau s vehicle management office, Li Kunsheng, says it s time to adopt the
world s strictest emissions standard in the city. "In the Beijing-Tianjin-Hebei region, fresh air is not enough. So we have to implement the most stringent emission standards in the world. Also, we need to give car makers around two years to produce new vehicles which adapt to the new emission standard."
Phase-6 of the emission standards will require passenger vehicles to pump out 40-percent less exhaust in 2-years time. Vehicles with larger motors, such as buses and industrial vehicles, are going to have to cut their emissions by 50-percent.
Currently, vehicles in Beijing need to meet the fifth phase emissions standard, which went into effect in 2013 and is equivalent to the Euro 5 emissions cap.
Li Kunsheng says other measures will be adopted to help reduce emissions. "We have decided to install particle trap devices for heavy diesel vehicles and other vehicles with big emissions. It s hopeful that their pollutants emissions can be reduced by 90 percent."
It s been announced that the new emission standard is expected to be implemented in December, 2017.
The bureau estimates that pollutants emitted by vehicles will be cut by 30 percent by 2022.
For LDVs, Beijing 6 standard adopted California LEV III’s ULEV 70 bin as the maximum emissions limits, 5 test cycles (FTP, cold temperature FTP, HWY, US06 and SC03), OBD II requirements as of the 2015 version, and a 200 thousand km durability requirement. And Beijing proposed a set of PEMS-based emissions limits for in-use conformity: not exceeding 1.2 times the FTP limits.
The HDV standards are more innovative! There are two sets of requirements in parallel: Euro VI equivalent engine-based emissions limits; and a set of full-vehicle based emissions limits. The full-vehicle emissions standard includes chassis dynamometer testing method and emissions limits as 1.2 times the Euro VI WHTC limits. Beijing also adopted CARB s newly released defeat device screening test requirements using PEMS testing. In addition, Beijing requires remote OBD testing as part of the in-use conformity requirements.
