The National Six Standard is currently the most stringent emission standard in the world. After the official standard was released, Weichai first jointed the testing organization with the environmental protection authorities to conduct technical docking, determine the certification test plan, and carry out the national six certification work. Under the supervision of the environmental protection department, on October 4, 2018, Weichai WP4.6N completed all the test items for the rig and the whole vehicle, and successfully obtained the national six b emission certification report for the heavy diesel engine. According to Xiaobian, the engine must be certified by the environmental protection authority and must complete the following processes: Product parameter filing → product type test → obtain test report and upload environmental protection system → enterprise to declare environmental information → obtain environmental information disclosure form. Only when the environmental information is disclosed, the National Six certification will truly complete the official certification. Weichai successfully obtained the national six b certification of heavy-duty diesel engines, which is not only the result of the research and development of Weichai, but also the mission and determination of Weichai to win the blue sky defense war.
