At the end of 2019, according to the "Shandong Provincial Science and Technology Award Measures", it was reviewed by the Shandong Provincial Science and Technology Award Review Committee, reviewed by the Provincial Science and Technology Award Committee and reviewed by the Provincial Science and Technology Department, approved by the provincial government, and approved by Weichai Power Co., Ltd., Shandong University , The project "Development and Industrialization of Key Technologies for High Efficiency Aftertreatment System for Diesel Engines" jointly declared by Wuxi Weifu Environmental Catalyst Co., Ltd. and Weichai Power Air Purification Technology Co., Ltd. won the first prize of Shandong Science and Technology Progress Award.

Wuxi Weifu Environmental Protection Catalyst Co., Ltd. is responsible for the research of post-treatment catalysts, and has developed a DOC coating technology with outstanding low-temperature activity and excellent NO oxidizing ability. Through the Pt/Pd bimetal ratio partition coating, precious metal reduction has been achieved; optimization The CDPF partition controllable coating process has been developed, and the batch production of CDPF with low back pressure and high collection efficiency has been realized; the rapid molecular sieve material preparation and efficient copper loading technology have been developed, and the catalyst's low-temperature activity and ammonia storage performance are better than the international counterparts. The diesel engine matched with the aftertreatment products developed by the project has passed the Euro VI emission certification and the China VIB emission certification.
