Dongfeng Cummins: To manufacture more to R & D

“Dongfeng Cummins Engine Co., Ltd. has gradually realized the simultaneous development with Cummins Inc. in the United States through product introduction and continuous independent innovation. The quality of its products has been continuously improved, its market share has been gradually expanded, and its overall strength has been continuously enhanced.” Dongfeng Motor Co., Ltd. Technology Zhang Tao, director of the department, told reporters that in recent years, the company’s products have actively developed the external market while supplying Dongfeng commercial vehicles. Anhui Hualing, Zhengzhou Yutong, Xiamen Jinlong, Liugong Machinery and other domestic automobile and construction machinery manufacturers have been selected. Dongfeng Cummins Engine. The economical, dynamic, reliability and durability of products are widely praised by users at home and abroad.

The introduction of technology has appeared "acclimatized"

Dongfeng Cummins is a modern diesel engine manufacturing company jointly owned by Dongfeng Motor Co., Ltd. and Cummins Inc., each with a 50% share. As a national high-tech enterprise, the company mainly produces Cummins B, C, L series mechanical engines and ISDe, ISLe, ISZ series fully electronically controlled engines and B series natural gas engines. The engine displacement is 3.9L, 4.5L, 5.9L, 6.7L, 8.3L, 8.9L, 13L and so on. The company's products can meet the requirements of State II, State III, and State IV emission regulations, and are widely used in light, medium, and heavy-duty trucks, medium-to-high-level intercity buses, large and medium-sized buses, construction machinery, and generator sets.

Dongfeng Cummins' technology is directly introduced by Cummins of the United States. Faced with a vast and uneven market in China, the Cummins engine has appeared to be “satisfied with soil and water”. The original copy or innovation, is a topic placed in front of the majority of technical personnel, Dongfeng Cummins resolutely chose this road of innovation.

Taking innovation as the concept of enterprise development

Based on the introduction, digestion, and absorption, Dongfeng Cummins has taken "innovation, enterprising, and collaboration" as its core value and accelerated the pace of independent innovation. At the same time, the company vigorously promotes Six Sigma management to achieve product innovation and quality improvement.

Zhang Tao told reporters that after the introduction of the B-Series engine into the Chinese Market, Dongfeng Cummins has made a series of localization improvements, including product performance enhancements, emission upgrades, and parts localization. Since entering the year 2000, the company has successively improved the fuel economy of the imported C-series engines on the basis of the domestic fuel system, and developed the L series 4-valve heavy-duty diesel engine with independent intellectual property rights. Market evaluation. In addition, a self-developed high-velocity heavy-duty diesel engine that meets the National IV emission standard will also be launched in 2009.

In addition to product innovation, Dongfeng Cummins has continued to innovate in management and successively passed ISO/TS16949, ISO/14001, OHSAS/18001 quality, environmental, and safety system certifications.

The East Asian Engine R&D Center jointly established by Dongfeng Cummins and Cummins in Wuhan is the world’s second largest R&D center established outside of the United States. The research and development tasks undertaken by Cummins are not only for the Chinese market but also for the developed markets. At this point, Dongfeng Cummins will gradually realize the transformation from simple production and sales to R&D, production and sales. And it is gradually occupying an important position in Cummins' global industrial chain.

Develop UPB Engine Independently of China's National Conditions

The UPB series electronically controlled single pump engine is a product independently developed by Dongfeng Cummins in combination with China's national conditions. After small batch production in 2008, the market responded well.

The UPB engine was developed based on the B-Series engine that meets the National II emission standard. It maintains the characteristics of advanced product performance and strong reliability, uses domestically-made electronically controlled monomer pumps for performance matching, and meets the requirements of the National III emission standards. The engine's power is 125~160 kilowatts. It is mainly used in heavy-duty trucks, passenger cars and construction machinery. Its biggest feature is that the engine's fuel system can be upgraded from the original mechanical type to full electronic control, and it can still be used with the original production line. Mixed-flow production achieves lower manufacturing costs while taking into account the versatility of spare parts. The project expanded the product range of Dongfeng Cummins and extended the life cycle of 6B series engines.

Zhang Tao introduced to reporters that the innovation of UPB products is to use the “domestic electronically controlled monomer pump system + two-valve cylinder head” technology to make engine emissions meet the national III standard. In the initial stage of product development, Dongfeng Cummins had in-depth study of customer needs, and after using advanced computer-assisted systems for product performance analysis, it was considered that this technical route was feasible. If other technical routes were chosen, the product development cycle and the whole machine The cost can not meet the market requirements. This plan was once questioned by foreign experts, but the development plan was implemented under the insistence of Chinese personnel. During the product development process, Dongfeng Cummins adopted ESW (Standardization Workflow) and DVP&R (Design Validation Plan) for product performance and quality to ensure that the product meets the requirements. This approach is not the same as the company's previous practice. Previously, more experience was required. ESW and DVP&R required the development of project progress through cross-departmental review at the beginning of design. This approach greatly shortened the product Development cycle.

At present, UPB has obtained 4 utility model patents authorized by the state. At the same time, it is also the first low-cost, world-class project that Dongfeng Cummins initiated and has been recognized by the Cummins headquarters in the United States.
