Listening to the Wind for 50 Years: Retrospect of Dongfeng EQ6100 Engine Development (I)

As Dongfeng 's first self-developed engine, the EQ6100 plays a decisive role in the development of Dongfeng and even the development of the Chinese automobile industry for 47 years. On the afternoon of May 28, 2013, the EQ6100 engine was officially shut down, but the engine's spirit accumulated over 40 years did not stop there. With the continuous upgrading of engine technology, the suspension of production of the EQ6100 is a historical necessity. However, this engine witnessed the difficult development of Dongfeng entrepreneurship and condensed Dongfeng's history and culture for 47 years. The Dongfeng people showed a panoramic view in this engine with the spirit of hard struggle, independent innovation and openness and inclusion.

A group of aspiring young people, a deserted land, and the dream of making a car-building country together ... "Dong Feng Meng" rises from here. As the heart of the car, the engine's independent R & D and manufacturing work is expected. “In spite of the difficult conditions, we have the determination to 'knock your hand and use your gums to build the engine'.” As the witness and witness to the development of EQ6100, the original engine plant manager, Zhang Zhiquan, has been struggling for that period of time. The passionate memories of the years are still fresh. In March 1970, the first EQ6100 engine was trial-assembled in the factory temporarily rented in Sancha, and 10 engines were tested and installed here in half a year. However, after more than one year of equipment installation, commissioning and trial production, product design issues and equipment quality problems, especially equipment problems, process problems, and tooling problems with “diseases” have been exposed. In the face of difficulties, the older generation of engine manufacturers never cowered, and various production lines of various issues were gradually opened up.

With the development, production, and development of the EQ6100 engine, the spirit of the Dongfeng engine planter has also been molded: self-improvement, determination, courage and success.

In November 1977, Dongfeng signed a cooperation agreement with Ricardus in the UK. The main content is to evaluate EQ6100 and EQ6105 and to modify the design of EQ6105. This is the first foreign technology introduced since Dongfeng built the plant. The east wind that has been innovative and good at learning has become the first large-scale state-owned enterprise in China's auto industry that has introduced foreign technology since the reform and opening up. Recalling the introduction of this technology, Rao Rulin, an older generation of engine plant technicians, has a lot of emotion. “This cooperation has enhanced our R&D level on the one hand and our testing level on the other. In 1979, the EQ6100 engine passed a full-load test at full speed of 1 000 hours.” With this accumulation of technology and experience, Dongfeng is The level of engine R&D and manufacturing has been rapidly increased, and it has subsequently participated in the formulation of three important engine standards for China – “Engine Test Standards for Automotive Engines”, “Reliability Test Standards for Engines for Automobiles” and “Rules for Engine Steering Tests”. Despite being in the mountains of northwestern Hubei Province, Dongfeng’s entrepreneurs placed their eyes on the entire world, facing the gap with the world’s advanced level, not pessimistically, and not conceited, and working hard to learn advanced technologies in the world with an open mind. This is the result of Dongfeng’s later joint venture and cooperation. A good cultural foundation.

With the changes of history, this spirit has become increasingly brilliance in the continuous transmission. In the second half of 1993, the EQ6100 experienced another test of life and death after experiencing the initial stages of the venture: The automobile dieselization storm swept across China, and the production of gasoline vehicles drastically declined. It once made Dongfeng a reputation for excellence in Kyushu. The contribution of the engine plant, due to a single product, weak competitiveness, mercilessly forced by the fierce competition in the market to the edge of disintegration, EQ6100 due to the implementation of the National I emission standards, product production and sales into the lowest since the construction.

More than 5,000 workers faced the engine factory that had fought for it and the EQ6100 that had been devoted to it. They adhered to their beliefs and passed on to the older generation of entrepreneurial spirit. In 1994, they set off a second venture in the whole factory. The climax. With hardships to forge ahead and conquering the city, depending on difficulties as an opportunity to dare to win, this “second venture” prolongs the life cycle of the EQ6100, and it also has a solid foundation for the future development of the engine plant.
