Say goodbye to the glory of the past--Recalling the history of the Dongfeng EQ6100 engine

In May 2013, the EQ6100 engine assembly line announced the suspension of production after the completion of the final engine assembly and will completely withdraw from the historical stage of commercial vehicles in China.

The EQ6100 engine is a peak of China's automotive engine and a milestone in the independent innovation of Dongfeng Motor and even the Chinese auto industry.

The glory of the EQ6100 is obvious to all. However, with the continuous development of the automotive industry, the suspension of the EQ6100 is a historical necessity.

Looking back at the history of the EQ6100 for more than 40 years, it is not difficult to find that the EQ6100 is a product that is full of fascination and does not fade due to the passage of time. It not only established the industry status of the Dongfeng Commercial Vehicle Engine Plant, but also ignited it. Dongfeng manages the spark of innovation and innovation, and condenses the great spirit of the Dongfeng people who are represented by the engine factory, striving for self-improvement, forging ahead, and reviving dilemmas!

This is a spirit worth passing on:

Self-improvement, dare to fight can win

The history of the development of an EQ6100 engine is also an entrepreneurial history and struggle history when the engine factory is irresponsible for the times.

In 1969, the first bonfire of Dongfeng Venture was ignited in Shizigouzigou. A group of aspiring young people, a deserted land, a dream of a powerful car-making country with a common passion, “Dongfeng Dream,” began to realize here. As the “heart” of the car, independent research and development and manufacturing of the engine started here.

“Despite the difficult conditions, we have the determination to 'knock it with your hands, use your gums, and build your engine'.” As the witness and witness to the growth of the EQ6100 engine, Zhang Zhiquan, former director of the engine plant, has worked hard for that period of time. But passionate memories are still fresh.

In March 1970, the first EQ6100 engine was tested and assembled in the factory temporarily rented in Sancha. Within 10 months, it successfully installed 10 engines. However, after more than one year of equipment installation, commissioning and trial production, product design issues and equipment quality problems, especially equipment problems and process problems with “disease” into the mountains have been exposed.

Speaking of the predicament at the time, Zhang Zhiquan could not help frowning: "But the solution is always more difficult than that." In order to solve the internal cleanliness of the engine compartment, everyone brainstormed and came up with some clever ideas: "Use copper pipe welding One iron brush, first magnetize the iron brush, and then extend it into the cylinder to suck iron scraps that are difficult to remove. If you do not suck twice at a time, Zhang Zhiquan said. These "earth" measures, although they were compelled by the shortage of materials at the time, resolved many urgent needs. As a result, many problems were broken.

With the R&D, production and development of the EQ6100 engine, the spirit of the engine manufacturer's self-improvement, determination, and courage to win can be achieved.

In the second half of 1993, the EQ6100 once again experienced a test of life and death: the automobile dieselization turmoil swept across China, and the production of gasoline vehicles drastically declined. The engine plant was forced to collapse by the fiercely competitive market because of its single product and weak competitiveness. EQ6100 Also due to the implementation of the National 0, State I emission standards, product production and sales reached a low point.

Faced with the EQ6100, which has devoted a lot of hard work to it, all employees in the factory adhere to their beliefs and inherit the spirit of the older generation of entrepreneurs. In 1994, they set off a climax of “second venture” in the whole factory. This "second startup" extended the life cycle of the EQ6100 and also laid a solid foundation for the future development of the engine plant.

This is a history worth writing:

“Going out and introducing” to develop independently in opening up

History has given Dongfeng Engine Factory a heavy responsibility. Born in a special period of time, EQ6100 has embraced the spring breeze of reform and opening up, and has made indelible contributions to Dongfeng Motor and even the Chinese auto industry in terms of production management, quality improvement, and technological innovation.

In November 1977, Dongfeng entered into a cooperation agreement with Ricardus UK. The main content is to evaluate the EQ6100 series engines. This is the first time that Dongfeng has introduced foreign technology since its construction. This cooperation has also made the Dongfeng Company, which is innovative and good at learning, become Since the reform and opening up, China's auto industry has been the first state-owned large-scale enterprise to introduce foreign technology.

Recalling the introduction of this technology, Rao Rulin, deputy director of the former Dongfeng Engineering Research Institute, said with a lot of emotions: “This cooperation has enhanced our R&D level on the one hand, and on the other hand has improved our testing level. In 1979, the EQ6100 engine passed 1000 Full-time full-load test at full hour speed.” With these technologies and experience, Dongfeng has achieved a rapid increase in the level of engine R&D and manufacturing, and subsequently participated in the development of three important engine standards for China – “Engine Test Standards for Automotive Engines” and “Automobile Engines. "Reliability Test Standards" and "Rules for Engine Steering Tests."

In the R&D and manufacturing process of EQ6100, the engine plant adhered to the combination of independent development and technology introduction and implemented the research and development ideas of “first-in-class development, first-in-a-industry integration, development of clean energy and environmental protection models, and serialization of various types of products”. On the one hand, engine manufacturers use “going out” methods to send personnel to the United States, Germany, Japan, and other countries to accept the learning and training of new technologies and concepts; on the other hand, through “bringing in” to Japanese companies, French companies, etc., carry out product technical improvement consultations, implement and implement total quality management in all aspects of production, and consider, from each person, every procedure, to every product, a comprehensive assurance system.

Since 1986, EQ6100 has been maintaining the level of domestic first-class products. In 1991, it was awarded the title of Quality Product of the Ministry of Mechanical and Electrical Industry. The engine plant assembly has reached the national excellent standard; in 1992, the output reached the highest peak in history with an annual output of 135,327 sets.

This is a treasure that should be treasured:

"Second Venture" EQ6100 Old Tree Blossoms

The history of the rings has entered the 1990s. The EQ6100, a product that has received favorable reviews from the market, has experienced continuous baptism of the market tide.

In the second half of 1993, the impact of the market and changes in market conditions, the engine plant has reached a crossroads of development. "There were only two roads before us. One was to let nature go and self disappeared. The other was to forge ahead and keep pace with the times to produce a high-level engine that meets the requirements of national laws and regulations and the needs of users." Peng Quanchun, the original director of the engine plant, recalled.

The cadres and employees of the engine plant took up the heavy responsibility with their strong willpower and the courage to catch up and chose the “second venture”. In the world, we explored a path of "market-oriented, formulating product development plans, building product development platforms, accelerating product structure adjustment, and improving the Dongfeng engine brand system."

To enable the EQ6100 this leading product to continue to adapt to market demands, the engine plant R&D department rejuvenated through the infusion of technologies such as computer ignition, electronically controlled air addition, and dual fuel. Due to its small power and limited range of use, the R&D department of the engine plant has reconstructed its EQ6105 series products and applied electronically controlled air-supply technology, computer-less ignition system and air-fuel ratio closed-loop control system to the EQ6100. , And redesigned and manufactured flywheels, signal disks and other components, adding an environmentally friendly engine to the EQ6100 series, and also compensated for the EQ6100 engine mismatch of 11 meters above the bus power shortage, expanding the product range of the engine.

In 2000, the application of exhaust gas recirculation and closed-loop electronic control and replenishment technology developed by the product R&D department of the plant on the EQ6100 eco-friendly engine enabled the EQ6100 engine to meet the requirements of national environmental protection regulations. The development of the CNG (natural gas) engine for the EQ6100 marine LPG engine and generator has created a precedent for the engine plant EQ6100 gasoline engine to reach other fields such as marine and agricultural use.

With the increasingly fierce competition in the engine market, engine technology is changing with each passing day, and the national emission standards have been continuously improved. The products of the 1970s process standards eventually withdrew from the stage of history.

For more than 40 years, the EQ6100 has completed nearly 2.5 million units in the total output of 3 million units produced in the engine plant. From glory to silence to rebirth and fade out, only the phoenix-like experience will make all the Lost and become wealth, make the EQ6100 a monument. The time for this classic product is not only a figure, but also a spiritual, an unforgettable history.
