In the commemoration of the 50th anniversary of the development of the Chinese auto industry, the Chinese auto industry has summarized a variety of models that have influenced the development of the Chinese auto industry in the past 50 years. In the sequence of heavy trucks, Steyr was ranked among them.
Steyr, a beautiful small town in Austria, is both a European research and development base for diesel engines and a source of radiation for the leading trends and advanced concepts of the international combustion engine industry. Nowadays, in the small town where many European companies' R&D institutions are clustered, the presence of the Oriental companies has emerged—the R&D center established by China Weichai Power Co., Ltd. and AVL. It is here that Weichai people have nurtured "Lan-Qing WP10/12" - China's first 10-litre, 12-litre high-power Euro III engine with completely independent intellectual property rights.
Is "Blue Engine" a continuation of Steyr? Tan Xuguang, chairman of Weichai Power Co., Ltd., said that it is a brand-new key technology and independent brand with independent intellectual property rights. It is not a transformation based on the previous Steyr series.
Does "Lan Qing" have nothing to do with Steyr? This "proud" belonging to Weichai was jointly developed by Weichai and AVL. The development of the Weichai high-speed machine has also started from the introduction of Steyr.
Once darling
In the 1980s, in order to solve the problem of the Chinese auto industry's lack of heavy-duty vehicle production capacity, the state set up a heavy-duty automobile industry associate company and introduced the Austrian Steyr 91 series models together with China National Automobile Import and Export Corporation. Austrian side not only provides Steyr 91 series vehicles, but also provides WD series engine products, processes, standards and corporate management and other aspects of technology. In this project, Weichai was assigned to the production of engines.
In 1989, the Steyr engine produced by Weifang Diesel Engine Factory passed the acceptance of the national project, and the designed annual output was 10,000 units, and it began to support the entire vehicle. Since then, the Steyr engine has undergone more than a hundred localization adaptation improvements.
However, since China National Heavy Duty Truck's vehicle introduction project did not pass the national inspection and acceptance until 1993, and the investment has exceeded the original budget of nearly RMB 1 billion, a heavy financial burden and unfavorable market conditions have put the production of CNHTC into a dilemma. Only one engine plant, such as Weichai, which is supported by more than a thousand vehicles each year, is waiting to be fed.
Poor is trying to change
In 1998, Tan Xuguang became the director of the Weifang Diesel Engine Factory and opened the prelude to Weichai's reform. "Let the Steyr originally used for heavy trucks to support construction machinery."
Compared with the hard-to-start heavy-duty truck market, the market demand for construction machinery, especially high-power and heavy-load construction machinery, is rapidly heating up. The Steyr engine precisely fills this gap.
The reserve coefficient of torque for construction machinery requires up to 30%, while the vehicle only requires about 15%, which is a big gap; construction machinery is often used under non-road conditions, with large dust, large load changes, large changes in ambient temperature, and high work surface Unevenness, these all put forward the stringent requirements for the reliability of the diesel engine.
The engineers and technicians began to meet the specific needs of the construction machinery one by one from the aspects of Steyr's design improvements, parts and components, and overall performance enhancements. Within a few months, Steyr engines for the construction machinery industry were developed. Nearly 100 species. Steyr, with its advantages of sufficient power, low fuel consumption, low noise, and good reliability, has won the favor of users and soon became the dominant model of domestic construction machinery.
Rebirth changes
From the development of Euro I to Euro II, Weichai basically adopted the combustion performance to draw lessons from Steyr and its mechanical performance was based on my principle of research and development. From 2003 to 2004, Weichai high-speed machine made innovation on fuel consumption reduction on the basis of Euro II, and re-independently developed its combustion performance. At this point, from the introduction to digestion and absorption to innovation, Weichai spent more than 10 years turning the Steyr engine that crossed the ocean into the “weed developmentâ€. The newly launched “Blue Engine†series is another attempt of independent innovation by Weichai. "Now, the Steyr brand has been sealed, and our current WD615 is completely autonomous in technology." Sun Jian, director of the Weichai High-speed Machine Design Office, told reporters.
