Shandong Power Heavy Industries Weichai Group developed its own intellectual property rights Lanqing Power – WP5, WP7 excavator supporting engine was successfully developed, after rigorous testing and will be officially launched in the Chinese market in the near future, which will change the foreign engine on China's excavator supporting market Monopoly situation.
According to Zhu Qing, general manager of Weichai Power Engineering Machinery Sales Co., Ltd., Weichai Group launched the research and development of WP5 and WP7 engines at the end of 2005 and cooperated with internationally renowned companies. At the end of 2008, the prototypes were introduced, and the total experimental time has reached more than 30,000. Hours, the total vehicle experiment totaled 1.2 million km, much higher than European standards.
According to reports, these two engines have the advantages of high reliability, low fuel consumption, light weight, and low noise. The product adopts a high-intensity connected cylinder block and a high-strength crankshaft. The gantry reliability and endurance tests have been accumulated for over 8,000 hours, and the entire diesel engine has an overall operating life of over 2 million km. The new generation of Bosch high-pressure common-rail pumps has been used to create the same row of oil. The new model of the model, rated at 290g/kw. h, comprehensive fuel consumption 206g/kw. h; The use of rear-mounted gear system, the overall quality of only 620kg, the lightest model for the same displacement, the laboratory 1m noise is only 95db.
In addition, during the research and development stage of WP5 and WP7, Weichai Group has made certain improvements in the use conditions of excavators, and has conducted adaptive development in light of the fact that China's oil products are not high, the territory is vast, and operating conditions are greatly different. The engine was individually designed according to different environments.
Weichai Group is China's largest auto parts enterprise group. Its engine's supporting rate for domestic loaders is as high as 80%, and the matching rate of cranes also reaches 40%. Among them, the WD10 loader engine has been the first of its kind in the global loader.
With the successful development of WP5 and WP7 excavator engines, Weichai Power has the ability to cover a full range of engines ranging from small excavators to large and medium excavators. At present, China has become the world's largest consumer market for excavators and the manufacturing center for excavators in the world. However, foreign brands accounted for the main market, and internationally renowned excavator brands have entered the Chinese market in full, and their market share once exceeded 90%.
