In September 2014, Weichai formally released the “Power 3D †power product WP3 . Within a short period of one year, the sales volume has exceeded 10,000 units. With an amazing growth rate, it is absolutely impermissible for Sharp Power. Phi-jian's deep implied meaning and good hopes made a perfect footnote. How does this “explosive product†come from? What kind of development team is behind WP3? What excellent genes have they given to WP3? An excellent "expert" team WP3 is a classic of Weichai's smart power platform and a typical case of Weichai's collaborative development of the resources of the “Five Countries and Ten Regions†R&D center. The design of the program is completed in Hangzhou; prototype manufacturing and application are completed in Yangzhou; vehicle matching is Shanghai completed; performance optimization completed in Weifang. More than 120 engineers participated in the WP3 project, including more than 40 key engineers. It is a very young and dynamic "expert" team. In the team, most engineers have more than 5 years of experience in engine technology research and development, and some have more than 10 years of experience in R&D. This has played an important role in bringing good teams and improving the research and development level of young engineers. A series of extremely harsh development processes Weichai products have consistently established industries with “high reliabilityâ€. According to the WP3 development team, as the "new cutting edge teacher" of Weichai's lightweight power, the WP3 series products are designed and developed in full accordance with the development philosophy and flow of Weichai's heavy-duty engine. Nearly one thousand R&D standards under this process are all higher than national standards, industry standards and user requirements, covering all aspects of product development. The biggest advantage of developing light machines in the heavy machine process is that the product has particularly obvious advantages in terms of reliability. In popular terms, it is: durable and economical. According to Han Jingfeng, one of the leaders of the WP3 project, in terms of reliability, WP3 has fully absorbed Weichai's decades of heavy engine development experience and data, and conducted rigorous endurance tests on complete machines and key components, causing potential problems. Fully exposed to the test phase, and continue to solve the perfect, in order to ensure high reliability of the product. “This is the biggest advantage of Weichai to other companies. General enterprise development is light, and it does not attach importance to endurance testing. As long as the product is manufactured and installed on the car, it can be run on the line. Therefore, after the delivery of customers, various problems erupted. †A unique "exclusive design" WP3 is not only highly reliable, but its other advantages are equally impressive - NVH performance is excellent. Weichai NVH engineer Tian Xinwei and several colleagues participated in the WP3 NVH performance optimization process. He said that relative to competitive products, the WP3 has obvious advantages both in terms of the engine unit and the NVH performance of the matched vehicle, and has been widely praised by the OEM and customers. In addition, WP3 has an "exclusive design" that fully guarantees its comfort. Han Jingfeng’s engineer said that WP3 is the first light commercial diesel engine to use a “secondary balancing mechanismâ€. What is the magical effect of the secondary balance mechanism? The engineer has made a professional interpretation. The secondary balancing mechanism in the WP3 engine adopts the principle of balance shaft to solve the engine vibration problem. Balance shaft, a shaft equipped with an eccentric weight and rotating synchronously with the crankshaft, uses the reverse vibration force generated by the eccentric weight, so that the engine achieves a good balance effect and reduces the engine vibration amplitude. The structure of the balance shaft is more complicated and costly, and it is more commonly used in large-displacement vehicles. The WP3 engine is capable of adopting a secondary balancing mechanism, which shows that the development team has given WP3 high hopes and hopes that WP3 can bring more value driving experience to customers. A never-ending "concentration" At present, the WP3 market is a success story, and engineers are very proud and pleased to see that their own “batch†products are favored by customers. However, they also frankly stated that when the project development was not completed, only a phased victory was achieved at present. In the later stage, according to the needs of customers, “Customized Edition†WP3 was launched according to the different working conditions in different market segments, such as the bus version and plateau. Versions, cold editions, city logistics editions, rural transportation editions, etc., maximize the potential of products. Dual Interface Smart Card is more flexible and convenient than other smart card, with its better support for multiple applications. Yuanmingjie Technology has the complicated producing processes (including Milling And Pulling-out, embedding, card punching, packaging and sorting), which can be chosen by our customers.
