Xing Min, executive vice chairman and secretary-general of the China Internal Combustion Engine Association, said that this is a miracle, a legend, and a fact. This fact shows that our own intellectual property diesel engine can achieve great success. We are also pleasantly surprised to see that Xichai Engine has a complete industrial chain. Not only is Aowei proud, but also proud of FAW. Our industry is also proud. Where is pride? Because as a key component of the vehicle, the engine represents a certain level of technology. The performance of Xichai also just proves that the prerequisite for the development of the internal combustion engine industry is that parts and components must be strong and parts and components must be strong.

FAW Xichai is an important part of the strategic chain of commercial vehicles of the FAW Group. It has invested huge amounts of money and has brought amazing results. Xichai Power is becoming the national leading diesel engine power brand to serve the world. Wang Lizhi, general manager assistant of FAW Group Corporation, said: FAW is the eldest son of the Republic. During the 12th Five-Year Plan period, FAW established the goal of striving for the first-half market share of medium- and heavy-duty trucks, and also for the international market, to create an internationally renowned brand. The powertrain is undoubtedly the core element of the competitiveness of the vehicle, how good the engine is, and how reliable the entire vehicle is. The liberation of FAW has always adhered to the development ideas of independent development and open cooperation. As a production plant for the liberation of heavy-duty diesel engines, Xichai has invested more than 2 billion yuan in the construction of a new base, and the Group’s investment in the Huishan base has exceeded a total of 4 billion yuan. In the eleven years after the Aowei engine went offline, it produced 600,000 units. The technology of the engine has been upgraded from the original 8-liter 9-liter machine. Now it has reached the 13-liter 11 machine. The product layout is full of series and continues to advance. This is the post-liberation period. Bigger and stronger also laid a very good foundation. The 200,000 kilometers of overhauled engine 600,000 units off the assembly line mark the level of our own brand engine to the world's leading level, and at the same time form a good foundation for China's own brand to build a world-renowned brand.

The goal of FAW Xichai's products is to keep up with the progress of the national diesel engine regulations, receive the lead and become an example. FAW provides continuous technology research and development support for Xichai, builds a first-class, systematic manufacturing management system, guarantees high-quality products with high-standard R&D, and high-standard manufacturing, and high-quality products support the implementation of national environmental protection policy standards. Xu Xianzhi, general manager and secretary of the Party Committee of FAW Jiefang Co., Ltd., said: Aowei's engine is not overhauled for 2 million kilometers. From the matching of its entire vehicle-liberation product, the J6 plant and the J5 plant are equipped with Aowei engines. J5 won the second prize for national scientific progress in 2007, and J6 won the first prize for national scientific progress in 2010. Both products are high quality and high quality products. Having visited the Aowei production line, we know that it is difficult for such an advanced production line to make unqualified products. The robots are automatically tested and these standardized productions make each of Xichai's products a quality product. For many years, Xichai regards its quality as its life, and its life only once is the knowledge of every Xichai people about quality. The reliability engineering and meticulous engineering that are being vigorously promoted have further promoted the development of Xichai products.

In terms of implementation of the National IV emission standards, although the current vehicle urea oil products and other supporting systems are still not perfect, all 350 cities in the country are gradually implementing the national IV implementation according to the time. According to the requirements of the Ministry of Industry and Information Technology, January 1st, 2015 must be comprehensive. In terms of liberation, China’s implementation of the Fourth National Plan is the most adequate. In the mid- and heavy-duty truck industry, data from January to May show that the largest proportion of the four products in the liberation country is sold. We strictly implement the fourth national emission policy in the implementation country. Four regions sell real four products.

For the marketing worker, Yuxin believes that "the quality of the product is the final say for the customer market." How will the quality of word-of-mouth bring strength to the liberation of product marketing? Jing Qingchun, general manager of FAW Jiefang Sales Co., Ltd., said: The liberation of Aowei series products has been continuing to go high since the beginning of 2013, and even in all the provinces across the country there have been hot sales. From January to May 2014, it achieved a year-on-year growth of 22%, of which, the sales of the 11-litre Aowei engines in 2014 increased by 86% year-on-year. The Aowei engines provided a strong boost and support for the growth of the entire vehicle fleet. Aowei has played a very important role in liberation of the market breakthrough for short-dump trucks. For Liberation, our short version of the product is a dump truck. In 2014, we made adjustments in our product strategy and accelerated the market introduction of J6 Aowei 11 liters of dumping products. This achieved very good results in the country. Especially in the western market. In 2014, the dumping products in the Guizhou market increased by 22% year-on-year, and the dumping products in the Yunnan market increased by 136%. The final result was very encouraging.

From the perspective of market performance and user reputation, Aowei's products perform well, and no major overhaul of 2 million kilometers is the best witness. In the 11 years since its launch, Aowei series products have accumulated a very good reputation in the market, and they are in a leading position in the industry in terms of leading technology, reliable fuel economy, and low-carbon environmental protection.

The Gold Cup Silver Cup is not as good as the user's word of mouth. The Xinjiang Hetian Shuntong Transport Company has used it for nearly ten years to liberate Aowei Trucks and Aowei Diesel Engines. The general manager Yang Jiangquan said: The correct choice and meticulous maintenance are our fleet volume reaching 200 Thousand kilometers without major repairs. Years of experience have shown that the quality of Xichai Aowei machine is indeed reliable. Let us use the confidence that Xichai factory is always for the sake of users. Aowei Liberation Vehicle is our golden collocation and correct choice.

The development history of Xichai for 71 years and the efforts of several generations of people. For Xichai people and Xichai users, Xichai has become more than just a company, but can be dependent on emotions, sustenance, sharing honors. Ms. Xu Xuefen, Secretary of the Party Committee of Wuxi Diesel Engine Plant of FAW Group, said: Xichai carries such a dream of national high-end brands. Xichai also embraces the dream of a century-long enterprise. This is the spiritual power of Xichai people. Xichai is rooted in technical research, meticulous in product manufacturing, and we have full confidence in product management. In terms of brand management, Xichai has completed the brand's architecture and completed the top-level design, including Aowei, Hengwei, and Conway. Product sub-brands, to enhance brand recognition for different levels of different purposes, Aowei is one of the leading product brands.

The most important aspects of brand building are two aspects: external, building brand loyalty, reputation, and recognition, allowing more users to share the value of growth and quality; internal and lean management to ensure product quality. , to ensure that Ao Wei engine technology is not only a five-year lead, but also leading in fifteen years. The 71-year history of Xichai has earned a good reputation in the management of the industry, creating unique experience in lean management and ensuring that the products are leading in the industry.
