Founded in 1943, with the banner of “National Brand, High-end Power”, it has now entered the 75th year of Xichai. After the baptism of time and the tempered years, it has proved to be a benchmark for the Chinese internal combustion engine industry. Thanks to the national “One Belt and One Road” initiative, Xichai IC Engines has been sold to more than 40 countries and regions including Europe, the United States, the Middle East, and South Africa. It has become a highly sought after object in overseas countries and has stood up to the backbone of China’s own brands. All this is precisely due to Xichai's constant innovation in superb technology and its unremitting pursuit of superior quality.

Adhere to the technical lead, make their own brand more ethos

In the 21st century, global development has become a deep family of deep communication and integration. In order to gain a firm foothold in this big family, excellent technical strength is essential. Looking back at the history of the Xichai plant, the 75-year history, after four ventures, the development and utilization of diesel engine technology has always been an important part of Xichai's R&D work.

When it comes to Xichai's technical strength, the first thing that comes to mind is the post-processing technology. At present, Xiceq's post-processing technologies mainly include SCR technology and DPF technology.

It is known that the main components of the exhaust gas include hydrocarbons (HC), particulate matter (PM), nitrogen oxides (NOx), and the like. SCR, also known as selective catalytic reduction technology, is a treatment process for nitrogen oxides (NOx) in exhaust gas of diesel vehicles. Under the action of the catalyst, ammonia or urea is injected into the reducing agent to reduce the NOx in the exhaust gas to N2. And H2O.

In 2004, Xichai began to adopt optimized combustion plus SCR selective catalytic reduction technology and EGR plus POC particle oxidation catalysis technology. By 2012, it became the first company to implement two post-processing technology routes in the industry. Among them, the development of the optimized combustion plus SCR technology model began in June 2010 and will basically cover the coverage of major platform models in February 2011. Xichai targets the different displacements of the engine and the complete vehicle. According to the performance of the after-processor and the layout of the vehicle, the two types of post-processors, barrel-type and box-type, are designed and the barrel-type post-processing is refined into the upper right. Outlet, left and right out of the two intake methods, easy to install the vehicle layout. By the end of 2011, Xichai has completed the development of the SCR technology four-engine and post-processing system for each platform model, completed the SCR urea thawing test and plateau, high temperature and alpine tests, and completed the internal flow field of the postprocessor through CFD calculations. The analysis of the uniformity and uniformity of the structure of the post-processor has laid the foundation for Xican's in-depth study of SCR technology.

Xichai is actively working on DPF's technology reserves and product development

The DPF is a technology that was only used in the Euro six stage. However, with experience gained in the engine industry for more than 70 years, Xichai has already had an insight into the opportunities. Before the country’s five timetable was formally introduced, it was at the DFL. On the basis of mature technology, the company will actively start the technology reserve and product R&D of the State V diesel engine based on DPF. In the fifth stage of the country, when most manufacturers in the industry adopted a single SCR technology route, Xichai was the first to adopt the DPF technology route on light engines. In April 2017, the first domestic independent DPF diesel engine was launched at the Xichai DPF media communication conference and product promotion conference, which further enhanced the influence of Xichai Engine in promoting the green power brand in the light truck market.

It is reported that the DPF discharge post-processing technology is the most effective PM treatment technology at present, and the efficiency can reach more than 95%. Under certain conditions, it can achieve active regeneration, oxidize carbon particles, complete green upgrade, and fully comply with the national regulations and special regulations. The strict requirements of the Beijing Five regulations. The Xichai engine has now obtained 42 national invention patents, representing the highest level of environmental protection of domestic diesel engines.

Adhere to quality win, so that their own brand is more emboldened

Quality is the root of the company's survival. High-quality products are the magic weapon to fight all risks. Winning quality is the strategy that Xichai has always adhered to. It is the quality concept that Xichai always adheres to with responsibility for quality and responsibility for quality.

In Xichai, high-quality achievements are not controlled in a single production process, but run through every link. Through joint efforts to enhance product applicability, users' requirements are met to the greatest extent.

The first is to pay close attention to the quality of the purchased parts and ensure that “no bad flow” is achieved. In terms of supplier selection, a strict supplier selection, evaluation, and monitoring management process has been established. It must be a domestic first-class, internationally advanced supplier that has passed ISO/TS16949 quality certification. Secondly, we must pay close attention to the quality of self-made parts, ensure that “bad outflows do not occur”, strictly control key processes, strengthen prevention, and optimize inspections. The third is to pay close attention to the adjustment of quality. Strengthen quality management, implement quality guarantees, clarify the quality requirements for self-checking and mutual inspection, do not accept, manufacture, and deliver defects; develop “post zero defect” activities and implement quality requirements decomposition in each position. Ensure zero defects in the process and the quality of the entire machine is controlled. In order to ensure that each engine to the user's hands, are fine.

In the construction of the quality management system, Xichai's overall approach to quality work with “bearer responsibility for quality” has undergone a process from solid foundation to standard operation, from perfect process to performance-oriented development process, and has been constructed to emphasize innovative ideas and characteristics of Xichai. Focusing on the excellent performance management system that focuses on full participation and continuous improvement, we constantly strengthen employees' awareness of quality and further improve product and work quality.

Recently, Lu Xiaobin, director of the Information Analysis Center of Renmin University of China, pointed out that the development of China's own brands has become the national will.

As the representatives of China's "national core" autonomous power brand, Xichai has already fully prepared for the development of overseas markets. Technology maintains industry leadership, quality wins more trust from users, and independent brands are becoming the source of Xichai’s entry into overseas markets. We believe that in the near future, Xichai’s “high-end power” will certainly rank among the best in the world, making China a strong automobile company. Assist on the road for assisting the attack, to contribute to the rise of China's own brand Nuggets overseas market!
