"All diesel four-cylinder diesel engine as a domestic large-scale R & D and manufacturing enterprises, future development must accelerate innovation, accumulation and precipitation manufacturing capacity, promote the expansion of the scale enterprises to change the quality of growth, improve social acceptance of their products , To enhance the company's ability to regenerate and develop, said Xie Li, Chairman of Anhui Quanchai Power Co., Ltd., at the annual sales meeting held recently.

Mastering core technologies and applying modern manufacturing technologies

Diesel engine emission standards are increasingly strict. In the fierce competition with foreign companies and joint ventures, the development of local companies will face more and more challenges and pressures. Compared with the National 2nd and naturally aspirated diesel engines, the supply of the 3rd and 4th national diesel engines The oil system has undergone essential changes, and the conversion of the oil supply system from mechanical control to electronic control has been realized. The main technical routes include electronically controlled high pressure common rail, electronically controlled monomer pump and electronically controlled VE pump, etc., and they have started to increase the use of diesel aftertreatment. technology.

In order to cooperate with the implementation of the National 3rd and 4th national standards, Quanchai successfully developed a full range of national 3 and 4 engines through the introduction, digestion, and absorption of electronically controlled VE pumps, electronically controlled monomer pumps, and high-pressure common rails. A number of technical patents have been implemented, and the product technology has been continuously upgraded. The product structure has been gradually developed toward high-power and high-end technologies.

"In the face of industry competition, Quanchai's implementation of quality growth will in no way be limited to the introduction, digestion, and absorption of diesel engine core technologies. Quanchai will master the diesel engine core technology and accumulate core competitiveness based on the implementation of the human resources strategy. The core technology can gain the initiative in the future market competition, said Chairman Xie Li.

In recent years, Quan Diesel not only focuses on the mastery of core technologies, but also carries out technological transformations around diesel engine assembly, commissioning, processing, casting, etc., introduces advanced diesel manufacturing equipment and processes, and enhances the company's manufacturing capabilities.

In 2012, Quanchai put into production the forklift and construction machinery diesel engine assembly line introduced intelligent robots such as connecting rod bolts, flywheel housing bolts and oil pan bolts, etc., and set up 15 online detection points such as bore diameter detection and crankshaft swing torque detection. Effectively record and track quality information. Compared with the traditional production line, the production line also features high flexibility, high automation and high reliability.

In June of this year, Quanzhou Diesel's newly-built Lost Mold Casting Project, compared with traditional sand casting, not only provided sufficient freedom for casting structural design, but also reduced the weight of castings, reduced manufacturing costs, and effectively improved product quality.

Xie Li said that in the future development, Quanchai will continue to accelerate the application of modern technology in the process of technological transformation, actively promote the construction of enterprise information and lean production, and continuously improve the management capabilities and level of the enterprise.

Adjusting Structure and Quality to Quality Growth

“The rapid development of Quanchai in recent years reflects the growing ability of companies to adapt to market changes, adapt to national policies, and adapt to their long-term development strategies,” said Pan Zhongde, general manager of Quanchai.

Quanchai has completed the technical reserves, production capacity reserves, and future development plans for the full range of products from the country two to the national four, and can achieve long-term cooperation and development with various vehicle manufacturers.

In the first half of this year, the total diesel engine was reduced from 69% in the same period last year to 66% this year; the number of agricultural-type engines increased from 10% last year to 16% this year. In addition, Quanchai introduced the 4F series diesel engine for the first time in China Card, marking a new breakthrough in the structural adjustment of Quanchai's products.

Wang Zhiyi, deputy general manager of Quanchai, introduced that the 4F series engines were independently designed by Quanchai and provided consultations with AVL, combining domestic practice with the integration of advanced international design concepts. The overall performance of this engine is better than that of similar domestic products. Currently, it has participated in the development of complete vehicles for many companies, and will be gradually introduced to the market.

From January to July this year, Quanchai achieved a total of 289,000 units of multi-cylinder diesel engines, an increase of 18.3% year-on-year, ranking third in the domestic four-cylinder diesel engine industry. The first place in the small and medium power market segment.

"In the face of market competition, Quanchai's future development must take a qualitative growth model, accumulate and precipitate its own core technologies, improve product manufacturing capabilities, and strive for excellence in product quality, and return every user with unparalleled enthusiasm. Chairman Xie Li said.

For diesel engine companies, to continue to expand the market scale mainly depends on improving product quality and service capabilities. When Quanchai entered the multi-cylinder diesel engine industry in 2001, it pursued the development strategy of “speed and scale” to achieve the first phase of its strategic goals. In the process of continuous development, Quanchai realizes that it will participate in future market competition, and must constantly improve product quality, master product core technologies, adjust product structure, and transform enterprise development methods.
