As the world's leading engine manufacturer, Dongfeng Cummins Engine Co., Ltd. has been focusing on the Chinese market, accurately grasp the needs of users, and constantly realize the expansion of the application of the product. It is reported that the application of Dongfeng Cummins QSZ13 power generation engine has been expanded to a new level. It has achieved bulk installation on the air compressors of two sand-catching shipyards in Chongqing.

QSZ13 engine batch installed

Up to now, the Chongqing sand-carrying vessel has completed the QSZ13 engine batch installation and equipped with Tianyuan remote monitoring system for real-time equipment monitoring.

Application match new breakthrough

In recent years, with the further advancement of the country's new round of reforms, infrastructure constructions such as railways, highways, and real estate have been rapidly developed, and at the same time it has led to the rapid growth of aggregate consumption of sand and aggregate. As river sand is an important source of aggregates, the demand is also rising.

However, in the face of growing market demand, the difficulty of extracting sand and sand is becoming more difficult. Since then, a new process using air compressor negative pressure sand suction came into being. With strong suction, convenience and speed, it has been highly praised, and has been widely used in the Yangtze River Basin. The air compressor suction sand on the engine is very harsh, especially in terms of power and stability. In the early days, the Chongqing Sands Shipyard used foreign brands of air compressors, all using imported engines, expensive equipment, and high fuel consumption costs.

Cummins QSZ13 engine

In order to serve this emerging market and expand product applications, Dongfeng Cummins has launched the QSZ13 engine product, and jointly with Zhejiang Kaishan Compressor Co., Ltd., pioneered the market development in Chongqing Wanzhou area. Dongfeng Cummins QSZ13 engine worked continuously day and night, and finally won the favor of users of Chongqing sand-catching fleet with its stable performance, lower fuel consumption and higher working efficiency. Up to now, the QSZ13 engine has been installed at the Yingsha Yingling Project, Wanzhou Yitong, Wanzhou Guangming No. 1 and Other sand mining projects.

“Dongkang QSZ13 engine has good economic performance and stable performance. It has been approved by ship owners and has enabled our equipment to successfully enter this field. It has a place and directly improves the overall market share of equipment. We believe that the cooperation between the two parties will be brilliant. Prospects, said Wang Lixin, general manager of Chongqing Kaishan.

Low cost and high efficiency received praise

“In the past, imported engines were used on the ship. Not only the fuel consumption was high, but also the displacement was smaller than Dongkang QSZ13. The total cost was high. After switching to Dongkang’s machine, not only the fuel consumption was low, but also one machine arrived on two imported machines. The efficiency has increased a lot, and the cost has dropped, the true value!" The users of the Chongqing sand-catching ship have so evaluated the QSZ13 engine.

It is understood that the QSZ13 heavy-duty engine has strong power and adopts Cummins advanced XPI ultra-high pressure fuel injection system. The injection pressure is up to 2400bar. Through precise fuel control and ultra-high pressure injection, the fuel consumption is obviously lower than that of similar products; the combustion chamber is optimized. High-level piston rings and other advanced designs have reduced the fuel consumption and made the engine's smoke level almost zero, perfectly interpreting the concept of “green environmental protection”. This has also become an important reason for its praise.

Nanny personal service

In the past, when customers used imported heavy-duty engines, maintenance was a chronic problem once the equipment failed. The experience of using the QSZ13 engine gave users praise. Considering that this is the first application match in the sand-catching ship industry, Dongfeng Cummins, in order to better ensure the smooth switching of customers' use of new products, in addition to a complete service network service, also specially arranges service engineers to stay and respond to customer needs for the first time. Provide nanny-style personal service; at the same time, regularly communicate with users of Zhejiang Kaishan and sand-shaking vessels to understand the operation of the equipment, collect customer voices, and optimize and improve.

In addition, the remote remote real-time monitoring system installed by Dongfeng Cummins on the QSZ13 engine made the user aware of the status of the equipment. Follow-up, Dongfeng Cummins will also coordinate the training of QSZ engine maintenance and Tianyuan monitoring system for the other two Chongqing service providers and Hubei Langtong service personnel to prepare for the follow-up and timely service needs.

The Dongfeng Cummins QSZ13 engine's entry into the sand mining industry has not only directly boosted the overall sales volume of the QSZ13 engine, but also opened up new markets. It is a chance for the QSZ13 engine to grow, and it is also an important test for the DCEC. New product capabilities. In China, Dongfeng Cummins has been helping China's construction machinery industry with its superior technology and products. In the future, we look forward to Dongfeng Cummins returning to the Chinese market with higher standards of energy-saving products, constantly exploring new application areas, and practicing the world-class strong momentum!
