Shaanxi Chai Heavy Industry developed a new power diesel engine

The first 6DK-28 diesel engine developed and produced by Shaanxi Chai Heavy Industry Co., Ltd. successfully passed the approval of China Classification Society and shipowners recently, which marked the successful completion of the localization of this type of diesel engine.

DK-28 diesel engine is a new product developed by Shaanxi Diesel Heavy Industry Co., Ltd. with the patented technology of Japan Daihatsu Diesel Engine Co., Ltd. In order to make the model form a series and ladder production, and broaden the market scope of the company's products, Shaanxi Chai Heavy Industry started 6DK. -28 localization of diesel engines.

In the development process of the first 6DK-28 diesel engine, on the basis of summarizing the experience of localization of 8DK-28 diesel engine, the engineers and technicians thoroughly digested, understood and absorbed the technology of the machine and successfully completed the localization of the machine. Processing of parts and components, assembly and commissioning of diesel engines. After several tests such as gantry running-in test, machine test, back pressure test and exhaust smoke test, the technical parameters of 6DK-28 diesel engine are in compliance with the requirements of the test program, and have passed the approval of China Classification Society and shipowners. .

The 6DK-28 diesel engine has a compact structure and good performance. The rated power is 1912 kW and the highest power is 2100 kW. It can be used as a host for 500 to 600 container ships. The successful development of the machine has filled the blank of the 2000 kW power segment diesel engine of Shaanxi Diesel Heavy Industry Co., Ltd., enriched and optimized the diesel engine series, and laid a solid foundation for the company to enter the broader ship host market.
