Zhongchai Power's own brand marine medium speed diesel engine was successfully developed

Under the strong support of the Ministry of Industry and Information Technology, the Ministry of Finance and other national ministries, China Shipbuilding Power Co., Ltd. integrates the high-quality resources of the Unit 71, Shaanxi Diesel Heavy Industry Co., Ltd. and Chongqing Hongjiang Machinery Co., Ltd. The specialized marine diesel engine project company established according to the modern enterprise model has the high-quality R&D and manufacturing resources of domestic marine diesel engines, and is responsible for the research and development of self-owned brand medium-speed diesel engines, brand planning and promotion, supply chain construction and after-sales service.

In 2008, Chai Power officially launched the first 6CS21/32 marine medium-speed diesel engine development project with independent intellectual property rights in China, and determined the core spectrum of the series, the core technical indicators of the first product, the main structural features, and the main supporting parts supply methods. And the R&D cooperation model, etc., and the officially named product series name is "CS". After three years of hard work, the company has finally completed the research and development, design, manufacture and verification of its products and passed the certification of China Classification Society.

The 6CS21/32 medium speed diesel engine has a cylinder diameter of 210mm, a stroke of 320mm, an output of 1320kW, and a rotational speed of 900 to 1000 rpm. It can be used as a propulsion power for inland rivers, offshore vessels, ro-ro ships, and offshore vessels, ro-ro ships, ocean-going vessels, Generator set prime mover for offshore platforms. The products have outstanding technical advantages and characteristics, advanced technical indicators, excellent economics under full load, fuel consumption rate superior to existing international advanced products; meet the requirements of harsh international environmental protection regulations. Emissions meet the requirements of the International Maritime Organization's IMOTier II emission requirements and are below the limit of 15%, while having the potential to meet the requirements of the next phase of IMOTier III. In the design, according to the domestic materials and manufacturing process level, the localization rate of the first machine parts exceeds 60%, and the localization rate after batch production will reach more than 90%.

The successful development of the self-owned brand medium-speed diesel engine is conducive to the upgrading of China's diesel engine products and promote the improvement of China's diesel engine technology.
