CSSC Power delivered the world’s first new-generation intelligent control dual-fule Main Engine

On June 3, the world’s first 7X62DF-2.1 dual-fuel main engine with intelligent control exhaust gas recirculation (iCER) system was developed by CSSC Power (Group) Co., Ltd., a subsidiary of China State Shipbuilding Corporation, was located in China (Shanghai) Free Trade Zone. Shanghai CSSC Mitsui Shipbuilding Diesel Engine Co., Ltd. in Gangxin Area was completed and delivered. As a key product presented to the 20th National Congress of the Communist Party of China, the successful development of this product not only enriches the type spectrum of my country’s dual-fuel main engine but also enhances the market competitiveness. The dual-fuel engine R&D and manufacturing field continued to maintain its leading edge.

The 7X62DF-2.1 is equipped with the iCER system developed by WinGD, a subsidiary of China State Shipbuilding Corporation, with a maximum continuous power of 15,400 kilowatts, which can reduce greenhouse gas emissions by more than 28%. Natural Gas (LNG) Dual Fuel Powered 7000 Vehicle Car Carrier (PCTC).

The successfully installed application of the iCER system provides a new practice and case for further reducing the greenhouse gas emissions of marine engines. Its biggest advantage is that the air and gas ratio is automatically tracked and dynamically adjusted by a specific algorithm, reducing methane escape in gas mode by 50%. Under the current trend of increasingly stringent green environmental protection and low carbon, it is expected to become a new type of host favored by the market.

The Assembly of the project began in February of this year. Due to the impact of the epidemic, personnel arrangements and material transportation were once difficult. The project team carried forward the spirit of “hard work, sincerity and self-improvement” of CSSC people, and the core personnel voluntarily stationed at the production site and worked together to overcome one problem after another. In the whole manufacturing process, the company goes from marketing to manufacturing, from design technology preparation to the integration of supporting resources, from equipment guarantee to the implementation of the production plan, all of which are closely linked and meticulous.

Since May 10, CSSC Mitsui has been focusing on epidemic prevention and control on one hand, and the whole machine test on the other. It has been working hard at night and in lean management, showing professionalism, professionalism, and dedication everywhere. Actively coordinate with various suppliers to ensure the complete supply of the iCER system, water treatment system, and remote control system. Actively cooperate with various service providers to ensure the performance debugging of the host under various working conditions. Actively contacted and confirmed that representatives of shipowners, classification societies, and shipyards were stationed in advance, deeply participated in verification, testing and delivery, and jointly witnessed the birth of the world’s first CMD-WinGD 7X62DF-2.1 main engine and shared this glorious moment.

It is understood that the dual-fuel main engine using the iCER system will have a wider application prospect. It can be installed not only on large car carriers but also on large LNG carriers, super large container ships, and other ship types. At present, CSSC has ordered more than 60 engines equipped with the iCER system.

At present, the cadres and employees of CSSC are working together to coordinate the prevention and control of the epidemic and the resumption of work and production. In the future, CSSC will continue to devote itself to the independent research and development of more technologically advanced and green marine power equipment, so as to provide strong power for Chinese ships to build China into strong shipbuilding and marine power.

中船动力集团交付全球首台新一代智能控制双燃料主机

6月3日，由中国船舶集团下属中船动力（集团）有限公司研制的全球首台带智能控制废气再循环（iCER）系统的7X62DF-2.1双燃料主机在位于中国（上海）自由贸易区临港新片区上海中船三井造船柴油机有限公司完工交付。作为向二十大献礼的重点产品，该产品的研制成功不仅丰富了我国双燃料主机的型谱，提升了市场竞争力，也标志着中国继全球最大船用双燃料低速机X92DF之后，在船用低速双燃料发动机研发制造领域继续保持了领先优势。

7X62DF-2.1配置了中国船舶集团旗下WinGD公司研发的iCER系统，最大持续功率15400千瓦，可减少28%以上温室气体排放，将作为主推进装置安装在招商局金陵船厂为日本NYK船东建造的液化天然气（LNG）双燃料动力7000车汽车运输船（PCTC）上。

iCER系统的成功装机应用为进一步降低船用发动机温室气体排放，提供了新的实践和案例。其最大优势是，通过特定算法自动跟踪并动态调整空气和燃气比例，使气体模式下的甲烷逃逸降低50%。在当下日益严苛的绿色环保低碳的大趋势下，有望成为市场青睐的新型主机。

该项目于今年2月开始组装。由于受疫情影响，人员安排和物资运输一度困难重重。项目组发扬中船动力人“艰苦奋斗，至诚自强”的精神，核心人员自觉自愿驻守生产现场，齐心协力攻克一个又一个难题。整个制造过程中，公司从市场营销到生产制造，从设计技术准备到配套资源整合，从设备保障到生产计划落实，环环相扣，丝丝入微。

自5月10日起，中船三井一手抓疫情防控，一手抓整机试验，星夜兼程，精益管理，处处展现了专业、职业和敬业素养。积极协调各供应商，确保iCER系统、水处理系统和遥控系统的完整性供货。主动协同各服务商，确保主机在各种不同工况下的性能调试。主动联系落实船东、船级社和船厂代表提前进驻，深度参与验证、试验和交付，共同见证了全球首台CMD-WinGD 7X62DF-2.1主机的诞生，共享这一荣耀时刻。

据了解，采用iCER系统的双燃料主机，其应用前景将更为广泛。不仅可安装于大型汽车运输船，还可安装在大型LNG运输船，超大型集装箱船等船型上。目前中船动力集团手持配置iCER系统的发动机订单已有60余台。

当前，中船动力集团干部职工正上下一心，统筹企业疫情防控和复工复产,坚持目标不变、任务不减、劲头不松，力争把疫情影响的进度抢回来。未来，中船动力集团将持续致力于自主研制更多技术先进、绿色环保的海洋动力装备，为把中国建设成为造船强国、海洋强国提供中国船舶的强劲动力。
