A few days ago, the world's first W6X72DF-2.2+iCER host was successfully handed over to CSSC Engine Co., LTD. (hereinafter referred to as CSSC Engine) located in the West Coast New Area of Qingdao, which has become a new achievement in the high-end, intelligent and green development of Qingdao's Marine equipment industry.

    The exhaust gas cycle rate is as high as 50%

    The successfully tested W6X72DF-2.2+iCER host weighs 550 tons, has a maximum sustained power of 21,200 horsepower, and is equipped with iCER low-pressure exhaust gas cycle technology for the first time, with an exhaust gas cycle rate of up to 50%, which is more green and efficient than traditional models. The main engine not only has the dual fuel free switching function, but also has the energy saving and low emission mode under two different fuels, and can operate in a total of 5 modes, which can effectively adapt to the transportation needs of the shipping market in different sea conditions.

    According to Ye Dan, deputy general manager of Qingdao Manufacturing Division of China Shipbuilding Engine, as the world's first model, W6X72DF-2.2+iCER is an ocean-going host developed for the current green and efficient needs of the Marine transportation industry, especially for large LNG transport ships. At the same time, as a new generation of 72DF host, the weight and volume of the host are reduced to varying degrees, which is an important force to promote the green and low-carbon development of ships. The successful delivery of the engine not only enriched the company's engine product spectrum, but also opened the road to the manufacture of new green hosts.

    The main engine will be installed on a 175,000 DWT LNG CARRIER built by Dalian Shipbuilding Industry Group Co LTD for CMES LNG CARRIER. Whether in fuel or gas mode, the engine can meet TierIII emission requirements, and its combustion performance, emission performance, and fuel consumption are further optimized. In addition, the host has a strong market competitive advantage in engine energy consumption, system integration and system security.

    Constantly break through the "stuck neck" problem

    As the backbone enterprise of China's Marine low-speed diesel engine industry, CSSC engine is at the forefront of the country and even the world in the manufacture of more reliable, more intelligent and lower carbon power systems.

    China Shipbuilding Engine Co., Ltd. is the core large-scale professional Marine low-speed engine manufacturing enterprise, located in Qingdao West Coast New Area Haixiwan shipbuilding industry base. In 2017, CSIC integrated its subsidiaries Yichang Chuanchai, Dalian Chuanchai and Qingdao Chuanchai to set up China's largest Marine low-speed diesel engine manufacturing enterprise - China Chuanchai, and changed its name to CSIC Engine in March 2023.

    At present, the company's leading products high-power Marine low-speed engine, widely used in oil tankers, bulk carriers, container ships and other large ocean ships. Relying on decades of technological accumulation and continuous research and development innovation, CSSC Engine has been identified as a national high-tech enterprise, a national "specialized and new" small giant enterprise, with two provincial technology centers and a municipal technology center, and was approved by Shandong Province ship power Technology Innovation Center in 2023.

    "At present, the global energy structure is accelerating its evolution, and the demand for new energy powered ships such as LNG, methanol and ammonia is constantly being generated. We have set up a team to carry out technical research on new fuel engines and their core components, and continue to break through the 'stuck neck' problem, in 2023, the company has obtained a total of 110 national patents, helping the dual-fuel engine orders to exceed 40%." The relevant person in charge of the engine told reporters that the company's current order volume of various types of engines has exceeded 300 units, the production plan for 2024 and 2025 has been full, and it is fully undertaking market orders in 2026.

    "Green machine" helps low-carbon environmental protection

    In addition to the successful verification of the world's first W6X72DF-2.2+iCER host, in recent years, CSSC engine has also achieved a number of industry-first scientific and technological innovation achievements, forming a series of standards and specifications to support the lean quality of products, and continuously providing new momentum for future high-quality development.

    "Ammonia is a clean and low-carbon alternative fuel that has broad application prospects in the field of ship power. Combined with emission post-treatment technology, ammonia fuel engines can reduce carbon dioxide emissions by 95 percent, nitrogen oxide emissions by 85 percent, sulfur oxide emissions by nearly 100 percent, and extremely low particulate matter emissions compared to conventional fuels." According to the relevant person in charge of CSSC engine, the company has actively developed a new low-carbon and environmentally friendly Marine engine fueled by methanol and ammonia through collaborative innovation in recent years, among which, the ammonia fuel engine will use cylinder high pressure direct injection technology, the use of diesel ignition technology to solve the problem of high spontaneous combustion temperature ignition difficulties. The first ammonia-fueled engine developed by CSSC is expected to be delivered in 2025.

    "At present, we have achieved the batch manufacturing and delivery of LNG dual-fuel low-speed machine, the next step, will continue to vigorously promote methanol, ammonia and other low-carbon zero-carbon project business negotiations and cooperation, methanol and ammonia fuel host will be the first in the country and the world's first system, fully support the proportion of high value-added products to increase, at the same time, relying on digital transformation and other advanced management improvement programs, Continue to improve the total delivery, profitability, and all-round product competitiveness." The relevant person in charge of the ship engine said.
