Recently, Anqing CSSC Diesel Engine (ACD), a subsidiary of CSSC Power (Group) Corporation Ltd. (CPGC), has successfully conducted the prototype ignition and initial performance tests of its 6DE28DF dual-fuel engine, verifying its operation in both diesel and natural gas modes.
The test results show that all performance parameters meet the design requirements, indicating that this type of marine medium-speed dual-fuel engine has successfully achieved domestically produced complete machine development after technology introduction, digestion and absorption.
Currently, this engine has secured orders for 12+8 ship sets to power 7,600-CEU PCTCs (Pure Car and Truck Carriers), with deliveries set to begin sequentially from August 2026. The successful development of this prototype has laid a solid foundation for its subsequent commercial application.
To ensure the quality of subsequent mass-produced products and the company’s customer service capabilities, a durability test for this prototype will be launched soon. The test will run continuously until July 2026 to comprehensively assess the reliability of the entire engine and its key components under long-term operating conditions.
It is understood that the 6DE28DF dual-fuel engine has a power range of 1300-1730 kW. It integrates advanced technologies such as variable valve timing (VVT), high-pressure common rail fuel injection and ECU intelligent control, and combines combustion control strategies such as micro-injection ignition, exhaust gas bypass regulation and knock suppression to achieve precise fuel injection and efficient and stable operation under all operating conditions.
This engine adopts multiple safety features including double-walled gas pipes, intake and exhaust explosion-proof valves, gas purging, and leak monitoring, providing systematic assurance for long-term operational reliability and safety.
This dual-fuel engine can be widely used in generator sets of ocean-going vessels such as large LNG carriers, oil tankers, small and medium-sized container ships, providing shipowners with marine power solutions that comply with international environmental protection standards, have excellent operating economy and are guaranteed to be domestically produced.
