早在1960年,苏尔寿公司就在二冲程十字头型柴油机上进行了燃烧天然气的研究,开始了双燃料船用发动机的研究工作。到1986年为止,经过了设计改进、研制试验和实船试用阶段,已经作为同型号柴油机的姊妹机种投放到市场上参加船用主机的竞争了。尽管双燃料低速发动机比汽轮机的经济效益好,有较高的燃用经济性,但是,过去由于此型机受到爆燃敲缸极限的限制,影响了 As early as 1960, Sulzer conducted research on natural gas combustion on a two-stroke crosshead diesel engine and started research on dual-fuel marine engines. By 1986, after the design improvement, development test and real-trial phase, it had been put on the market as a sister model of the same type of diesel engine to compete in marine mainframes. Although the dual-fuel low-speed engine is better than the steam turbine economic efficiency, higher fuel economy, but in the past because of this type of machine by knock knock cylinder limit, affecting
