Development of Pure Marine Gas Engine (EYG26L)

Abstract

The environmental impact of gas engine emissions such as NOx, PM, SOx and CO₂ is significantly lower than that of diesel engines. Furthermore, the cost of gaseous fuel is lower than that of heavy fuel, and this cost difference will continue to increase. Focusing on these advantages, the gas engine is expected to be used as a marine power source. On the other hand, in the practical application of gas engines to marine use, maintaining combustion stability during variation in load and fuel composition is a problem that needs to be considered. YANMAR has developed a new marine gas engine. This paper introduces the new engine profile and describes new technologies that addressed previously described problems.
