Abstract

Due to the increasingly serious environmental pollution, new energy technology has received more and more attention. Among the many new forms of energy, liquefied natural gas (LNG) stands out because of its relatively mature technology and sufficient reserves. Its many advantages also make it very suitable for Marine fuel. Liquefied natural gas (LNG) internal combustion engine ships have received more and more attention in the current environment, but due to the technical monopoly and high research and maintenance costs, there are still some deficiencies in combustion and emissions, which have caused some obstacles to the promotion of LNG internal combustion engine. This paper introduces and summarizes some technical solutions in the field of combustion emission of LNG ships, analyses some successful cases of commercial ships, and summarizes part of the development process of LNG internal combustion engine ships, hoping to be helpful to the development of LNG internal combustion engine ships.
