Natural gas fuel power system technology is becoming one of the main countermeasures for the shipping industry to cope with the increasingly stringent emission regulations and achieve sustainable development. At present, natural gas-diesel dual-fuel engine is the most widely used mode in China’s inland shipping industry, and the initial conditions have a crucial influence on the combustion in the engine cylinder. This paper is based on different initial conditions to carry out related research. The research results show that the initial pressure and initial temperature of fuel in cylinder had a greater influence on the flow velocity, fuel burning time with the increase of the initial temperature and pressure of the cylinder in advance, NOx, CO and HC emissions change, according to the engine cylinder combustion and emission characteristic comprehensive analysis, the best operation condition is the initial temperature of 360 k, the initial pressure of 0.19 Mpa.
