description: In this work, we use CONVERGE simulation software to simulate the diesel-natural gas dual-fuel engine operating process, and compare and analyse the effect on the combustion and emission characteristics of the engine at 50%, 60%, 70%, 80% and 90% of natural gas replacement rate, and obtain an optimisation solution. The simulation modeling of the D500 diesel engine is carried out, including the establishment of geometric model, mesh division, configuration of calculation parameters, etc. Combined with the 1D simulation data obtained from RP-TOX software, the calibration and mesh-independent analysis of the simulation results are completed, and the validity of the model is verified. At the same time, the multi-physical fields of the combustion process such as in-cylinder pressure, temperature, flow field and fuel concentration distribution, as well as the causes and emissions of major emissions such as SOOT, NOx, HC, CO and CO2, were analysed and summarised. The study shows that an increase in the natural gas substitution rate will have a first improvement and then deterioration effect on in-cylinder combustion. After a comprehensive consideration, it is concluded that a natural gas substitution rate of 80% will not only significantly replace diesel fuel, but also maintain a similar power level to the original engine, while optimising the emission performance
