摘要：

In order to study the effects of adding different proportions of hydrogen in fuel of marine LNG fueled engines on combustion and emissions, a bench test of hydrogen-natural gas-diesel mixed-fired engine was conducted, and the hydrogen ratios under the test load characteristics were 0%, 5%, 10% and 15%. CO, CO2, NO, NOx, and smoke temperature data under four operating conditions were measured. Then for the six working conditions, with hydrogen adding ratios of 0%, 5%, 10%, 15%, 20% and 25%, use CHEMKIN-PRO simulation to calculate the ignition delay time and laminar flame speed. The results show that with the increase of the hydrogen ratio, the combustion ignition delay time in the cylinder is shortened, the maximum temperature in the cylinder and the laminar flame speed increase. The hydrogen adding ratio has no obvious effect on NOx emissions. However, at the same output power, the CO emission is lower under the high hydrogen mixing ratio, and the CO2 emission of fuel mixed with hydrogen is lower than that of pure natural gas. It is considered that the hydrogenation of fuel can improve the combustion and emission of marine LNG-powered engines, and has research and application prospects. © 2020, Editorial Department of Journal of Propulsion Technology.
