| 英文摘要 | In diesel-ignited natural gas marine dual-fuel engines, the pilot diesel injection timing (PDIT) determines the premixing time and ignition moment of the combustible mixture in the cylinder. The PDIT plays a crucial role in the subsequent development of natural gas flame combustion. In this paper, four PDITs (??8°CA, ??6°CA, ??4°CA, and ??2°CA) were studied. The results show that the advancement of PDIT increased the engine's power, thermal efficiency, and natural gas flame spread velocity, and increased NO emissions and CH 4 emissions of the marine engine. The PDIT affected the ignition delay period and the rapid combustion period to a greater extent than the slow combustion period and the post combustion period. With each 2°CA advancement of PDIT, the engine's power increased by 69.87kW, thermal efficiency increased by 0.42%, radial flame spread velocity increased by 2m 4 emissions increased by 3.75%. |
