LPG/柴油双燃料在船柴上的试用和性能学习

Performance Study of Marine Diesel with Dual Fuel of LPG and Diesel Oil

将船用4D42增压、中冷、直喷型柴油发电机改进为燃用LPG/柴油双燃料能源发动机进行了实验与性能测试.结果表明,采用机电联合控制双燃料发动机与原柴油机相比,动力性能基本相同,排放烟度大幅度改善,但CO,HC,NOx排放量有所不同.

This paper introduces the experiment study of LPG- diesel dual - fuel engine refitted from 4D42 marine supercharged diesel engine. The result indicates that, compared with the diesd engine, when the dual - fuel engine adopts the mechanical coordinated control, its power is not obviously changed and emitting smoke is substantially improved, but the emission of CO, HC and NOx are increased obviously.
