摘要
利用 AVL -65 0 1发动机燃烧分析仪记录了液化石油气 (L PG ) /柴油双燃料发动机和原柴油机在不同工况下的示功图并进行了放热规律分析 .结果表明 :L PG/柴油双燃料发动机与原机相比 ,低负荷时最高燃烧压力及最高压力升高率较小 ,高负荷时升高率较大 ;滞燃期略长 ;燃烧持续期短 .根据这些特征对 L
In this paper, the indicator diagrams of LPG/diesel dual fuel engine and an original diesel engine are measured by AVL 6501. Combustion analyzer and analysis on combustion characteristics have been done .The experiment results show that peak combustion pressure and pressure increasing ratios of the dual fuelare are lower than that of the diesel engine under light load, but higher than that under heavy load. The dual fuel engine has longer delay combustion periods, shorter fast combustion periods than the diesel engine. According to these characteristics, dual fuel engine will have good properties by effective adjustment.
