【摘要】 研究了喷油嘴流量系数变化对单缸直喷柴油机性能的影响。结果表明,增大流量系数对ZH1105柴油机标定工况和低速大转矩工况的烟度和燃油消耗率有明显影响。通过对燃油喷雾的分析,揭示了流量系数影响柴油机性能的原因。更多还原

【Abstract】 The influence of flow coefficient changes on ZH1105 diesel engine is studied in this paper.The experiment results show that enlarging the flow coefficient of spray can make a remarkable effect on the smoke emission and fuel(consumption) while the engine at low speed and heavy load or at declared working conditions.Through the analysis of fuel spray,the reason that how the flow changes affect the engine performance is illustrated.更多还原
