摘要
采用微机化大气模拟综合测量系统对自然吸气柴油机运行在不同海拔地区下的性能进行了研究。分析和比较了不同海拔下的柴油机负荷特性、速度特性、万有特性以及碳烟排放特性的关系。同时,在不同大气压力下的等过量空气系数条件下,比较了动力性和经济性之间的关系。
Research and study on performances of natural- aspirated diesel engine vehicles run in different altitude regions are conducted by a computerised atmospheric simulation and comprehensive measuring system.The relationships between load characteristic,speed characteristic,gravitation characteristic and carbon smoke exhaust characteristic of diesel engine are analyzed and compared,the relationship between power ability and economy is also compared under the condition of constant extra air coefficient at different atmospheric pressures.
