【摘要】 测量分析小型手摇起动柴油机冷起动过程的瞬时转速、喷油及燃烧过程特征参数在每一循环中的变化情况;研究供油提前角变化时,这些参数的变化趋势;观察柴油机起动初期和转速增大后,循环喷油量和平均指示压力的变化。更多还原

【Abstract】 The engine transient speed, fuel injection, combustion process and the cyclic variations in some performance indexes are investigated on a small single cylinder diesel engine during cold-starting. It is analyzed that the relationship between the amount of fuel injected and the indicated mean pressure during cold-starting process.更多还原
