| 摘 要： | 采用自行设计的过渡工况控制及测量系统，对舰用电站柴油机进行了加载过渡工况下柴油机的空燃比、消光烟度及示功图参数的测试。试验结果表明，随负荷增加率的上升，空燃比减小，燃烧恶化；燃烧始点后移，预混燃烧比明显下降。上述原因导致了在加载过渡工况下，随负荷增加率的升高，柴油机的性能恶化，油耗增加，燃烧噪声变大，排气烟度上升。

| Abstract: | The air-fuel ratio, smoke opacity and in-cylinder pressure of a marine power plant diesel engine under increasing power transient operating conditions were tested by a home-made control and measurement system. The conclusions show that with the rise of the power increasing rate the air-fuel ratio decreased rapidly, the combustion start point delayed, the premixed combustion rate reduced. All the factors make the performance of diesel engine deterioration, the fuel-consumption, combustion noise and smoke opacity increased with the power increasing rate. |
