| 摘要: |
| 通过多因素全面试验，定量分析研究了半负荷工况下S195柴油机燃油系中柱塞副供油压力、供油提前角和喷油压力等参数对耗油率的影响；用最优化推估方法解决了多因素试验中个别试验值的自然缺失问题。最后就柱塞副磨报后供油提前角和喷油压力的调整策略提出了新观点。 |

| Abstract: |
| The effects of fuel delivery pressure,delivery advance angle and fule-injection pressure in the fuel supply system of S195 diesel engine on the specific fuel comsumption in half load operating mode were quantitatively analized.Several test values missed naturally in the comptehensive tests with multi-factors were established with the optimum method.And new viewpoints about the adjust of the fuel delivery advance angle and fuel-injection pressure were put forward under the condition of plunger wear. |
