| 目的 研究柴油机缸内漏气状况对柴油机动力输出性能的影响。方法 针对150 mm缸径单缸柴油机，采用加装模拟漏气装置以及在GT-suit中建立模拟漏气的单缸机工作过程仿真模型的方式，研究不同漏气面积开度对单缸柴油机缸内最大爆发压力、功率以及有效比油耗的影响。结果 在同一工况下，随着模拟漏气装置开度的增加，单缸机的最大爆发压力的最大降幅为7.22%，功率的最大降幅为7.02%，燃油消耗率的最大增幅为5.70%。结论 在同一工况下，随着模拟漏气装置开度的增加，单缸柴油机的缸内最大爆发压力和功率随之显著下降，有效比油耗上升。 |

| Objective To study the influences of air leakage in cylinder on power output performance diesel engine. Methods A 150mm cylinder single cylinder diesel engine was studied by adding a simulated air leakage device and establishing a single-cylinder engine simulating working process model with air leakage in GT-suit, to study the influences of different opening area on the maximum in-cylinder burst pressure, output power and effective fuel consumption of a single cylinder diesel engine. Results Under the same operating conditions, with the increase of the opening area of the simulated air leakage device, the maximum drop of in-cylinder burst pressure and output power of the single cylinder diesel engine was 7.22% and 7.02%; and the maximum raise of the effective fuel consumption was 5.70%. Conclusion Under the same operating conditions, with the increase of the opening area of the simulated air leakage device, the maximum in-cylinder burst pressure and output power of the single cylinder diesel engine drop significantly, while the effective fuel consumption rises. |
