摘要:

为了降低某柴油机机油消耗和寻求改进措施,采用数值仿真分析和试验相结合的方法,对该发动机活塞环组窜气量和机油消耗特性进行分析研究.建立该发动机活塞环组动力学及机油消耗(LOC)预测模型,并通过试验数据对模型进行标定.指出通过各环岸及环槽间的压力、活塞环的轴向运动,来判断导致机油消耗增大或减小的原因,并用于指导改进设计工作.另外,研究各环岸与气缸壁之间的间隙对机油消耗的影响,对该发动机活塞型线和活塞环进行改进设计.改进前后对比试验结果发现,改进后机油消耗明显改善,仿真结果和试验结果变化趋势一致.

Abstract:

By synergetic use of numerical and experimental methods the characteristic of flow-by and lubricating oil consumption (LOC) of one diesel engine was analyzed in order to reduce the engine LOC and provide the improved solution. The predicting model on piston ring package dynamic and LOC was established and calibrated by test data. It shows that the results of interring pressure and axial ring motion can be used to determine the reason that cause either an increase or decrease of LOC and guide improvement design work. In addition, the effects of the clearance between piston land and liner surface on LOC was investigated, and the piston profile and first ring were modified. The test shows that LOC changed significantly after modified, and it has good consistency between simulation results and experimental results.
