摘要
对预混型天然气发动机的调速率控制进行论述,对优化瞬态调速率的问题进行分析,给出了根据转速变化率来修正点火提前角这一具体的瞬态调速率优化方法。针对瞬态调速率优化前后的突加与突减工况,对预混型天然气发动机转速变化情况进行对比,进而确认瞬态调速率的优化效果。
The control of speed governing rate of the premixed natural gas engine was discussed.The issue on optimization of transient speed governing rate was analyzed.The specific optimistic method for transient speed governing rate based on the modified spark advance angle against relative speed variation wais given.The speed variation of the premixed natural gas engine before and after the acceleration and deceleration due to optimization of transient speed governing rate was compared,and the performance of transient rate optimization was confirmed.
