中文摘要:
针对航空二冲程直喷式发动机的结构和性能要求,设计并开发了以某型电控机油泵作为核心执行器的智能化润滑系统.结合机油泵的工作原理设计出专用的驱动-反馈系统并对泵油特性进行试验研究.根据发动机的实际需求进行润滑油量的匹配计算和发动机台架试验测定,并对不同气缸的润滑油泵油均匀性进行检测.结果表明该型机油泵的有效泵油脉宽为16~30 ms,润滑系统可以满足二冲程直喷式发动机的润滑要求,泵油均匀性较好.
English Summary:
According to the structural and performance requirements of the aviation two-stroke direct injection engine, an intelligent lubrication system was developed by taking a certain type of electronically controlled lubrication oil pump as the core actuator. The working principle of this oil pump was analyzed, a specialized drive-feedback system was designed and the experimental research on the characteristics of the pump oil was conducted. Aiming at the actual needs of the engine, the matching calculation of the lubricating oil quantity was completed before carrying out the engine bench tests. The uniformity of the lubricating oil of different cylinders was detected. Results show that, the effective oil-pumping pulse duration of the oil pump is 16~30 ms, the lubrication system can meet the lubrication requirements of the two-stroke direct injection engine, and the pumping-oil uniformity is satisfactory.
