摘要

本文分析了喷油器开孔压力的变化对压缩点火发动机工作值的影响,包括油烟的温度。考虑到现有的试验台和测量能力,描述了一种实验研究方案。介绍了进行实验测量的试验台的结构。介绍了在现有试验发动机上引入喷油器开孔压力实际修改的方法。提出利用Fisher-Snedecor (F- s)分布的F统计量来评价喷油器开孔压力变化对烟气流动比焓影响的重要性。对测量结果进行了定性和统计研究。从烟气温度快速变化的过程出发,对压缩点火发动机单循环烟气的比焓进行了分析。介绍了这些研究的结果,并讨论了在压缩点火发动机参数诊断中采用这种评估方法的可行性。

Adoption of the F-statistic of Fisher-Snedecor distribution to analyze importance of impact of modifications of injector opening pressure of a compression ignition engine on specific enthalpy value of exhaust gas flow
This article analyzes the effect of modifications of injector opening pressure on the operating values of a compression ignition engine, including the temperature of the fumes. A program of experimental investigation is described, considering the available test stand and measurement capabilities. The structure of the test stand on which the experimental measurements were conducted is presented. The method of introducing real modifications of injector opening pressure to the existing test engine was characterized. It was proposed to use F statistic of Fisher-Snedecor (F-S) distribution to evaluate the importance of the impact of modifications of injector opening pressure on the specific enthalpy of the flue gas flow. Qualitative and statistical studies of the results achieved from the measurements were carried out. The specific enthalpy of the fumes for a single cycle of the compression ignition engine, determined from the course of rapidly variable flue gas temperature, was analyzed. The results of these studies are presented and the usable adoption of this type of assessment in parametric diagnosing of compression ignition engines is discussed.
