应用光电法测量火花点火式发动机的火焰传播

Measurement of Flame Propagation in a Spark-Ignition Engine by Using Optoelectronic Measuring Technique

本文提出了一种测量火花点火式发动机火焰传播的新方法——光电测量法。应用这种方法对一台东风EQ6100型汽油机燃烧过程的火焰传播进行了测量,表明该方法实用性强、测试方便、分辨率较高。有较强的抗干扰能力,可用于研究汽油机的火焰传播性质及发动机运转参数对火焰传播的影响。

This paper presents a new measuring technique-optoelectronic measuring technique to investigate the flame propagation characteristics in spark-ignition engine. The measurement results of flame propagation on Dongfeng EQ6100 gasoline engine show that the optoelectronic measuring technique with high resolution factor and anti-interference ability is practical and convenient for use. The flame propagation characteristic and the effects of the engine operating parameters on flame propagation can be studied by using this measuring technique.
