火花塞离子电流包含大量发动机缸内燃烧信息,基于其产生的机理阐述了火花塞主要结构参数如电极结构、点火电压以及点火正时等对离子电流的产生以及检测方面的影响;同时,分析了偏置电压以及发动机缸内燃烧状况对离子电流产生与检测的影响。对火花塞间隙0.8mm、0.9mm和1.0mm时定量探讨了偏置电压与离子电流的关系,即间隙越小测量敏感程度越高。
火花塞離子電流包含大量髮動機缸內燃燒信息,基于其產生的機理闡述瞭火花塞主要結構參數如電極結構、點火電壓以及點火正時等對離子電流的產生以及檢測方麵的影響;同時,分析瞭偏置電壓以及髮動機缸內燃燒狀況對離子電流產生與檢測的影響。對火花塞間隙0.8mm、0.9mm和1.0mm時定量探討瞭偏置電壓與離子電流的關繫,即間隙越小測量敏感程度越高。

Briefly expounds the mechanism of spark plug ion current, the impact of the plug’s main structure parame-ters such as electrode structure, the spark plug ignition voltage and ignition timing on ion current and detecting were re-searched; At the same time, researched the influence for instance the bias voltage and engine cylinder combustion condi-tion on the ion current produce and testing. When the spark plug gap was 0.8 mm, 0.9 mm and 1.0 mm, quantitative re-searched the bias voltage and the relationship between the ion current, get the conclusion that the smaller clearance, the higher measurement sensitivity.
