汽车发动机点火故障检测仪的应用研究

在新型专利产品──汽车点火故障检测仪的基础上，阐述了三针式汽车发动机点 火故障检测仪的研制、试验及测试应用。研究中采取相应的措施对电场、高频磁场、低频磁 场以及共阻抗干扰进行了有效的屏蔽，减小了火花放电对测试仪器的电磁干扰，确保了研究 的准确性与有效性。

On the basis of a new patent product──detecting instrument for a utomotive ignition fault, the paper explains the research and developing, testin g and detecting application of a three－pin type detecting instrument for automo tive engine ignition fault. In researching and developing,the corresponding meas ures are adopted to shield effectively the electric field,high frequency magneti c field, low frequency magnetic field and anti－interference of common impedance to reduce electromagnetic interference of spark electric discharge on detecting instrument and guarantee the accuracy and effectiveness of research work.
