摘　　要：介绍了目前多缸柴油机失火故障检测的常用手段。通过对坦克柴油机不同状态下排气噪声信号的双谱分析,提出了一种特别适合实车不解体检测失火故障的方法,并编写了应用软件。试验结果表明,该方法切实可行,不存在安装问题,成本低、操作简单、易于推广。In this paper, many ways of misfire detection for multicylinder diesel engine were introduced. By using bispectrum analysis in the exhaust noise under different conditions of tank diesel engine, we put forward a method that adapt no disassembly to detect misfire special. The experiments indicated that this method is effective and feasible, and have no problem of installation, low cost, simple in implement, easy to generalize.
