| 摘 要： | 对坦克柴油机排气噪声测试信号进行了时域特殊处理，从反映不同状态下信号峰值间隔变化的角度提取特征参数．建立了一种适用于实车不解体检测的各缸工作不均匀性评价新方法。试验结果表明，该方法切实可行。

| Abstract: | In this paper, the testing signals of tank diesel engine exhaust noise were processed in time analysis. By extracting feature parameter form the interval of signal peak, a new method of evaluation for cylinder-to-cylinder nonuniformity with nondisassembly examination was put forward. The experiments indicated that this method was effective and feasible. |
