摘　　要：为了满足现代舰船向高速化、大型化方向发展,作为主动力装置的柴油机广泛采用废气涡轮增压器来提高其输出功率。增压器喘振是船用柴油机常见故障之一,文章详细介绍2起增压器喘振故障现象及排除过程,根据喘振机理建立喘振故障树,分析喘振原因,为舰用柴油机科学管理与使用提供建议。In order to meet the requirements that modem ships develop towards high-speed and large scale, exhaust gas turbocharger are widely used in diesel engine as main power device to increase the output power. As one of the common faults, surging of turbocharger often happens on marine diesel engine. In this article, two kinds of treatment are introduced to turboeharger surging, the fault tree is built up on the basis of its mechanism, the fault cause is analyzed and some advice is given for scientific use and management of marine diesel engine.
