摘　　要：以B&W 6S35ME-B9型船用低速二冲程柴油机为研究对象,在已搭建柴油机试验平台上展开试验并在线监控采集其状态特征参数,如缸内压力、扭矩、排气温度、缸套冷却水温度、油耗总量和油耗率等,为故障的诊断排除提供有效依据。研究结果表明:基于多个柴油机状态特征参数诊断6号缸高压油泵出口燃油泄漏,有效地提高诊断工作的效率,尤其是船舶柴油机燃油消耗率监控在船上的应用,有效简化诊断过程以提高故障诊断和排除效率。研究内容对未来船舶智能故障诊断有着重要的指导意义。The failure diagnosis experiments are carried out on the B&W6S35ME-B9marine low speed2-stroke diesel engine through analyzing collected on-line status characteristic parameters,such as cylinder pressure,torque,exhaust temperature,cooling water temperature,the total fuel consumption,fuel consumption rate and so on.In the experiments,a fuel leakage from No.6fuel oil pump outlet is identified quickly based on the characteristic parameters.The fuel consumption rate monitoring of marine diesel engines can simplify the engine diagnostic process and improve the diagnosis and troubleshooting efficiency significantly.The research can be meaningful work for the future development of intelligent engine diagnosis system.
