摘要
船用双燃料柴油机在燃气模式转换过程中出现故障的原因多种多样.例如,引燃油偏差高可能导致燃气触发系统异常;单缸敲缸可能导致燃气触发的故障;燃料模式选择错误也可能导致燃气转换失败.此外,主燃气压力建立时间过长、燃气质量差、气阀打开时间到达设定值、气量不足等因素也可能影响正常的转换过程.另外,废气阀故障也可能引发此类问题.本文介绍了一例双燃料柴油机燃气阀绝缘低导致无法转换燃气故障的案例.经过轮机管理人员的不懈努力和钻研,成功解决了这一问题,为双燃料柴油机的故障排除提供了有价值的参考.
Abstract
There are many reasons for the failure of Marine dual-fuel diesel engines in the process of gas mode conver-sion.For example,generator pilot fuel press reference deviation high may lead to gas trip;generator knock status cylinder may lead to gas trip;generator illegal fuel mode selection can also result in failure of gas trip.In addition,the main gas pres-sure establishment time is too long,the gas quality is poor,the opening time of the gas valve reaches the set value,the gas volume is insufficient and other factors may also affect the normal conversion process.Moreover,waste gas valve failure can also cause such problems.This paper introduces a case of a dual fuel diesel engine whose gas admission insulation is low,re-sulting in failure to convert gas model.Through the unremitting efforts and research of the Marine engineers,this problem has been successfully solved,which provides a valuable reference for the troubleshooting of dual-fuel diesel engines.
