If impurities (i.e. metals) are found, it means something wrong with the bearing and crankshaft. If the viscosity is lower than the standard, it may mean that fuel oil may have leaked into the lube oil system. Too much fuel oil in the lube oil system can lower the flash point of the lube and also may lead to possible explosion. The important figure is TBN.

轮机长大管轮面试指南
轮机长/大管轮面试指南轮机长面试问题及参考答案轮机长是轮部的第一把手，也是船上仅次于船长的重要管理人员。
实践表明，没有很好的轮机长是很难保证船舶的安全的。
目前，世界主要船队的船舶老化问题相当严重，而要保证大龄船舶的营运安全，没有很好的轮机班子是很难实现的。
因此，船东在面试船员时轮机长往往是他们考核的重点。
特别是东南亚的很多船东公司，他们对轮机长的考核从技术到管理，每一环都很严格。
对轮机长的经验、技术和解决实际问题的能力尤其相当重视。
我们认为，轮机长不但要有丰富的经验、灵活的头脑，也要有很好的管理能力和团队工作精神，只有这样，才能管好轮机班子，才能和船长以及甲板部的管理工作配合好。
另外，经验表明，相对船长和甲板部队的人员而言，轮机长的英语相对稍弱一些，希望在业余时间下苦功练习英语听力和写作。
面试时主要是看你的听力理解，而在国外船上干时主要是做一些英文的确PAPER WORK，另一方面，随着ISM的生效和强制实施，PSC检查和EXTRA AUDIT方面的审核都要求一定的听力和书写方面的能力。
下面的一些问题不但有技术方面的，也有很多是管理方面的，请轮机长在阅读时能举一反三，联想到其他船东可能考到的问题。
1. Can you tell something about your last ship? What types (brands) of main engine have you ever experienced?My last ship (type of engine, horse power, trading area, GRT/DWT, etc.)I have experience with several different types of main engines, such as Sulzer, B&W, MAN, PC etc.2. What abilities should a Chief Engineer possess?First, I think it is very important for a Chief Engineer to be skillful and proficient at work. Second, he should maintain good management in the engine department. Third, he should be able to try to motivate every person under his management by assigning jobs fairly among them. Fourth, he needs to be good in English and language communication. Last, it is very important for a Chief Engineer to maintain good relationship with the Master, the technical superintendent and other personnel from company, First Engineer and the Chief Officer. Above all, he should listen to orders from the Master in most cases.轮机长不是船上的轮机总工程师，也是仅次于船长的重要的管理人员。

(64)在坞修中，安装尾轴和螺旋桨时，船方在场监修人员应是轮机长。
(65)柴油机气缸套的磨损量只要在 0.4%—0.8%范围之内，气 缸套就处于正常工作状态(D 为缸径)。
(66) 气缸盖冷却面上裂纹是气缸内最大爆发压力引起的周期性脉动应力作用的结果。
(67) 当发现气缸盖的底面出现龟裂裂纹时，可断定为热疲劳裂纹。
(68)拆卸主机喷油器时，如果出现针阀偶件卡死现象，应使用轻柴油浸泡来拆卸。
气缸套内圆表面的轻微拉痕可用油石、 锂刀或风砂轮钳工修磨。
吊缸检修柴油机连杆螺栓时一定要磁力探伤或着色探伤。
尾轴承密封装置油压试验是采用重力油柜润滑油，从泵油(69) (70) 柴油机气缸套冷却侧裂纹常发生在外圆表面上部凸缘根 部。
(71) 换新活塞环后，必须进行20—24小时的磨合运转才能投入使用工况。
(72)新造和大修后的曲轴均应进行平衡试验， 以保证柴油机工作平稳。
所以，一般中、低速柴油机曲轴进行静平衡试验，高速柴油 机曲轴进行动乎衡试验。
(73) 浸油法检查气阀气密性，浸油时间为 10分钟。
(74) (75)至回油连续3min之内不准漏油。
(76)轴承在增压器中居重要地位，它不仅保证转子安全可靠地高速回转，还必须保证转子准确定位。
(77)船舶在油船货油舱船侧破舱进水时，其危险性最大。
(78)堵漏的警报信号是：二长声，一短声，连放一分钟。
(79)船舶摇摆周期的大小，与哪些因素有关：①船的大小、形状；②排水量；③装载情况。
(80)船舶生活垃圾未经粉碎处理，可在距最近陆地12海里以外投弃入海。
(81)油类记录簿用完后，应留船保存三年。
(82)我国船检规定，空气瓶安全阀的开启压力应不超过最大工作压力的1.1倍。
(83)ISM规则目标包含三层意思，ISM规则总目标、公司的安全管理目标、安全管理体系目标，试问安全管理体系目标是：①符合强制性规定与规则；②对有关机构、组织所建议的适用的规则、指南、及标准予以考虑。
(84)当PSC 官员按照船舶操作性要求检查船员的消防演习时，检查的项目可包括：①观察船员如何将火警报告给驾驶台；②观察消防组启动灭火设备扑灭模拟火源；③观察消防员正确穿戴防护服，确认消防器具是否齐全；④伤员急救措施。
(85)STCW78/95公约新增加的STCW规则B部分，在保持轮机值班的指导中规定“特别重要”的是指负责值班的高级船员要认识到有效地履行其职责对海上人命财产和防止海洋污染的必要性。
