内燃机从燃烧柴油改变为燃烧重油会对联轴节产生严重的影响,例如,当一台渡轮的32缸双发动机改变燃油时,有27根进油管随即损坏,这就意味着相应的气缸不能进油而失去平衡,结果导致共振增加并在联轴节上产生很高的负荷。不仅发动机和联轴节将承受超负荷,连齿轮箱也受到一定程度的超负荷影响。燃油系统在使用柴油时问题较少,采用重油后问题陆续发生,主要的原因是排气阀、滤器、喷射泵、喷咀以及凸轮轴发生故障和损坏,以至发动机联轴节会突然产生意想不到的问题.船级社和发动机制造厂注意到了这种情 For example, when a 32-cylinder twin-engine engine changes fuel on a ferry, 27 inlet pipes are immediately damaged, which means that the corresponding cylinder can not enter the oil. The loss of balance results in increased resonance and a high load on the coupling. Not only will the engine and couplings be subject to overload, even the gearboxes will be affected by a certain degree of overloading. The problem with the fuel system is that it is less problematic when it comes to the use of diesel. The main problems that occur after using heavy oil are the failure and damage of the exhaust valves, filters, jet pumps, nozzles and camshafts, as well as the sudden occurrence of unexpected engine shaft couplings The problem has been noticed by classification societies and engine manufacturers
