WinGD 6RT-Flex50D主机使用合规低硫燃油拉缸实例分析

IMO的全球船舶限硫新规已生效,选择燃用合规低硫燃油来应对法规要求的船舶正面临着新型燃油带来的诸多挑战。针对某在航船舶首次使用合规低硫燃油时出现的主机严重拉缸问题,经全面分析拉缸的可能原因,最终确认系所用的某批次合规低硫燃油带入了一定的污染物,致使燃油发火性能变差,最终导致主机拉缸。为了保证船舶继续安全航行,对该问题燃油的使用提出了相应方案。实际应用表明:该方案行之有效,为其它船舶安全使用合规低硫燃油提供了参考。

Case Study on Cylinder Scuffing of a WinGD 6RT-Flex50D EngineUsing IMO Compliant Low-Sulfur Fuel Oil

The latest IMO sulfur limit has come into effect. Ships adopting low-sulfur fuels to meet the regulations of IMO sulfur oxides emissions face lots of challenges. The possible causes of serious cylinder scuffing on a WinGD 6RT-Flex50D marine main engine, which used low-sulfur fuel oil for the first time, was discussed comprehensively. It was found that the scuffing was caused by contaminants in the low-sulfur fuel oil, which led to bad ignition performance of the fuel. To ensure the safe navigation of the ship, the countermeasures are proposed with regard to this batch of fuel. The application results show that this solution is effective, providing reference for ships using IMO compliant low-sulfur fuel oil.
