TL;DRAbstract

The UE engine is the only Japanese-developed low speed diesel engine since 1955. In this paper, the latest developments and technologies of UE engines are explained. The engine program, the latest LSE series in particular, is introduced first, followed by a discussion on the UEC Eco-Engine, an electronically controlled engine, which entered service in June 2005. This engine has excellent service results without any emergency vessel stop even up to the present. Finally, focus is given on the ECL system, an electronically controlled cylinder lubricating system which quite effectively reduces cylinder oil consumption, and which has also received good service results.
