潤滑油の半永久使用清浄法によって非常用発電ディーゼルを確実に起動するエンジン保全システム

抄録

The authors have developed a new technology that enables use of lubricating oil (LO) semi-permanently and reduces LO consumption. This technique always keeps LO clean, just as the kidneys of animals always keep their blood clean. It is, therefore, called a kidney system. The key element of the kidney system is a new type of filter, called a nephron filter. This filter completely removes oxidized LO, which is very sticky and thus increases friction in cold and motionless engines. Diesel engines for emergency electric power fail in many tests of starting which may result from high friction caused by the cold and sticky products built up in LO during the long periods of engine stop. This paper proposes a method that ensures starting of emergency diesel engines by use of a kidney system.
