The authors have succeeded in developing a new technology which makes it possible to use lubricating oil (LO) semi-permanently without oil renewal and without waste oil. The technology was developed based on the authors' belief that LO oxidation is negligible and that LO may be used semi-permanently if sludge removal is speedy enough and LO is always kept clean. The technology is called kidney system and it has been working well in more than 1000 units of marine and cogeneration diesel engines, in many hydraulic machine com-panies and in many machine work-shops Kidney system has been working better than expected in cleaning performance of LO, no waste oil, decrease of LO consumption, increasing load capacity of LO, remarkable reduction of machine troubles, longer life of engines and so on. This paper explains and considers why kidney system is so effective. The paper also shows some new fields where kidney system can be applied. Application to automobiles already started in Tokyo Metropolitan Transportation Agency and the authors hope that kidney system will be widely used in automobiles in the near future.
