Main Article Content
Abstract
In order to reduce CO2 emissions and fuel consumption, the reduction of mechanical friction loss is very important technologies. To reduce such friction loss, understanding the lubrication conditions of engine sliding surfaces are very important. In order to investigate their conditions and to validate the CAE (Computer aided engineering), the author has developed a thin-film pressure, strain, temperature and also thin-film gap sensor and measured the distributions of oil-film condition in sliding surface in machinery main bearings, piston skirts, pinbosses and gear tooth surfaces. In this paper, the structure and form of thin-film sensor especially for piston skirts, plain bearings were discussed and provided a measurement example.
