Friction Reduction Effect Between Piston and Cylinder Surface Treatment Using Floating Liner Engine

抄録

Improvement in thermal efficiency of internal combustion engines has been required, and reduction of the mechanical friction loss is also required for with reduction of the cooling loss or the exhaust loss. This paper was described the structure of the floating liner type piston friction engine used by this research, the method of running-in and setup method of the zero point of measurement data. Furthermore, frictional force was measured using the piston penetrated solid lubricant with surface plastic flow process surface modification, the plateau liner and low viscosity oil, and verified the possibility that there was about 30 to 40% of friction reduction effect.
