Abstract

This paper presents a description of a design methodology which has been employed in the design of a LHR engine. Various combinations of material properties were input and calculations were done to see the effects on the heat flow,thermal stress and maximum working temperature of piston crown. A detail study of piston and liner structure is also conducted by using a two-dimensional nonlinear FEM transient heat transfer model and two-dimensional elastic contact FEM model. Temperature distribution and stress contour are presented and compared with different structures. A single cylinder uncooled test engine is used for the trade off studies. Both mullite and Si3N4 based ceramic piston crown succeeded in running over hundred hours under full load condition. PSZ upper liner is also succeed when suitable shrink fit is employed.
