LPG 엔진 실린더 블록의 온도 분포 특성 해석을 위한 프로그램 개발

Development of a Program for Analyzing the Characteristics of the Temperature Distribution of the LPG Engine Cylinder Block

A computer program has been developed to predict the heat transfer characteristics and the temperature distribution in the cylinder block of a 4-cylinder, 4-stroke engine. The finete element method is employed to handle the complex geometries associated with the practical cylinder block. The hexahedron finite element is used for a mesh generation of three-dimensional domain. The present numerical procedure has been validated with the measured temperature at several locations of cylinder block. The heat transfer characteristics of engine cylinder block is systematically analyzed for various engine speeds and loading conditions.
