Study on the relationship between design parameters and volume of diesel engine based on orthogonal experiment design

Abstract

In this paper, a parametric experiment model of V-8 diesel engine is developed. The angle of V-shape, cylinder-to-cylinder spacing, and connecting rod length are selected as research factors and their influences on the engine's volume are studied by the orthogonal experiment. In each experiment a new engine model is built by changing these factors' values and the volume of the new model is calculated. Through analysis of variance, the significant relations between diesel engine volume and factors are given, which provide the criteria for the selection of the design parameters.
