Application and Research of TRIZ Theory in Controlling Compression Ratio of Hydraulic Free Piston Engine

Abstract

Abstract: Based on TRIZ theory, a new kind of Hydraulic Free Piston Engine (HFPE) is designed and innovated to solve the problem of uncontrollable compression ratio. Firstly, the factors affecting the compression ratio control are obtained by causal chain analysis; the existing problems of the system are found by functional analysis, and the functional model is cut. Then the design scheme of Hydraulic Free Piston Engine (HFPE) is derived by applying substance-field, technical contradiction, and SIMS method. It is found that this Hydraulic Free Piston Engine (HFPE) has the advantages of high control accuracy and simple structure.

Key words: TRIZ, Hydraulic Free Piston Engine (HFPE), Functional analysis, Substance-field analysis, Technical contradictions
