Graph Theory and Matrix Method for Development and Design of Combustion Engine

Abstract

The idea upon which any methodology development is pillared leads to real time decisions if simulation and assessment is as per the standard codes set by standard organizations. More near is the system with standard system more it is appropriate for operation. In the present work system under consideration is internal combustion engine. Fuel cost is one of the most important parameter in life cycle analysis of the internal combustion engines. Therefore, efficiency analysis becomes the prior most parameter to be analysed. In the present work a methodology is developed for efficiency analysis of an internal combustion engine. Parameters and factors affecting engine performance are identified and different sections are developed as per the parameters. Value of permanent function for present case is 5992 and for the real time case is 5638. Value of relative quality index comes out to be 37.51 %. From graph theory and matrix method it came out that with decrease in compression ratio, efficiency is decreased from 39.51% to 37.51%. Keywords: Efficiency, IC engine, Index, Emission
