THE STUDY OF THE CONSTRUCTION HEAT TRANSFER MODEL OF DIESEL ENGINES USING DUAL FUEL DIESEL-ETHANOL

Abstract

The research, development and application of alternative fuels are general trend in many countries around the world to reduce dependence on fossil fuels, energy security as well as reducing environmental impact particularly the greenhouse gases. In particular, ethanol is considered as one of the potential fuel used for diesel engines. There have been many projects in the world and Vietnam to study the construction of the heat transfer model of diesel engines used dual-fuel such as diesel LPG, diesel-CNG. However, no study to model heat transfer of diesel engine used dual fuel diesel-ethanol has different physical and chemical characteristics which are quite different with those of the above-mentioned ones. This paper presents the study of the construction heat transfer model of diesel engines using dual fuel diesel-ethanol by Matlab simulink software. The results show that the pressure variation in the engine cylinder between the model and the experiment is accurate, so model can be used to build a combustion model of diessel engines using dual fuel diesel-ethanol.
