Effective Parameters of a Compression-Ignition Engine Powered by a Mixture Consisting of Ethyl-Tetra-Butyl Ether and Diesel Fuel

Abstract

The present article presents the results of analytical research on the possibility of using a mixture consisting of diesel oil and ethyl-tertiary-butyl ether in different percentages of EETB to power compression-ignition engines. The calculations were carried out for a four-stroke diesel engine intended for use as a power generator, among other things. In order to illustrate and verify the correctness of the calculations, a mathematical model was built that confirmed the correctness of the calculations. The calculations focused on a thorough analysis of the elemental composition (content of individual elements) of the fuel and, in particular, the carbon content in the fuel. A calculation algorithm was applied for mixing diesel fuel with ethyl-tertiary butyl ether in a share of EETB 5% + 95% ON, 10% EETB + 90% ON, 20% EETB ++80% ON, 30% EETB + 70% ON, 40% EETB + 60% ON. In this study, it determined the parameters of the working medium, the parameters of the environment and residual gases, and the processes (charge filling, compression, combustion, expansion) and effective parameters of the engine. The calculations used in this study led to heat balance, and a summary of the obtained results and their comparison with diesel oil are also described in this study. The results show the feasibility of using a mixture of ethyl-tertiary-butyl ether as a fuel in diesel engines. The results are very similar to those for 100% diesel. The results of our calculations confirming the possibility of using ether for fuel and thus maintaining similar engine operating parameters.
