Summary:

It is widely believed that the additional fuel components of spark ignition engines are mainly light alcohols. In order to change this state of affairs, it was assumed that it is also possible to create ternary fuel mixtures with the addition of heavy alcohols. The hypothesis was adopted that such a fuel mixture may contain any proportion of individual components. The truth of the hypothesis was demonstrated by preparing a number of mixtures of isooctane with ethyl and butyl alcohols (n-butanol), which were homogeneous and did not stratify even after prolonged storage.An in-depth literature study was conducted, which shows that such mixtures, however known, are described in the literature extremely modestly, and in addition the results of individual studies are divergent, which results, among others, from methodological shortcomings in the study of fuel compositions.The research methodology adopted in this work is based on the assumption that the composition of ternary fuels should be consistent with the relevant experiment plan, while the assessment of the impact of the composition on engine parameters should be made by operating a multi-equation mathematical model, and each of these equations, as a sub-model, must be statistically verified.The boundary conditions of the mathematical model were determined based on research on a real object. The fuel mixtures used in the exploratory tests were selected based on a simple experiment plan. Forcing factors in this plan were volume shares of fuel components, id est isooctane, ethanol and butanol. In total, eleven mixtures were prepared and tested on the basis of which it was possible to forecast many engine operating parameters centered around thermal efficiency expressed in unit fuel consumption in relation to exhaust gas emission parameters with the indication of the most favorable values. The response surface of the object (in system terms) was obtained using the ANOVA method.Adopting appropriate compromises, it can be pointed out that the most advantageous mixture in terms of all the analyzed parameters will be the one which will contain about 80% v / v of isooctane supplemented with ethanol and butanol in a wide proportion
