In the literature, the quantities describing the physicochemical parameters describing the combustion processes are: calorific value, cetane number LC, auto-ignition temperature, solidification point, viscosity and surface tension, and heat of vaporization. This article shows that another parameter influencing the combustion process in a thermodynamic engine, which is an engine, is also influenced by chemical bonds between atoms. Selected 11 alcohols differing in the number of chemical bonds between carbon atoms (...

Nowadays, in the literature we come across the notion that selected physico-chemical parameters have an influence on diesel engine operation and are included in the European standard PN- 590. Fuels meeting the standard for diesel engine are complex substances, which do not consist of simple hydrocarbons, but very complex, extended aromatic hydrocarbons. This paper presents proposals for the use of simple chemical compounds such as alcohols as diesel engine fuels. It has been demonstrated that selected alcohols can...
