“…Parameter values have been collected from many papers of other authors [1,7,9,13,[16][17][18][19][20][21][22][23][24] and own research [4,6]. At the same time, it should be remembered that the main criterion for assessing individual oils is their performance in the context of the most important operating parameters, which should be the basis for their classification [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41].…”

Vegetable oils are considered to be an alternative and environmentally friendly resource of lubricants. Suitable for almost all industrial applications. They are obtained from natural raw materials, which are renewable and non-toxic to humans, living organisms, and the environment. Chemically, green oils are triacylglycerols with varying fatty acids compositions depending on the plant or seed, the crop, the growing conditions and the season, etc. The conducted research concerning matching the proper of type of vegetable oil to lubrication of the engine. The main objectives of engine oil have been drawn to the attention. To project of assessment has selected four roles of engine oil: lubrication, cooling, corrosion protection, and others (including oxidative stability, ash content, saponification value, and foam property). Each objective is described by a couple of detailed parameters of lubricants (for example viscosity index, coefficient of friction, wear scar diameter, pour point, cloud point, melting point, smoke point, flash point, iodine value, thermal conductivity, specific heat capacity, density, water content, acid number, anti-corrosion properties, etc.). In the evaluation process, AHP (Analytic Hierarchy Process) methods were used to determine the weights of individual criteria. Everything creates multiple criteria assessment of green oil. As a result of the multi-criteria assessment, most high scores have soybean oil, linseed oil, cottonseed oil, and olive.

“…Distribution of the solid particle sizes and their number, were determined with the use of an electronic particle counter. Although literature provides results of research on similar units, the authors of this study find it advisable to present results of tests of selected performance parameters of a combustion engine [38,39,40].…”

Ecological approach to transport including the fuel which is used in combustion engines involves a necessity of alternative solution application. The study shows test result analysis of the amount of exhaust gases affecting natural environment. The tests were performed for a 81W self-ignition engine with a direct fuel injection. The experiment was conducted for a fuel mixture containing 70% of diesel oil 30% of fatty acid methyl esters. The results regarding concentration of fuel components obtained for the analyzed mixture were compared with the results obtained for a diesel oil without fatty acid methyl esters. Based on the analysis, it can be said that 30% additive of fatty acid methyl esters to diesel oil is not enough to decrease the amount of harmful substance emission to the atmosphere by a power unit.

Mobile stage construction is a huge challenge for designers due to a very wide range of variable factors influencing it, such as wind or temperature, the value of which in this case depends on the geographical location. An inherent element of the impact of these factors are the accompanying different, both constant and variable loads. Detailed identification of these loads is as important as the analysis of the dynamic properties of the structure. The more so as the analyzed structure appears in two configurations, first as a semitrailer, and then as a stage.
