Purpose. The technology makes it possible to predict the efficiency of using biodiesel fuel made from various types of plant raw materials, taking into account the influence of its physicochemical parameters on engine performance.
Specifications. Method for assessing efficiency: express assessment of the suitability of mixed biofuels, summarizing the results; method of obtaining initial data: chromatographic analysis; results processing: Microsoft Excel; permissible estimation error: 5%.
Application area. Agriculture, alternative bioenergy, organic technologies.
Advantages. The main advantage of the proposed technology is the ability to calculate the operational and technological indicators of the engine to predict and evaluate the efficiency of operation on various types of biodiesel fuel. A feature of this assessment is the use of chromatography methods and mathematical modeling in the Microsoft Excel software environment with subsequent generalization of the results according to developed recommendations without conducting experimental studies characterized by a significant consumption of material resources.
Technical and economic effect. The above scientific results have the following practical value: firstly, they allow us to evaluate the influence of the fatty acid composition of biodiesel fuel on one of the main indicators characterizing the efficiency of fuel use – the calorific value; secondly, they can serve as initial data for further research in developing new varieties of sunflower and rapeseed and determining the feasibility of using them as technical seeds for the production of biodiesel fuel; thirdly, they allow us to formulate a scientific hypothesis for further scientific research in the direction of developing new technologies for the production and use of alternative fuels – saturation with hydrogen in order to increase the calorific value of biodiesel fuel. A technology has been developed for a comprehensive assessment of the suitability of biofuels, which links engine operating parameters with the elemental composition of the fuel.
Description. A chromatographic analysis of the biodiesel fuel that is planned to be used is being carried out. The chromatography results are entered into the developed operating technical and economic model. Based on the results obtained after data processing, a complete assessment of the energy efficiency and environmental friendliness of a particular type of diesel engine with the possible use of this type of biodiesel fuel is given.
