Abstract

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.

Highlights

Petroleum which a mixture of carbohydrates, carboxylic acids, thioalcohols, heterocyclic nitric compounds, phenols, thiophen derivatives, resins and metalorganic compounds undergoes constant technological modifications for purification and separation of chemical compounds and their refinement [1]
Literature provides an array of fuel consumption tests, whose authors report an increase in fuel demand when self-ignition engines are fueled with mixtures of diesel oil and fatty acid methyl esters. [12, 13, 14, 15]
The results indicate too small content of fatty acid methyl esters in diesel oil

Summary

Introduction

Petroleum which a mixture of carbohydrates, carboxylic acids, thioalcohols, heterocyclic nitric compounds, phenols, thiophen derivatives, resins and metalorganic compounds undergoes constant technological modifications for purification and separation of chemical compounds and their refinement [1]. Mixtures of pure fatty acid methyl esters FAME with a diesel referred to as biodiesel are supposed to provide the engine with good conditions of operation. Literature provides an array of fuel consumption tests, whose authors report an increase in fuel demand when self-ignition engines are fueled with mixtures of diesel oil and fatty acid methyl esters. Application of fatty acid methyl esters in combustion engines causes reduction in toxic pollution emissions, such as carbon oxides, hydrocarbons and solid particles [17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28]. Literature provides different methods for transport system functioning assessment [30, 31, 32]
