Abstract:

The environmental advantages of biofuels cannot only evaluate the final production of pollutants resulting from the combustion of biofuels in the vehicle, but it is necessary to take into account the entire life cycle of fuels including the initial phase of production of raw materials through production to finally the fuel burning vehicle and how it affects the vehicle mechanisms. The Article describes the possibilities of powering diesel engines based on vegetable oils (RME, rapeseed oil) as an alternative to standard diesel fuel. It deals with the properties of biofuels and their potential use in the internal combustion engines by the structural adjustment of the fuel system or the combustion chamber. It also highlights the potential negative impacts of vegetable oils on the machine’s operability and the possibility of reducing the negative effects. The article is based on laboratory analysis of tribotechnical diagnostics. They describe the current state of oil, its primary and secondary pollution and wear of the machine. The important method is ferrography to which the main emphasis is focused. The experimental section analyzes the impact of biofuels on the quality of oil used to fill diesel engines, and establishes an optimal oil change interval. For minimization the negative effects of biofuels is tribotechnical diagnosis necessary part of fuels quality evaluation. Key words: rapeseed oil, RME, engine lubrication oil, construction change, tribotechnical diagnostic.INTRODUCTION
