ABSTRACT
Fuels used for diesel engines besides their main function of energy supply act as a lubricant. In this context the most important task is lubrication of precision pairs injection equipment. In this paper lubricating properties of rapeseed oil esters and camelina esters have been compared. Dependency of the electrical resistance and friction coefficient of the lubrication surface using different types of fuel was analyzed. It was stated, that the highest electrical resistance occurs when lubrication is done with diesel fuel, whereas the friction coefficient is the lowest and it occurs at lubrication with camellia esters.
