Abstract
The article presents the results of research on lubrication properties of rapeseed oil, methyl esters of rapeseed oil, as well as esters with goose fat. Rapeseed oil has a better lubrication properties in relation to methyl esters of rapeseed oil. Addition of goose fat to esters negatively affected their lubrication properties. The presented results confirm a relationship between the degree of unsaturated and lubricated properties. Among the tested compounds with oxygen groups (COOH, COOCH3, C = O), the oleic acid (with a COOH group) characterised the best lubricity. The fat goose, which contains the least amount of unsaturated fatty acid esters, proved to be ineffective addition lubricity between the factor lubricants analysis.
Highlights
The article presents the results of the tests of rapeseed oil lubricity, RME and RME with addition of goose fat
The smallest footprint area of cooperation was observed for samples lubricated with rapeseed oil
Addition of goose fat to methyl esters of rapeseed oil has resulted in an increase in mass loss of samples and the footprint area of cooperation and its equivalent diameter, when using this lubricant
Summary
The article presents the results of the tests of rapeseed oil lubricity, RME and RME with addition of goose fat. Selection of raw material for the production of biofuels depends mainly on the geographical region. This can be edible and nonedible vegetable oils, produced from rapeseed, soybean, sunflower seed, rice bran, tobacco, cotton, as well as animal fats and waste fats (Myczko, Golimowska 2011). In Poland, the main raw material for the production of biofuels is rapeseed oil (Szlachta 2002)
