The European Union currently pays great attention to the possibilities of the use of biofuels to power mobile machinery. The main reasons for the promotion of biofuels is the effort of Member States to reduce dependence on oil imports, efforts to reduce emissions from internal combustion engines and also efforts to support agriculture. The most common is currently using methyl rostliných oils because of their vlastbnosti closely resembles conventional diesel. Their production is energy intensive. Therefore, as a preferable alternative seems to be used directly vegetable oils. The use of vegetable oils is limited in particular viscosity and density. Therefore, in the paper evaluated the proportion of vegetable oil (rapeseed oil) in diesel in proportions 5.5 and 19.7%, to avoid engine damage. evaluated the emission components of carbon dioxide (CO2), carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulate matter (PM) and fuel consumption. A higher proportion of rapeseed oil in the fuel mainly reflects the increase in specific fuel consumption and carbon dioxide.
