Sažetak
Vegetable oils are a very important component in human and animal nutrition. Furthermore, they represent potential fuels for engines as well. These fuels named as biofuels are renewable energy sources which must gradually replace today’s conventional fuels made from crude oil. The higher energy demands in production and problems which arise during their combustion are the main disadvantages of
biofuels. Vegetable oils made from rape seeds belong to the most used biofuels for diesel engines in the Czech Republic. The article describes use of rapeseed oil, methyl esters of rapeseed oil (RME) and their mixture with diesel fuel (B30) in diesel engines, their ecological benefits in combustion and necessary modification of some elements in engines. Data used for evaluation were obtained from measurements
in the vehicle laboratory. The results were compared with the diesel fuel. As results show, evaluated biofuels have a positive impact on exhaust emissions of engines but at higher consumption.
