Engine and road tests of blends of biodiesel and diesel fuel

Abstract

The utilization of alternative fuels in transport is very important due to dependence on petroleum, increaseasing in number of vehicles and as consequence high CO2 emission. The investigations of biodiesel as an alternative fuels include raw materials, production, quality (pure or in mixture with diesel), engine and vehicle tests and determining compliance with sustainability criteria. In this paper, the investigations were performed with the biodiesel prepared from damaged sunflower seed and used cooking oils using the latest technology for the purification of biodiesel from methanol based on ion exchange principle. The main target was to examine the possibility of utilisation of different biodiesel and diesel blends in Compression Ignition (CI) engines and their influence on engine power, torque, fuel consumption and exhaust emission. The results of standard and non-standard investigations and engine and vehicle tests of biodiesel and diesel blends are presented.
