The Concept of the Tractor Powered by Biodiesel and Biogas

Agriculture farms, especially animal farms consume a lot of energy. They also have big potential to produce energy by themselves. The production of biogas and its efficient utilisation could meet the need for fuel and energy. The production of biogas on a farm and its utilisation as a fuel could improve its energetic balance and safe some money. The paper describes the possible way of utilisation of upgraded manure biogas as a fuel for compression ignition engine, which is adopted for dual fuelling. The engine is going to be fuelled with vegetable oil ester and biogas produced directly on animal farm. Some calculation of fuel consumption of both fuels and analysis of possible changes of combustion process for dual fuelling mode are presented. There is also described the concept of adaptation of CI engine for agriculture tractor to dual fuelling with vegetable oil ester and biogas.
