Abstract
This paper objective is to study and analyse two different alternative green fuels (biofuels) obtained from rapeseed oil, a plant which grows in Ro-mania and jatropha oil that grows and is commonly used in Pakistan. The experimental test regarding the (on) engine performances and the level of pollutant emissions of the studied mono cylindrical diesel engine was conducted in the laboratory on Thermodynamics and Thermal Machines of the Faculty of Mechanics of Craiova. Various instruments were used to acquire pollutant emissions and corresponding data as well as the performances of the engine for each case. Nowadays, purposes for the diesel engines are a fuel product more efficient and a greater flexibility regarding the fuels with attention over the level of pollution.
Keywords: biodiesel, rapeseed oil, jatropha oil, emissions
