The biofuel, a global approach

The paper present the work carried out by a research group from Technical University of Cluj-Napoca, Road Vehicles and Agricultural Machinery Department. According with the energetic demand of the society, new sources must be explored at the beginning of the new millennium. In this respect, the fuel obtained from vegetable oil represents an alternate option with flew benefits. Regarding the research carried a vision through the research target was promote. It consists in a sustainable energetic demand approach which must respond to the European conditions, in particularly, regarding the appropriate conditions from our country. In this respect, the work was developed in the following directions: center dot rapeseed oil crop in order to determine the must efficient biologic variety of it which respond to the soil conditions from our country; also the must appropriate cultivation technology was determine according with the soil demands; a special attention was focused in harvesting process due to the risk to loss an important production fraction; center dot rap seed oil production and the biofuel technology production from crude oil; this parts consist in a seeds press evaluation regarding the efficiency of the process in order to evaluate the oil quantity obtained in different press condition (with or without material heating); center dot tests results carried out in laboratory conditions in order to evaluate the energetic efficiency and the pollution eftect; an evaluation of the benefits and of the constraint regarding the rapeseed oil used as a fuel for Diesel engines.
