Abstract
The atmosphere is in great danger and consequently the entire living environment is placed at risk. A serious control and radical measures are needed in order to create a secure future for the atmosphere. Biodiesel represents an important solution to the numerous and urgent, national and international environmental problem, concerning air pollution. By burning more clean and less polluting fuels can significantly reduce the polluting emissions.
The experimental research that has been carried out had in view the measurement of the polluting agents and the assessment of the level of polluting emissions (smoke; CO2; CO and CmHn), in the case of the D-2402.000 engine supplied with different types of fuel based on sunflower oil (virgin and used) as compared to the operation of the same engine supplied with diesel fuel.
The experimental research was performed on a stand which was equipped with a D2402.000 engine, hydraulic brake, sensors, transducers and a quick system of data acquisition, in the Biofuel Lab of the Automotive and Agricultural Machinery Department, Technical University of Cluj-Napoca. The measurement of the polluting agents was performed using the diagnosis platform - SMP 4000.
