Advantages of the use of biodiesel B10 (Ricinus communis) on Diesel fossil in the protection of the environment

Abstract:

The presence of soot in the environment has been considerably increasing lately according to the World Health Organization. One of the causes of this issue is due to the diesel engines. The study focuses on evaluating the presence of soot on an engine by using fuels such as Ricinus communis biodiesel and fossil diesel. The experiment was carried out using a diesel engine test bench Mazda BT50 with CRDi system. In order to run the tests, a BrainBee opacimeter was used. The opacimeter was connected into a probe, which is placed at the end of the car exhaust pipe. The experiment consists of testing the engine for several accelerations such as 1200, 1500, 2000, 2500, 3000 revolutions per minute (RPM) using Ricinus communis biodiesel and fossil diesel. Once all the accelerations are completed, the opacity difference was obtained to make a comparative analysis from the highest to the lowest opacity, resulting as the average percentage of opacity, which is the result that should be followed according to the established norms. It was observed 80% of reduction in diesel engine opacity with the use of Ricinus communis biodiesel comparing to fossil diesel.
