Study of the Environmental and Technical Performance of a Diesel Engine with the Alternative Use of Biofuel Obtained from the Reutilization of Vegetable Oil

摘要

The aim of this work is to provide an environmental assessment of a diesel engine by analyzing the emissions of CO, CO2and NOxthat result from the combustion process, as well as analyzing technical performance related to consumption and the development of power and torque in a laboratory test rig. Biodiesel fuel was produced from vegetable cooking oil. The intention of this work is to evaluate the best method for the production of biodiesel in reference to an analysis of the peculiar features of this process of procurement and control of the physical environmental variables that may result in better performance of the engine under the conditions of the use of biodiesel blends with commercial diesel. The use of cooking oil as a raw material for biodiesel production has proven to be of significant value as compared to other raw material choices of various origins such as the oilseed crop since cooking oil is available in large quantities without any defined application. Gains related to the reduction of emissions of toxic gases resulting from combustion processes were remarkable, mainly in terms of the large reduction of CO and CO2 emissions.
