Comparação de desempenho e emissões de um motor gerador operando com diesel e blendas de biodiesel monitorado por sistemas de automação

Abstract

Fuels such as biodiesel are gaining a lot of popularity because it is an alternative fuel, cleaner and can be used directly in diesel engines without modification. It is about the evaluation, performance and emissions of a generator engine operating with diesel and biodiesel blends. Recording and monitoring electrical system parameters through industrial automation equipment. The experiment was conducted at the Automotive Technology Center (CTA) laboratory of the State University of West Paraná (UNIOESTE), Cascavel – Paraná. The energy generated, the specific consumption, the energy efficiency and the emissions generated by the generator set were evaluated. The treatments used were type A petroleum diesel and six canola biodiesel blends (B005, B010, B015, B020, B050 and B100). The loads applied to the generator engine were of the resistive type of 1.0 1.5, 4.5 and 6.0 kW for each type of fuel. The generated energy kept increasing and stable as the load increased. The best CE result was with diesel, followed by B010 and B020 both for the 4.5 kW load. CO gas emissions are reduced while CO2 emissions increase with application of higher loads. Pure biodiesel (B100) tends to present better EE than the binary mixtures used when inserted at a load of 6.0kW. The B100 showed increasing EE for resistive loads of 1.0, 1.5, 4.5, 6.0 kW. The results obtained demonstrate that the blends of rapeseed biodiesel with conventional diesel are one of the possible viable solutions for the partial replacement of mineral diesel.
