Análise da viabilidade técnica do uso de biodiesel e gás natural em motores do ciclo diesel operando no modo dual.

Abstract

The internal combustion engines are a major cause of rising levels of pollution of the planet, thus facing such situation and where life without energy generation would become complicated, the demand for alternative energy sources that minimize such issues is a constant in our day-to-day. In diesel engines, operations with diesel and natural gas are being tested to reduce emissions of pollutants to the environment, such as carbon monoxide (CO), carbon dioxide (CO2) and sulfur dioxide (SO2). Thus, this work aims to study experimentally these emissions and other gases from an internal combustion engine diesel cycle, operating with biodiesel blends and natural gas, and compare the results with data collected with the engine running with diesel. The thermal system is composed of an experimental internal combustion engine coupled to an electric generator, instrumented with sensors for temperature, pressure, air flow meters, diesel and natural gas probe and gas absorption system consisting of a power bank load and its control system. For energy analysis engine efficiency values were obtained through the combustion gas analyzer. In the course of the work, there was a considerable reduction of greenhouse gas emissions into the atmosphere and with respect to efficiency and fuel consumption, the changes were acceptable.
