Resumo

The brazilian energy matrix has undergone a review of its policy when it comes to fossil fuels, using the 70's with the oil crisis, imposing an energy saving and reduction of dependence derived from imported oil. Since then measures have been taken, such as increased domestic production and increased use of natural gas in the brazilian energy matrix. The vehicular natural gas (VNG) is able to reduce significantly the emission of pollutants, reducing public spending on health and diesel oil import costs. The biodiesel, renewable energy source contrary to diesel derived from fossil, can reduce emissions by 78% carbon dioxide and 90% smoke propriciando reduction of sulfur oxide. This paper will be the analysis of exhaust gases from a diesel engine MWM 4:07 TEC based on electronic common-rail injection system and a wide range of engine vehicular using this model such as GM truck S10; Minibus Volare and Nissan Frontier. In the production of biodiesel in the internal combustion engine testing for gas analysis, the percentages mixtures are equivalent to B7 (7%), B20(20%) and B50 (50%) biodiesel added to the diesel oil, as well as pure B100 biodiesel in mixtures assays. In both tests, the VNG or biodiesel, the use of such fuels predominant role in reducing pollution in the environment. Currently, issues related to the environment and the protections of consumer economic power are matters of concern for government agencies and society in the search for energy alternatives in environmental economic improvements.
