Abstract
The growing concern with the preservation of the environment has affected several areas of engineering sciences. The study and development of internal combustion engines, which are among the equipment considered to be major pollutant emitters, are also being greatly influenced by this concern. This causes a need to decrease the use of fossil fuels, which can be observed by the number of studies and research relating internal combustion engines and renewable energy sources. One of the energy sources that has been widely studied and analyzed as a viable alternative to the use of fossil fuels is biogas. Although recent, research involving the use of biogas as an engine fuel has grown considerably in the last 10 years. To analyze this scenario and thus conduct a literature review of the subject, searches were conducted in the Scopus database using keywords and appropriate filters. Articles not related or with little adherence to the subject were excluded from the review. The results were articles focused both on the composition of the biogas, which depends on the production process and may have effects on the combustion process, and on the efficiency of the use of biogas as a single or dual source of fuel for the engine. It was possible to verify, from the articles provided, good performance of the engines tested using biogas with different compositions, as well as analyses comparing emissions of pollutant gases. In general, these results are satisfactory, but leave room for further analysis under different conditions. Another parameter that is a point of concern are the hydrogen sulfide emissions, which, besides being highly toxic, can compromise the integrity of the engine components in the long term. Thus, the use of biogas as a fuel for internal combustion engines is proving to be a viable alternative and should continue to occupy more and more space in academic and industrial circles.
