The introduction of Flexfuel technology in Brazil in 2003 brought an unquestionable advantage to reduce the emissions of greenhouse gases in automobiles when used with ethanol. Furthermore, the research to increase the efficiency in the use of renewable energy is crucial for the sustainability of the automotive industry. Among the feasible technologies for achieving this goal, the Direct Injection Spark-Ignited engine (hereinafter referred to as a DISI engine) and the turbocharger are the most promising in short and middle terms. The combined use of Direct Injection and turbocharger on an engine can promote the downsizing. Both technologies are closer to the Brazilian reality and the Turbocharged DISI engine can even more be improved when used with the biofuel ethanol through its inherent thermodynamics advantages.
