Emission Control Evolution of the 2.0 L Gasohol/Ethanol Engines in Brasil 921493

In May 1986 with the officialization of the PROCONVE - Program for Controlling the Air Pollution by Automotive Vehicles, by the Resolution N°.018/86 issued by the Brazilian Environmental Council - CONAMA (Appendix I), the local auto industry was called to use its creativity, financial and technological capacity, and its best strategic planning to effectively implement this emission control program.
At that time, Brazil already had specific scenarios related to fuels used by passenger cars such as the large usage of Hydrated Ethanol - Appendix II, which will be called E100 from now on, and the usage of Gasohol - Appendix III, a blend of gasoline with 22 percent anhydrous ethanol, which will be called E22. This blend, in several locations still had a certain amount of lead, which was completely eliminated only at the beginning of 1992. These scenarios forced Brazil to develop its own emission control tecnology to meet the emission standards, once no other country in the world had used such fuels.
This paper will present the steps taken by the Product Engineering of General Motors do Brasil to implement the emission control on its Family II - 2.0 L E100/E22 engines from 1987 up to 1992, as well as the results achieved.
All data shown in this paper are real and can be of great value to anyone interested in stablishing an emission control program similarly to Brazil, as well as those interested in emissions from alternative fuels such as Ethanol (E100) and Gasoline-Ethanol blend (E22).
