Implementación de un sistema de tratamiento de gases de escape mediante inyección de aire en un vehículo a gasolina.

Abstract

The present work deals with the Implementation of an Exhaust Gas Treatment System through the Air Injection in a Gasoline Powered Vehicle to contribute to the air quality improvement because of the excessive contamination levels from the automotives which do not have emission control. The purpose of this thesis project is implementing an Exhaust Gas Treatment System through Air Injection in an Otto cycle motor, which permits to present a practical solution for the environmental control causing with this oxidation and reduction reactions in the exhaust gases sent to the environment by these vehicles. The gas treatments system implementation results were taken from a vehicle which does not have any emission control (Chevrolet Condor 1979) resulting in the following data: HC of 2771 ppm to 457 ppm, CO of 10.67% to 1.66%, O2 of 3.69% to 0.02% which in general represent a 73% system efficiency over the contamination values originally obtained in the vehicle without any emission control. These results permit that the vehicle be suitable to approve the requirements proposed by the CORPAIRE as related to contaminant gas level produced by this vehicle. Additionally it presents an improvement in the levels required by the INEN in the technical norm NTE INEN 2 204 for a vehicle with such characteristics. As a conclusion, the implemented gas treatment system was capable of considerably reducing the produced noxious gas level with the possibility of being improved even more through the optimization of the air injection in the exhaust.
