Estudio termográfico en un motor de combustión interna de gasolina g4nb en DM. de Quito utilizando filtros de aire estandár y de alto flujo y su influencia en las emisiones contaminantes (hc, co) al aplicar el procedimiento de medición de la norma NTE INEN 2203:2000

Abstract

The study carried out a comparative analysis on the emission and temperature values of a gasoline engine by modifying the air filter in a gasoline vehicle. The methodology of this study was carried out with the help of the Fortic 348 Thermographic camera and the KANE EGA 5 gas analyzer. A standard air filter and a high flow air filter were used. The tests performed were based on NTE INEN 2 203:2000 "ENVIRONMENTAL MANAGEMENT. AIR. MOTOR VEHICLES. DETERMINATION OF THE CONCENTRATION OF EXHAUST EMISSIONS IN MINIMUM RUNNING CONDITIONS OR RALENTI.STATIC TEST", simultaneously thermographic data was taken in the throttle body by means of the thermography camera. For the analysis of the collected data, a 2k factorial design (k=2) was implemented, with the factors being filter and engine speed. It has 16 trials. The results of the statistical analysis show that the high flow filter reduces HC emissions by 10.625 ppm in both engine speeds, CO with a reduction of 0.092 units and temperature by 3 units at cruising speed.
