Aplicación de la norma NTE INEN 2207: 2002 en la medición de emisiones de gases en vehículos a diesel en la Universidad Técnica de Ambato campus Huachi

Abstract

The objective of this technical project is to determine the gas emissions produced by diesel vehicles circulating at the Technical University of Ambato Campus Huachi, using the exhaust gas analyser of diesel engines MDO 2 LON, previously chosen among several teams and being the optimal for the development of this work, the percentage of opacity was specifically determined, this term is understood to mean the value of the decrease in the magnitude of visible light generated by an element when passing through the light, in addition the oil temperature, the RPM, and the value k were determined, being this an equivalent of the percentage of opacity with different units such as the meters at least one , in order to be able to determine whether they comply with the limits set out in NTE INEN 2207:2002, which are subdivided into two groups of vehicles, those of 1999 and earlier, and those of 2000 and later, Taking into account that the specific standard for motor vehicles does not exclude any vehicle, 62 vans, 3 trucks and 6 buses were submitted for analysis. A global analysis of the entire vehicle fleet was carried out, determining the type of vehicle that most pollutes the environment with 79 percent opacity percentage is the bus brand Chevrolet of the year 2008, In addition, with the help of the Pearson Correlation, an individual analysis was carried out by brand and type of vehicle, obtaining in all cases a negative trend line , that is, as the value of one variable decreases, the other variable increases, this is presented below in graphs and tables.
