This work shows the results of the tests carried out on the Volkswagen 1.9 SDI engine in the Armfield CM12 stationary test bench and the Launch X-431 pro scanner performed in the diesel engine laboratory of the Department of Agricultural Mechanical Engineering (DIMA) of Chapingo Autonomous University (UACh). The methodology of SAE J1995 and ISO 8178 Standards were used to obtain the values of HC, NOx, CO, CO2 and O2. In addition, the variation of lambda &#955; index was obtained. The characteristics of each component were constructed based on the load (power) and the lambda index. The concentrations were 30.25 g kW-1h-1 for HC + NOx and 0.47 g kW-1h-1 for CO which is below the established limits.]]></p></abstract>

En el presente trabajo se muestran los resultados de las pruebas realizadas al motor Volkswagen 1.9 SDI en el banco de pruebas estacionario Armfield CM12 y el escáner Launch X-431 pro realizadas en el laboratorio de motores diésel del Departamento de Ingeniería Mecánica Agrícola (DIMA) de la Universidad Autónoma Chapingo (UACh). Se utilizó la metodología de las Normas SAE J1995 e ISO 8178 para obtener los valores de los componentes del escape. Se construyeron las características de cada componente en función de la carga (potencia) y del índice lambda. Las concentraciones de HC + NOx fueron de 30.25 g kW-1h-1 y del CO de 0.47 g kW-1 h-1 está por debajo de los límites establecidos.]]></p></abstract>
