Obtención del ciclo de conducción urbano para la ciudad de Riobamba en horas pico y no pico mediante la recolección de datos de los factores de operación y consumo energético obtenido por un dispositivo OBD II.

Abstract

The purpose of this investigation was to carry out the ideal driving cycle for Riobamba City by obtaining internal combustion engine operation factors to reproduce the second to second fuel consumption of light vehicles and identify the driving profile in the town. Conducted road tests gave a total of 146 in 10 vehicles. In obtaining data on routes, choosing different parameters to be monitored using the telephone software, "Torque Pro". With the use of the microcycle method, some 806 microcycles were obtained, from the total number of routes, considering the initial and final speed equal to zero, taking into account the idle times. Their cylinder capacity classified the number of vehicles. Filtration was carried out by the Minitab chipboard tool. The length of the driving cycle must be 800 seconds with a tolerance of 60 seconds. The result was four driving cycles for cars with different cylinder capacity. With a range of 9 to 17,5 L/100km instantaneous. It was expressed through urban driving cycles, that Riobamba City has a slow but aggressive driving, with a high rate of fuel consumption for its times at speeds below 20 km/h. The suggestion is to do more studies regarding fuel consumption concerning city traffic, and to take into account these interpretations to have new alternatives that control the energy expenditure of cars travelling in the city.
