Evaluación de la economía de combustible en vehículo a gasolina en condiciones reales de tráfico bajo la aplicación del aire acondicionado en los cantones de Celica y Latacunga

Abstract

In this research work, it was analyzed the fuel consumption in actual traffic conditions to compare with the use of air conditioning in the cantons of Celica and Latacunga. According to the Association of Automotive Companies of Ecuador (AEADE), the vehicle fleet has increased considerably, with the Kía Río and Chevrolet Sail brands part of the best-selling vehicles annually. These vehicles share the same characteristic of the air conditioning system in a large number of their sold units. The study was carried out on the main roads of each parish with 11.5km per route. The routes share similarities with the EPA FTP-75 (City Cycle) and EPA HWFET (Highway Cycle) driving cycles for the cantons of Latacunga and Celica respectively, using extra and super gasoline as fuel. The OBDII Vgate iCar Bluetooth scanner and the OBD FUSION mobile application were used to gather information, which was selected based on the needs and characteristics of the study to evaluate torque, power, fuel consumption, and specific consumption. The obtained results in Latacunga canton showed increases in fuel consumption of 21% RL1 and 36% RL2 and 19% SL1 and 24% SL2, while in the Celica canton the increases were from 7% RC1 to 9% RC2 and 4% SC1 and 6% SC2. As well as higher torque increases when the A/C is active. The tests showed that maximum fuel consumption occurs in the Latacunga canton with and without the use of air conditioning with super fuel and in the Celica canton with extra fuel. The use of payment software is recommended to obtain the greatest amount of data analysis functions.
