Evaluación del comportamiento energético y ambiental de un motor de encendido provocado bajo diferentes tipos de gasolinas

Abstract

Because of the impact of the transport in the energetic efficiency of the industry, this work studies the torque, power and emissions affectation due to change the fuel by using the kinds of gasoline commercialized in the Ecuadorian Sierra as are the Extra, Super and Super G-Prix. In order to perform this analysis, a 2018 Chevrolet Tracker model SUV type vehicle is used, this model is similar to the ones that actually are the most popular, thus the better or worse efficiency causes an direct impact in the economy, to the production chain and the environment. In addition, in general, these kinds of gasolines are used for the most of vehicles in this country. The vehicle incorporates an atmospheric direct injection internal combustion engine. In the tests it is used a rolls chassis dynamometer. It is applied the IM240 road test to analyze the gasoline consume and study the emissions generated by the vehicle; and the torque and power test to observe the vehicle performance. Three repetitions are done for every test using the three kinds of gasoline. Later, a statistical analysis is done with the collected data. The results is possible to conclude that in general the best result is achieved by the Super gasoline and that the Super G-Prix gasoline offers similar results in terms of energetic efficiency and environmental impact measured by the value of 96,6kW of power in contrast with the 92,4kW obtained when the Extra gasoline is used. When the IM240 road dynamic test is applied, the emissions of CO are around 1g/km by using the Super G-Prix gasoline in contrast with the 1,8g/km obtained when the Extra gasoline is used.
