Análisis del estilo de conducción de un vehículo con motor MPI mediante el ciclo de emisiones reales RDE para determinar su influencia en el consumo de combustible en la ciudad de Quito-Ecuador

Abstract

In the city of Quito, Ecuador, the growth of the automotive fleet and high fuel prices have raised increasing concerns about reducing fuel consumption and decreasing associated emissions. While there are various perspectives to address this concern, such as air filtering, fuel octane rating, engine characteristics, etc., one of the most influential factors in high fuel consumption is driving style. Driving style, characterized by factors such as frequent use of brakes and accelerator, untimely gear shifts, and extended idling time, has been identified as a determining factor in fuel consumption. In this project, a comprehensive analysis is conducted on the characteristics that are correlated with fuel consumption, focusing on their influence on driving style, whether it is normal or aggressive. The results reveal that engine revolutions, speed, throttle position, and absolute manifold pressure are critical aspects that converge in their impact on average fuel consumption, along with other factors that vary according to driver behavior. These variables show a strong relationship with driving style and its influence on fuel consumption efficiency. Additionally, the development of a machine learning model is proposed to classify driving style based on road conditions according to the RDE cycle, and its relationship with fuel consumption in each stage of the cycle: urban, rural, and highway. The obtained results indicate that a more aggressive driving style is associated with an increase in fuel consumption.
