Análisis del consumo de combustible del motor S-TEC II 16V del vehículo Chevrolet Sail al variar el número de agujeros de las toberas de los inyectores aplicando la modalidad de conducción Ecodriving en el Distrito Metropolitano de Quito

Abstract

This study focuses on addressing the problem of high fuel consumption in the transport sector in Ecuador, which represents 48.9% of total energy consumption, with 80.1% coming from fossil fuels. The study uses Extra petrol and proceeds to the calculation and comparison of fuel consumption between 4- and 6hole injectors, using an Eco-driving style in the city of Quito. Several test drives were carried out on an established route using a Sail vehicle. In addition, factors such as engine volumetric efficiency, idling times, vehicle accelerations, traffic conditions, among others, were considered for the fuel consumption analysis and comparison. The results indicate that the 6-hole injectors have better fuel atomisation, resulting in more efficient combustion. Applying Eco-driving, the ideal consumption with the 6-hole injectors and 100% volumetric efficiency is 0.7534 gallons, while the actual consumption with the same injectors and actual efficiency is 0.4957 gallons, representing a saving of 6.02% compared to the actual consumption with the 4-hole injectors.
