Aanálisis del consumo instantáneo de combustible mediante señales PID´s en vehículos de categoría M1, considerando la influencia de sistemas auxiliares y condiciones dinámicas, a través de un ciclo RDE en el Distrito Metropolitano de Quito

Abstract

In the Metropolitan District of Quito, various RDE driving tests were carried out with the aim of quantifying the percentage fluctuation in instantaneous fuel consumption by varying certain dynamic influences such as tire pressures and auxiliary vehicle systems such as the use of air conditioning. In the standard test, total consumption was 7.26 L when driving with a tire pressure of 35 PSI and the air conditioning turned off. Subsequently, using half of the air conditioning resulted in a 17% increase, and using the air conditioning at maximum speed resulted in a 19.7% increase. With regard to the variation in tire pressure, driving with a tire pressure of 33 PSI resulted in an increase of 4.4%, while driving with a tire pressure of 37 PSI resulted in a negligible increase of 0.27%. The use of air conditioning can influence consumption, decreasing it by 3% or increasing it by up to 57% depending on usage and the area of circulation. Tyre inflation pressure can vary consumption, decreasing it by 5% or increasing it by up to 32% depending on the area of circulation. And opening the windows can vary fuel consumption by decreasing it by 10% or increasing it by up to 35%, depending on how much the windows are opened and the area of circulation.

Using the Multiple Linear Regression Mathematical Model, in which the following variables were used: TPS, IAT, Altitude and Engine Power, a value of 𝑅2 0.656.
