Evaluación de la eficiencia energética de vehículos pesados en el ciclo // Evaluation of the heavy duty trucks energy efficiency in the modified drive cycle.
Abstract
Resumen
En este trabajo, se presenta la reformulación de un ciclo teórico que consta de los elementos
básicos de un ciclo de viaje real con condiciones prefijadas de movimiento y operación. En la
modificación se tomaron en cuenta los siguientes elementos: frecuencia de rotación mínima en
movimiento estable; eficiencia de la transmisión variable con la velocidad, la carga y la marcha
conectada; un nuevo criterio de frecuencia de rotación del motor para el cambio de marchas; el
frenado con el motor embragado y; nuevas expresiones de cuantificación del consumo de
combustible. Obteniéndose nuevos modelos matemáticos para la determinación de los indicadores
del consumo de combustible de vehículos pesados de transmisión mecánica. Se presenta además,
un indicador “Coeficiente de Efectividad del Trabajo del Automóvil” (CETA) que describe la
eficiencia energética durante el periodo de impulso, expresada a través del grado de
aprovechamiento de la energía del automóvil para llevar hasta determinada velocidad la masa de la
carga útil.
Palabras claves:
ciclo de viaje, consumo de combustible, evaluación vehicular, modelos matemáticos.

Abstract
In this paper, the new formulation of a theoretical drive cycle is presented. It is integrated by stages
of a real drive cycle with the prefix settings of movement and operation. In the cycle modification
the following approaches are taken account: minimal rotation frequency in stable movement; the
transmission efficiency is variable with the speed, the weight, and the gear ratio; a new rotation
frequency for gear shifting; a motor braking stage and; a group of new equations for the fuel
consumption. New mathematical models were obtained for the fuel consumption indicators of the
heavy duty trucks with manual transmission. Furthermore, the indicator Automobile Work
Effectiveness Coefficient is presented. It describes the energy efficiency in the acceleration stage
involving the fuel energy during the impulsion of payload until it reaches a certain speed.
Key words:
drive cycle, fuel consumption, mathematical models, vehicle evaluation.
