Determining the standard fuel consumption of road vehicles by using method of active type experiment.

Many specialists say that the factorial experiment if used properly may bring remarkable results in the practical experiments in the field of motor vehicles. In order to prove these claims, with this paper we will present some theoretical considerations regarding the mathematical model used, but also the practical research carried out to obtain some objective functions such as the average fuel consumption in l/100km. In the context of the research, we present some examples of calculation regarding the actual mathematical modelling as well as, the manner in which one can reach the real values of the objective functions. During the practical research, the influence of disturbing factors suchs as temperature, air presure and humidity, wind speed and vehicle speed, wich can substantially influence the fuel consumption of road vehicle, was taken into account. In the end, some conclusions and directions regarding the research of the modelling are presented. [ABSTRACT FROM AUTHOR]
