Determination of operational fuel performance of dump trucks in the process of unloading the platform

Abstract

Fuel and economic performance is one of the most important operational indicators that determine the quality of modern motor vehicles and are included in the set of criteria for assessing the constructive improvement of vehicles. The rapid pace of development of the construction, agricultural and other industries ensures an increase in the percentage of use of modern specialized vehicles, which, in turn, ensures an increase in the use of fuel and energy resources, so it is of great practical importance for the efficient use of fuel to improve the fuel efficiency of vehicles during transportation. One of the most effective ways to reduce fuel consumption is to increase its fuel efficiency by optimizing the parameters of the engine's operating mode during transportation, taking into account the design parameters of the specialized vehicle and the transported cargo. Dump trucks are designed to transport various (mostly bulk) cargoes and belong to the group of special road transport vehicles that are in great demand in Ukraine. The factors that influence the demand for this special equipment for cargo transportation are as follows: versatility and functionality, as the dump truck is equipped with the function of automatic unloading of cargo. The body is unloaded by tipping it mechanically. This method allows you to unload bulk materials, and not only bulk materials, to a clearly defined place and minimize losses for additional operations. The scope of application of this type of transport is quite wide: in construction, in quarries during the development of mineral resources, in the agricultural sector and at manufacturing enterprises. Today, the demand for dump trucks is growing in Ukraine. According to 2016 statistics, sales of new dump trucks accounted for 46%. At the beginning of 2017, statistics showed a 36% increase in this special equipment compared to 2016, and in 2018, sales of dump trucks in Ukraine amounted to 21.9%.
