Abstract: Mining and technical factors and increasing the depth of the quarry are some of the main reasons for the accumulation of exhaust gases of internal combustion engines and deterioration of the environmental situation in the quarry. This leads to stoppage of the production process and downtime of excavator-truck complexes, and as a result has a negative impact on the economy of the enterprise. When developing new dump trucks it is necessary to increase environmental friendliness and reduce fuel consumption at the same time. To date, the task of choosing the engine for autonomous dump trucks is relevant, and in the framework of ensuring import substitution is especially important analysis of domestic engines for the localization of production in Russia. In this article the engines for quarry dump trucks in the payload range of 218-255 tons are considered. Key indicators are defined, namely: fuel consumption, specific power per ton of transported cargo and specific power per total mass of the machine. Among dump trucks of 218-255 tons payload capacity there is on the average 8 kW/t power density per one ton of payload capacity. At full mass of dump trucks, the average value is 4,7 kW/t. The brief analysis of operating and perspective Russian engines for quarry dump trucks is resulted. The way of engine installation on the frame of the dump truck is considered. It is established that for the moment UDMZ engine is perspective for autonomous mine dump truck with 240 tons payload capacity.
