for snow removal from roads used by different snow-clearing equipment. The efficiency of its use is determined by the road conditions. This is especially true for snow plows in settlements with elements of arrangement of road (curbs, sidewalks, road barriers, stopping points). In these circumstances widespread machine dumps. The ability to develop, manufacture and operation of dumps of snow plows on small and medium-sized enterprises defines their widespread use and a variety of designs. Promising to modernize the necessary conditions under heaps of snow removal from roads and sidewalks. The decision in this case take into account the comprehensive approach, comprising as an account of the influence of external factors - the operating conditions of the machine, and internal changes in the parameters of the machine. Analysis of the problem has allowed to hypothesize on the design of blade snow removal machines. In order to develop a scheme blade methodology for the study and design of experiments, the basic factors of influence on the resistance. The design blade for snowplows and virtual model to assess performance.

A significant number of units and special motor vehicles operated in a low freezing temperatures of the Far North and the Arctic. Preserving the art in these conditions depends primarily on the reliability of the internal combustion engine startup. For this purpose, a means of preparation of heat from external heat sources. In the context of the autonomous functioning of the machine it is necessary to use its internal sources. This can be accomplished using a heat recovery system of the internal combustion engine. To do this, include thermal batteries. In order to increase their efficiency (increasing the thermal capacity, reduce the size) Three constructions of the dual-chamber heat accumulator. To describe the heat transfer of the heat accumulator defines the conditions of uniqueness, according to which a simulation of thermal processes heat storage
