Abstract The authors got the expressions, which consider the inertness of the elements of the system of continuous control of the convergence of the controlled wheels of motor transport means in the process of motion, which use with tuning of system makes it possible to increase the accuracy of regulation.
Keywords motor transport means; the convergence of the controlled wheels; control system; accuracy; inertness.
Abstract The article is been reviewed the basic anti-slip means. The question of reducing the efficiency of anti-lock braking system in the process of equipping a winter spiked tires are been con-sidered. The statistics with respect to equipping light weight vehicles with spiked tires in the city on Moscow during winter are been shown. The given position brings about the necessity of testing procedures of the interrelation of winter spike tires and ABS.
Abstract The article contains the concept and principles of existing single-track brake systems of vehicles. Discusses their advantages and disadvantages. We propose a consistent brake actuator with one control. We propose a type of field testing single-track vehicles. The results of comparative analysis of different types for different types of brake single-track vehicle.

Abstract The new designs of the humidifiers offered in the scientific and technical literature and patent materials of industrially developed countries of the world different by improved characteristics are considered. For maintenance of necessary humidity of air in inhabited and industrial premises humidifiers are entered into central airs and air conditioners.
Keywords a humidifier, the conditioner, the air conditioning system, air, water, humidity, atmosphere, a premise.
Abstract In article the causes and types of losses of efficiency of the equipment are analysed. For an estimation of use of the equipment it is formulated the metrics named by a level of technological efficiency. Classification of condi-tions and an operating time of the equipment is examined. It is analysed reliability, as metric of an performance of the equipment.
Keywords road and construction machines, maintenance, reliability, effectiveness, available.
Abstract In the article reasons for spare parts demand are considered. Relevance of replenishment systems optimization is shown. The most important inventory management tasks are listed. Current calculating methods for spare parts requirement are described. Means of queuing theory implementation for solving the inventory management tasks are proposed.
Abstract In clause problems which have been solved during research of the air field tower equipped by an automatic regulator of coupling weight, measured parameters are described at carrying out of natural experiment and the equipment applied to it. The basic results of research are presented.
Keywords laboratory-field researches, automatic adjustment, the tractor-tower, coupling weight.
Abstract The study deals with a subject of snow removal and its utilization in Moscow. It also includes the government standards for winter road maintenance and the snow removal cost structure. Besides there is a standing time anal-ysis for the tracks, waiting in a queue for unloading on the snow-melting station “Shenogino”, and suggestion for improving the snow removal administration in the city.
Keywords snow removal, snow removal costs, standing time, imitation model.
Abstract The article describes the signal processing transducers (sensors) that display different indicators of the engine, its synchronization between itself and the application of mathematical modeling to test the reliability of the data collected in a universal software and hardware complex for in-depth diagnosis of the quality of the flow of the working process in automotive engines.
Keywords automotive diagnostics, diagnostic equipment, internal combustion engines, sensors, indicator diagram, the instantaneous angular velocity and moment of resistance forces.
Abstract In the article are considered possibility of use of the generalized indicator as measures of dynamic development with reference to transport system of region. The dynamics of change in the optimization criterion of economic development of the transport system on an example of the Tyumen region is defined.
Keywords transport system, regional economy, indicators of economic development.
Abstract In article are considered existing sources of investments for updating of vehicles in the organizations of passenger transport of the general using. The mechanism based on use of target financing with reservation of amortization charges is offered. The technique of an estimation and a choice of various sources of the investments necessary for updating of vehicles is developed.
Keywords sources of investments, updating of vehicles, target financing.
Abstract This paper considers the route discrete optimization on graphs. Here it is presented the evidence of branch-and-bound method inaccuracy for solving the traveling salesman problem. We propose an improved algorithm to obtain the exact decision along.
