The article presents a technical diagnostics of a car as a complex of goals and tasks connected with trouble-shooting of mechanisms and systems in order to eliminate them. We have considered the stages of computer diagnostics of different automobile systems such as diagnosing the engine, the brake system, steering and suspension. We have analyzed their components, the ways of troubleshooting and elimination recommendations. The article presents the main troubles transferred from the electronic control unit. The article also presents the stages of diagnosing the engine including external examination, listening to abnormal noises, checking the operating fluids and the engine management system, diagnosing the basic engine systems and checking the cylinders being filled. The article contains the list of main troubles and their reasons. One can also see diagnosing the brake system, its defects and remedies. The article presents diagnostics and repair of the suspender and graphics describing the check of the dismantled shock strut at the stand and tests of the shock strut without being dismantled. We have analyzed computer diagnostics and the problems it solves

The issue of the article is the procedure of diagnostics of the mobile agricultural techniques based on the implementation of the automatic control electronic systems. In particular, a ternary circuit is being created for the analysis of diagnostic protocols, which allows facilitating the specifying of the protocols, including compiling of documents describing the basic parameters, the structure and the constants of diagnostic protocols

The article analyzes the results of the evaluation of the filter element of the filter of thin clearing of fuel on the basis of the change in pressure in the common rail fuel supply system depending on mileage

The article presents the way to identify the mobile agricultural equipment technical status control perio-dicity based on the comparison of its defect-free per-formance given probability with its calculated value in order to decrease significantly the efforts to estimate control periodicity and increase the results authenticity at the expense of mobile agricultural equipment prob-able characteristics calculation

In recent years, in many countries around the world, much attention is paid to the issues of ensuring of rational use of energy resources, due to a number of objective factors, chief among which are: the lack of own energy resources to meet domestic energy needs; the sharp increase in the cost of production and the production of energy resources; further growth in energy needs; the presence of large potential opportunities to reduce unproductive losses of fuel and energy. In the world, the challenge now is to ensure a gradual but steady transfer of the economy on energy saving way of development. To achieve the goal of reducing energy costs we might use two ways: firstly, the widespread introduction of energy saving technologies, and secondly, the reduction of material production, improving its quality and service. In agriculture, the improvement of the technological process can be carried out using new tillage methods, improving the organization of production and tools. Further development of mechanization in agriculture will contribute to further growth of electrification in the agricultural sector, which will significantly reduce the use of the most expensive and limited energy resources. The article offers a technique of the estimation of the efficiency of consumption of energy in agricultural production. In order to compare the efficiency of machines in the cultivation and harvesting of potatoes, there was conducted an energy assessment of the operations of modern technology. As variables, there were investigated different operation modes of the machine: working speed and working width, depth of stroke of the working bodies. In the process of evaluating energy operations, modern technology to prepare the soil for planting potatoes was determined humidity, mechanical composition and soil type. As a main factor in the analysis of technological methods, we have taken the overall specific energy consumption and specific energy consumption for the digging below tuber formation. Analysis of theoretical researches of agricultural machinery has led to the conclusion that the energy cost of implementing the technological process in the machines of different designs varies

This article discusses the results of the studies made by the faculty and the staff of Ryazan State Agrotechnological University named after P.A. Kostychev confirmed with RF patents

At the present time there is a problem in storage of agriculture machine-tractor park, because when operating of agricultural machinery parts thereof are covered by contamination. The most heavily becomes dirty machinery working in the toughest conditions. Pollution promotes decrease the operational reliability, accelerating of corrosion and aging, reduce the quality of maintenance service and performance technique. One of the number of important factors when setting technique for storage is the clearing of by of various types pollution, because the during storage of cleaned surfaces, components and parts are subjected still greater destruction and corrosion. Removal of various kinds of pollution is an important technological process which has a significant impact on the preservation of appliances, performance of work, the quality of the repair and maintenance of cars, culture, production and human health. The article contains a classification of contamination depending on the difficulty of their removal and density, basic information on techniques and devices for purification of units and parts of agricultural machines, as well as on substances used for this. We have reviewed bombardment of surfaces with contaminated carbon dioxide ice particles that leads to its full destruction. We have improved technology and created a universal device and the experimental plant for cleaning parts and assemblies prior to storage, which are not only inferior, but also in the majority superior to technical and economic performance of existing analogues

The carried out analysis studies the influence of various factors on the preservation of agricultural products and shows that it is largely determined by design features of machinery and technological methods of use. The efficiency of agricultural and mobile trailer machines has been forming by service and storage. Low quality of work associated with the storage of agricultural machines is conditioned by the fact that the lack of financial capacity of rural producers on acquisitions of modern equipment and materials for carrying out the preparation of for long storage, and also the construction of modern agricultural machinery storage sites. If a car can be fully or partially protected from the solar radiation, rain and snow, simply by removing it in the room, under a canopy or covered with a protective cover, by the formation of condensation on the surface of the machine units and parts these ways to protect do not work. Enhancing of preservation of agricultural machinery is possible when protecting the vehicles from atmospheric precipitation in the form of snow and rain, influence of solar radiation, and also due to the change heat exchange processes of the machine with the environment that prevents the formation of moisture condensate on its surface, ie. we have to create conditions when cooling rate at which the surface of the machine would be equal to or less the rate of cooling air. This is possible through the use of a special design, which would prevent the intense heat radiation of the machine into the environment, ie, would reflect heat rays using its surface and return them to its surface and thus fulfill the role of the heat shield
