Bakaeva N.P., Saltykova O.L.
Abstract
The purpose of research is improvement of biochemical parameters of spring wheat grain quality. The studies were conducted in 2007-2010 in the conditions of forest-steppe of the Middle Volga Region. The object of the study was the released varieties of Kinelskaya 59 spring soft wheat grain. The soil of experimental plot is typical chernozem medium loamy, medium. Spring wheat was placed in crop rotation and green manure with clean steam. In crop rotations the following fertilizer were used: no fertilizer application (control) and application N22P22K22 before sowing (azofoska of 1.4 t/ha). Spring wheat crops in 2007 were treated in tillering stage with herbicide Difezan (0.2 l/ha); in 2008 – in the phase of tillering herbicide Logran (10 g/ha). In crop rotations in three different systems of primary tillage were studied. Found that in crop rotation with bare fallow total protein content was little more than link with green manure and steam amounted to an average of 12.7 percent. This was contributed to the increase in the protein fractions of wheat globulins by more than 5% of glutelins more than 9 percent. Thus, when plowing by 20-22 cm increased the accumulation fraction of that prolamins, and fertilizing (N22P22K22) contributed more knock-tunately fractions albumins an average of more than 6% and globulins by 16%, which led to an increase in total protein more than 5% compared to zero tillage. Depending on the subtype of clogging of crops in crop rotation and green manure with clean steam fractional composition of grain increased in the variant without weeds. The fraction of albumin was higher on average by 13%, globulins 11%, glutelins 21%, and the fraction of Pro-laminam has changed slightly. Young and perennial subtypes clogging of the wheat crops reduced the protein content on average by 7-9% in comparison with the variant without weeds.

Trots N.M., Gorshkova O.V.
Abstract
The purpose of this study is to develop agrotechnological methods of establishing and controlling the content of heavy metals in plant products. For laboratory experiments we used the typical black soil. The results of lead and copper in soil and plants of spring wheat variety Kinelskaya 59, with different levels of pollution in the conditions of a pot experiment. It is established that with the increase of applied doses of salts of heavy metals increases their content in soil and spring wheat seedlings. The percentage of mobility in the soil of copper and lead in the soil increases with the pollution level 2.9 times and 9.2 times, respectively. With increasing doses of copper and lead increases the concentration of plant-available forms of nitrogen and phosphorus. For all variants of experience is typical acropetal distribution of heavy metals in plants – copper: the roots (46.59) > shoots (of 14.66); lead: the roots (47.0) > shoots (12.78). The value of Iа decreases with increasing dose of applied salt that is indicative of the culture of spring wheat variety Kinelskaya 59 barrier. High correlation observed between the content of copper in plant roots and gross values (r = 0.98) and mobile forms(r = 0.94) in the soil. The value of copper in the shoots of plants are weaker related to the content of the element in the soil (r = 0.66). Between the content of gross and mobile forms of lead in soil revealed a high correlation (r = 1.00), the same value when item is marked with the plant roots and shoots.

Inshakov A.P., Kurbakov I.I., Kurbakova M.S.
Abstract
The purpose of the research is to identify the peculiarities of interconnection of dynamic characteristics of the turbocharger TKR 6.1 and the engine D-245-35 in the presence of a fault in the pressurization system. In the practice of fault finding in the system of supercharging of automotive engine widely used method of diagnosis, OS-nated steak subs on the measurement of the boost pressure in the nominal modes. In terms of the service companies due to the lack of brake stands to estimate the load mode is often not possible. For acceleration of the turbocharger and engine at the department of mobile power tools, national research of Mordovsky State University named after N. P. Ogarev created diagnostic complex consisting of forming unit of the source signals, the optical sensor shaft speed of the turbocharger, sensor of frequency of rotation of the motor shaft, the linear displacement transducer arm balancing machines, analog-to-digital Converter, software and a personal computer. The tests were carried out on the engine MMZ D-245-35, with an installed turbocharger TKR-6.1, simulation of the working regimes was carried out on the roller-brake stand. The test results obtained a series of characteristics of the acceleration of the turbocharger engine D-245-35 and TKR-6.1 with a step input exposure. Analysis of the data showed that the presence of a malfunction of the boost «leak turbine inlet», «air filter clogged» leads to an increase in the transient time and reducing the frequency of rotation of the rotor TKR in all modes. Spaced- out characteristic obtained in idling mode in the fault conditions «loss of gases after the compressor» is accompanied by the growth of the amplitude value of the shaft speed TCR and the reduction of time of transition. This feature of the waveform of the acceleration allows us to identify faults of this kind in the diagnosis of the supercharging system.

Bychenin A.P., Chernikov O.N., Prikazchikov M.S.
Abstract
The purpose of research is to estimate influence of vegetable oils (10%) by its use for quality of tribology properties of diesel fuel. The technique and results of basic researches of antiwear properties of mixed fuel with additive of vegetable oils (mustard, linseed and rape) are given. Researches were conducted by means of universal tribometer of the TU type with four-ball frictional unit. Concentration of vegetable oils in fuel are changed from 0 to 10% on volume with 2% step. Loading, frequency of spindle rotation and material of frictional unit details didn't change. For example researches showed that by of mustard oil of 2% concentration on volume the average diameter of a spot of wear decreased by 29% (with 0.258 when using diesel fuel without additives to 0.183 mm at addition of 2% of mustard oil). At concentration of mustard oil of 4% the average diameter of a spot of wear decreased by 35.4% of the initial. At further increase in concentration of mustard oil (6, 8 and 10% on volume) decrease in diameter of a spot of wear made respectively 37.3%, 40% and 43%. In case of use of linseed and rape oil similar regularities are observed. It is established that for substantial increase the tribology properties of diesel fuel is enough to enter into its structure 2-4% of vegetable oils on volume. The further increase in concentration of antiwear additive of considerable effect doesn't give, but use the mixed fuels with the content of vegetable oils to 30% on volume is rational from the point of view of economy of fuels of an oil origin.

Ukhanov A.P., Ukhanov D.A., Sidorov E.A., Yakunin A.I.
Abstract
The mode of independent idling, characterized by an impaired process flow, unproductive fuel consumption and increased emissions of harmful substances into the atmosphere, is the most unfavorable mode of the diesel engine operation. Therefore, the aim of the research is to reveal the peculiarities of the tractor diesel engine operation by the camelina-mineral fuel in the mode of independent idling. Camelina-mineral fuel is a mixture of camelina oil and mineral diesel fuel in certain ratio of these components. To assess the possibility of using the camelina oil as biological component of diesel mixed fuel, an experimental study of the D-243 diesel engine in idling mode was carried out, and the degree of influence of the different ratio of the components of the mixed fuel on its parameters was determined. The researches were carried out with the diesel fuel on the L-0.2-62 mineral fuel and the camelina-mineral fuel with a ratio of the biological and mineral components: 25% RyzhM + 75% DT; 50% RyzhM + 50% DT; 75% RyzhM + 25% DT; 90% RyzhM + 10% DT and 90% RyzhM + 10% DT (US). For the parameters of the diesel, the excess air factor, the filling ratio of the diesel cylinder with fresh charge, the maximum cycle pressure, the hourly fuel consumption, smoke and carbon monoxide content in the exhaust gases are taken. It is established that when the diesel engine works on camelina-mineral fuel mode the minimum sustainable speed of the crankshaft idle speed 800 min-1 the values of maximum cycle pressure (6.3 MPa) and the filling ratio of the cylinders of a diesel engine the fresh charge (0,87) remain unchanged. The coefficient of excess air, increasing in mixed fuel shares of camelina oil to 90%, reduced from 7.187 to 4.619, while fuel consumption increases of 1.1 kg/h 2 kg/h. The best environmental indicators are observed when working on red-and-mineral fuel 50% RyzhM + 50% DT. Handling mixed fuel with ultrasound reduces fuel consumption, smoke and content of carbon oxide in the exhaust gas relative to the mixed fuel not treated with ultrasound.

Kanaev M.A., Karpov O.V., Vasilev S.A., Fathutdinov M.R.
Abstract
The purpose of research is to improve the dosing of mineral fertilizers sowing unit, depending on the physico-mechanical properties of the soil. In modern technologies of precision farming with differentiated application of mineral fertilizers, data from various sensors, results of analyzes of soil samples and aerial photography are mainly used, without taking into account factor such as the depth of the humus horizon, which largely determines the soil fertility. On the basis of the Samara State Agricultural Academy, studies are underway on the effect of the depth of the humus horizon on the fertility of the soil. Several machines have been developed for differentiating mineral fertilizers with spreader and cultivator. Currently, a system of differentiated application of mineral fertilizers is being developed for sowing agricultural crops and it is planned to produce a set of equipment for a standard seeder UCS-8 Vesta. A constructive scheme of the device for determining the traction resistance is presented, which is closely related to the depth of occurrence of the humus layer. The main working element of this device is a deformer in the form of a knife, with a dihedral grinding. The article presents theoretical studies of the effect of forces acting on a deformer. Based on the results of the theoretical justification of the technological process of the proposed scheme for determining the traction resistance, the load dependencies on the strain gauge link were derived depending on the drag resistance of the deformer, which is determined by its basic design and technological parameters and the physical and mechanical properties of the soil. The obtained dependences of the traction resistance of the working organs of the tillage implement will theoretically determine the additional energy costs from the introduction of the deformer in the design stage at the design stage of the machine and outline the directions for their optimization.
