Application prospects of elastic reactive linkage in tractor power train
Abstract
The paper analyzes prospects of application of elastic reactive linkage in tractor power train for the purpose of decreasing of its dynamic loading under transient modes (turning, acceleration, deceleration). The three-dimensional dynamic model of tractor power train with elastic clutch and without one is developed and investigated.

Modeling of reciprocating engine cycle in the process of exhaust gases recirculation
Abstract
Operating model of two-cylinder engine with closed crankcase ventilation system is presented. Differential equation system describing processes proceeding in cylinder, inlet and outlet lines is obtained. Program for calculation of processes of the engine with bypass of exhaust gases into inlet line is developed.

Theoretical basis for creation of irrigated packing of regular structure intended for air coolers in cabs of wheeled and tracked vehicles
Abstract
The paper discusses the process of heat transfer in the adiabatic lamellar packings for evaporative air coolers in cabs. Issue of heat transfer enhancement is also studied taking into account the specifics of the subject of application. Formulas for determination of parametric indices of the innovative packing are obtained.

Anticorrosion properties of antifreeze of internal combustion engine cooling system
Abstract
Anticorrosion properties of carboxylated antifreeze are investigated. It is found that long-time contact between coolant liquid and steel changes neither surface condition of specimens nor mass of them. It is demonstrated that steel surface under electrochemical corrosion conditions can in some cases take on the property of anticorrosion barrier.

Influence of tractor fleet on technical equipment indices and resource availability of mechanized agricultural production
Abstract
Results of mathematical treatment of statistic data on work of agricultural organizations in Russia are given. Linear relationship between number of statistic tractors and agricultural machines is shown. Equivalent ratio between tractor fleet reduction and reduction of arable land area and number of jobs is revealed.
