“…The research object is an MTU based on the Kirovets tractor with a 16F/8R speed gearbox with hydraulically controlled friction clutches. This transmission was described in [8,9]. The existing ACS used on various agricultural machines are divided into two classes: constant power systems that maintain a constant engine operation mode and power for a given position of the system adjuster, and constant speed systems that maintain the machine speed [10].…”

“…Controlling the skidding of the tractor's driving wheels is especially important in the maximum power mode. Skidding by more than 30 % should not be allowed since this can significantly aggravate the performance of the MTU and result in soil destruction [9]. Therefore, in case of increased skidding of the ACS, it is necessary to lower the transmission in the gearbox and reduce the speed mode of the engine, generating a signal that operation is impossible if maximum permissible skidding is reached for the given conditions of preserving soil fertility.…”

The paper considers a digital model of a wheeled agricultural tractor, as well as algorithms for automatic control of the engine and transmission. Simulation of the working conditions was performed in MATLAB and its applications, Simulink, Sim-scape. The tractor model is based on a systemic approach and includes such subsystems as the engine, transmission, undercarriage, hook load, and control actions from the operator, as well as functions of logic and optimisation for gear shifting. With the help of fundamental blocks of the Matlab package, models of tractor physical components are created. The fundamental blocks of the package serve to model the physical components of the tractor: engine, transmission control system, the transmission that includes friction clutches, gears, shafts ties with the necessary characteristics. Simulation of the working processes of a tractor unit is performed with optimisation of the laws of engine and transmission control according to the criterion of fuel efficiency and maximum power usage. The control system parameters were optimised in the transport mode, as well as in the maximum power mode in the traction range. As an illustration of the use of this analysis method, a solution to the problem of optimisation of an agricultural wheeled tractor operating modes is given. The results of this mathematical simulation are presented in this paper. Parameters of tractor operation control algorithm, which provide minimum fuel consumption in tractor operating cycles, are given. The research results showed the effectiveness of the proposed algorithms and the digital model. The presented digital model allows to debug the operating tractor control algorithms and offers an engineering practice for optimising automatic control of the agricultural tractor engine and transmission.

“…Cooling plays an important role in maintaining engine performance under severe mechanical and thermal conditions. Modern heavy-duty engines need more efficient cooling systems, which is achieved, along with other measures, through development of more optimized designs of cooling jackets, allowing increased flowrates in critical zones where higher temperatures may occur [1]. Another way to increase cooling rate is by utilizing the effect of subcooled nucleate boiling.…”

The ever increasing power rates of modern IC engines pose a great challenge for maintaining the optimal temperature conditions. The current trend in the thermal management of IC engines is to utilize the limited and controlled nucleate boiling to achieve higher heat transfer rates. The modern CFD instrumentation offers a wide range of methods for predicting nucleate and film boiling. Of the available models the mechanistic RPI wall boiling model is selected in present paper in the cojuntion with the Eulerian multiphase model available in ANSYS Fluent solver to simulate subcooled nucleate boiling in engine cooling jacket.Results obtained from the simulation of boiling flow in cooling passages is then compared with the experimental data from author’s previous work and show a decent agreement.
