ABSTRACT: Over the past few years, changes have been observed in the behavior of typical performance curves, after higher technology has been incorporated into the agricultural tractor engines, either to satisfy the ceiling of the new pollutant gas emission limits or to achieve better efficiency. The aim of this study was to assess the typical performance behavior of an agricultural tractor engine, possessing electronic injection management, turbocharger, aftercooler and EGR (Exhaust Gas Recirculation) treatment system. An analysis was done of the information the manufacturers provided, in terms of nominal power, maximum power and maximum power with Booster, maximum torque and maximum torque with Booster. From the results, the percentage difference between the nominal power and maximum power were found to hover anywhere from 1.49 to 11.97%, for the same manufacturer, 0% in another manufacturer and 9% in a third manufacturer, for all the models. Similar results were noted for the data reported on the maximum torque and maximum torque with Booster, giving 0.62% as the minimum value, 7.44% as the average value and 12.65% as the maximum value for the entire series.

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.

Testing of 3 phase induction motors with a variety of wire diameters. First, find out the ideal wire size on an induction motor. Second, ratio of the power used on an induction motor with different winding wire sizes. Third, to find out the torque produced by an induction motor with different wire winding sizes. Then, The induction motor test was performed by taking the power data used on two motors with a diameter of 0.6 mm and 0.5 mm winding wire, RPM data and torque produced by an induction motor with a diameter of 0.6 mm and 0.5 mm. So, we can get the results the induction motor with a diameter of 0.6 mm wire uses as maximum power of 549.10 Watt or more than the induction motor with a diameter of a wire wound of 0.5 mm which only uses a maximum power of 345.95 Watt, the wire diameter induction motor winding 0.6 mm produces a maximum torque of 746.92 Nm or greater than an induction motor with a diameter of 0.5 mm winding wire which only produces a maximum torque of 383.97 Nm. So, It can be conclude that the more number of revolutions per minute (RPM), the torque produced will be smaller, then, the greater the torque produced, the more power is used.

The tire inflation pressure, among other factors, determines the efficiency in which a tractor can exert traction. It was studied the effect of using two tire inflation pressures, 110.4 kPa in the front and rear wheels, 124.2 kPa in the front wheel and 138 kPa in the rear wheels, the energetic efficiency of an agricultural tractor of 147 kW of engine power, in the displacement speed of 6.0 km.h-1, on track with firm surface, with the tractor engine speed of 2000 rpm. For each condition of the tire pressure, the tested tractor was subjected to constant forces in the drawbar of 45 kN and 50 kN, covering 30 meters. It was used a randomized complete block with a 2x2 factorial arrangement (tire pressure and drawbar power) with four replications, totaling 16 experimental units. Data were subjected to analysis of variance, using the Tukey test at 5% probability for comparison averages. The lowest hourly and specific fuel consumption, the lowest slippage of the wheelsets and the highest efficiency in the drawbar was obtained with the tire inflation pressure of 110.4 kPa in the front and rear tires of the tractor, highlighting that lower pressures improve energetic and operational performance of the tractor.

Abstract A novel realistic Work Criteria Function (WCF) approach has been used to analyze the ideal air-standard Diesel cycle. The WCF formulation gives rise to a new performance criterion which is termed as efficient power density (EPD). Thermodynamic analysis under maximum efficient power density (MEPD) conditions has been performed and compared with other available performance criteria using variable specific heats of the working fluid. The results obtained from this analysis prove that the engine designed under MEPD conditions is very efficient and the size of the engine is reduced significantly compared to those designed under maximum efficient power (MEP), maximum power density (MPD), and maximum power (MP) criteria. Harmful emissions like {\mathrm{NO}_{\mathrm{x}}} may decrease considerably at higher values of the maximum cycle temperature ratio (ξ). The effect of variable specific heats of operational fluid on the actual cycle’s performance has a significant impact on engine performance and should be incorporated when evaluating practical cycle engines. The results obtained in the current study have scientific importance and could be an essential guide for the design of real Diesel engines by engine manufacturers.

During everyday operations with tractors, drivers are exposed to harmful effects of various factors. In addition to unfavourable temperature and humidity, dust and noise, one of the factors harmful to driver’s health is vibrations. They come from the tractor engine and from the roughness of the ground and are transferred to the cab and through the seat to the body of the driver. In case of high level magnitude vibrations and a long period of exposure to them, many health problems occur. The harmful effect of the vibrations is especially obvious in older models of tractors. High intensities of vibrations (above permitted limits) were found during the measurements of vibrations at the driver seat in such tractors. This study is an attempt to reduce the vibration levels using various vibration-absorbing components, such as cushions, at driver’s seat. The results of the measurements showed that the vibration levels were significantly lower in comparison to original seats.
