The electromagnetic fuel injectors automotive are the gasoline injection systems main elements. The injectors perform the gasoline injection and its time of open condition, i.e injection duration determines the fuel quantity per working cycle [1]. The injectors are activated by solenoid and inject the gasoline in the engine manifold at the system pressure [2]. The gasoline injectors ensure precise fuel metering according to engine work state. The injectors are controlled by control signals, whose parameters are defined by the engine management system. The control devices are power transistors (drivers) in the electronic control unit (ECU). The injectors synchronizing and speed activating has a special significance and influence upon the increasing of the power and efficiency and the decreasing of the harmful emissions of the automotive engines. The synchronization of the electromagnetic gasoline injectors is connected by one hand of the injection according engine work order and by the other – with equal fuel injection duration and injection quantity. Meanwhile the injectors work at such conditions, which imposed constant compensation and adaptation activities by the ECU. This circumstance is connected with requirements of speed activating, which is measured by indicators, such as minimal electromagnetic activating force and minimal opening and closing time. This paper is considered the method of calculating the electromagnetic parameters of the automotive electromagnetic gasoline injectors for manifold gasoline injection.

Reveals the scientific and methodological principles of definition agro-technical period for harvesting of walnuts depending on intensity fall fruit and the quality nut kernel.

The identification of the heat exchange intensity at the work surface of the mold is defined by the base information of the type and movement of the solidification front. Parameters and their influence are shown on the type and movement of the solidification front: initial melt temperature; initial temperature of the mold; the ceramic coating on the work surface of the mold; distribution of the mass of the mold. The methodological link of these parameters is shown in the creation of each casting technology.

It is important to load and fix goods in railway wagons in well done way to reduce the number of accidents on the railway.
The bad way of loading and fixing of the goods in the railway wagons can bring a very dangerous results as a damage of the transported goods or accident of the train. This paper deals with the analysis of the railway infrastructure parameters which affect the well done way of loading and fixing of goods in railway wagons.

Studied the conditions and opportunities for impact of these indicators on the economic result of many downstream enterprises. An attempt was made to determine the degree of innovation impact, which serves as a basis for assessing the design decisions. The following are findings with recommendations for the use of this method of evaluation.

Developed method rationale parameters equipping items postharvest processing of grain under the coordination of programs with the characteristics of industrial harvesting of early grain crops and grain systems parameters given the variability of agrometeorological conditions of the region.

The development of effective medication-free treatment and means of animal injuries treatment is urgent task. The optimal parameters of electromagnetic field of ultra-high frequency range interacting with the bone tissues of animals have been determined. The aim of the work is to identify the high-frequency range of the electromagnetic field parameters in interaction with animal tissues using the developed mathematical model. The dependence of electric component amplitude of magnetic frequency field was investigated. It has been proved that the dimensions of the limbs and internal tissues significantly affect the internal distribution of the electromagnetic fields. The results of experimental studies have made it possible to determine the optimal frequency, power and radiation source arrangement for the injury treatment of different animal species. The application of electromagnetic radiation with optimal parameters intensifies metabolism on the diseased cells membrane level and assists more rapid recovery of the injured bone tissue.
