Malfunctions of the elements of the fuel injection system lead to a deterioration in the performance of diesel engines. The largest proportion of faults that occur during the operation of battery injection systems are electro-hydraulic injectors. For the timely detection of malfunctions, the injectors are diagnosed. The most accurate determination of the technical condition of the injectors can be made using specialized diagnostic stands with their removal from the engine. As a rule, the diagnosis is a conclusion about the general technical condition of the injector. To ensure high quality and reduce the complexity of repairs, it is necessary to use new methods and tools that allow for in-depth diagnostics of injectors with the identification of specific defects. The purpose of the presented work is to identify possible differences in the change in the set of diagnostic parameters when changing individual structural parameters in order to be able to determine specific defects in injectors during their diagnosis.Materials and methods. The hydrodynamic processes occurring in the electro-hydraulic injector during its operation were described by a system of differential equations of the first order. Numerical experiments were carried out to study the influence of changes in structural parameters on diagnostic parameters. The calculations using the software environment for mathematical calculations Mathcad were carried out. The calculations at different combinations of pressures in the fuel accumulator and the duration of the control pulse corresponding to certain engine operating modes were carried out.Results.

The technological process of restoring a part should provide more than 80% of the resource and no more than 50% of the cost of a new part.

The problem of accelerating and cheapening the construction of roads without reducing their quality can be solved by creating a complex of continuous units. Units, following each other, carry out the whole complex of works aimed at roads construction. One of the elements of the continuous unit that forms the ditch is a straight-flow rotary ripper. It was found that in order to excavate the soil near the axis of rotation of the rotor of a straight-flow rotary ripper, a small rotor with a higher angular velocity should be installed, coaxially with a large rotor. The use of straight-flow rotary rippers for soil development is constrained by insufficient theoretical substantiation of their parameters. Before analysing the interaction of the elements of the working bodies of the straight-flow rotary ripper with the soil, it is necessary to clarify the structural layout of the small rotor.The method of research. The small rotor should contain two knives connected at the periphery by a disc to give rigidity to the knives; the cross-section of the knives is triangular with a sharpening angle of 20 °, for maximum transformation of the angle of sharpening, the knives must have a saber-shaped shape; two teeth located on the disk to loosen the soil and shift it towards the knives; a shaft tip of the small rotor, the diameter of which must exceed the width of the knife at the point of its connection with the shaft tip; a spiral knife at the end of the shaft tip to loosen the soil and shift it towards the knives. By constructing projections on the transverse-vertical plane of the blade of the knife, the tooth and the disc of the small rotor, when there is a different angle of deviation of the blade in the cutting plane, it is possible to identify the basic geometric parameters of the elements of the small rotor of the straight-flow rotary ripper.

This article presents the results of a study of the wear out effect the carbide tip for the cutting element of a milling machine on the resulting cutting strength when milling asphalt concrete. The relevance of the work is due to insufficient information about the wear out effect on the strength of cutting resistance, and, consequently, it is not possible to predict changes in loads on the working body of milling machines during its operation with worn cutting elements.Materials and methods. The experimental studies to determine the cutting resistance force that occurs during the milling of asphalt concrete with a maximum mineral aggregate size of 16 mm. used for the top layer of the coating and for roads with normal traffic conditions (A16vn), depending on the thickness of the chip being cut and the degree (percentage) of wear of the cutting element were carried out. To conduct the study, a pendulum stand, which is most suitable for studying the interaction of a single cutting element of a road milling cutter with asphalt concrete, was used.Results. As a result of experimental studies, it was possible to obtain the data allowing a reasonable approach to the choice of the interval of replacement of cutting elements during the operation of milling equipment, which, in future, will lead to an increase in the productivity of equipment and its service life.

Reducing the operating costs of motor fuel for cars is possible through the use of cheaper and at the same time less environmentally harmful alternative energy sources. The main problem with the use of these energy sources, especially for 1 category cars, is the underdeveloped infrastructure of the network of filling stations for alternative fuels. The main alternative type of motor fuel in the Russian Federation is natural gas. The use of compressed natural gas as a vehicle fuel on 1 category cars significantly increases zero mileage due to the remoteness of filling stations, which reduces the efficiency of using natural gas.

The article formulates the problems statement about equilibrium states in the model of a generalized transport system of the city, consisting of a street and road network, centers of mass gravity, places of residence of people, vehicles, as well as road users themselves, including passengers. The solution of these problems makes it possible to identify the equilibrium distributions of the system elements over various subsets of states (a subset of the elements of the road network; a subset of the center of mass gravity; a subset of trips of a certain type, etc.), depending on the type of vehicle, individual preferences, knowledge about the state of the transport system and other factors.At the same time, the transport system is considered as an object of research within the framework of the theory of macrosystems. A set of problems statements on the search for equilibrium states of the transport system for various modelling objects has been compiled for various structural levels (scales) of the objects under consideration.Materials and methods. In this paper, the theory of transport macrosystems is applied, which follows from a wellknown scientific discipline - the theory of macrosystems. Among its tasks there are statements about the distribution of elements over subsets of states and problems about the equilibrium of the system as a whole. In macroscopic systems, by definition, the stochastic behavior of a large number of elements transforms the deterministic behavior of the system as a whole. A macro system is thus a dynamic converter of the chaotic behavior of elements into a certain set of behavior parameters (phase variables) forming a space of small dimension. Therefore, within the framework of the theory of macrosystems, the basic concepts of entropy maximization at equilibrium states of the system are used. In this case, the distribution function of macrostates is selected depending on the method of filling some states with elements from the corresponding subsets; the necessary values of a priori probabilities and proofs of parametric properties of models of macrosystems with various statistics (Fermi-, Einstein- and Boltzmann-distributions). On the basis of the theory of macrosystems, for example, problems are solved to find equilibrium in such systems as: 1) megapolis with its functional and spatial structures (probabilistic states of hierarchical systems), 2) transport networks of cities formed by the movement of vehicles and residents of the city between different areas (distribution of trips along routes in the network); 3) logistics systems in the interregional exchange of products (problems of economic equilibrium in the exchange of resources).Results.
