Abstract

The subject matter of the article is the he process of preparation for starting and start-up of tank engines in different operating conditions. The goal of the study is the development and technical implementation of the algorithm of pre-start control and start-up of electric ignition system of internal combustion engines of armaments of millitary techniques units. systems. The tasks to be solved are: to analyze the tank electric start engines systemsl and start-up engine control, to determine the main elements failures of the electric tank engine start-up system, the causes of their occurrence, methods of elimination and to form the space of controlled start-up parameters, by functional-logical model of the tank start-up engine system diagnosis to determine the sequence of preparation operations for start-up and start-up of the engine, to draw up the minimized table of failures functions and on its basis to develop algorithm of pre-control engines of armored and military technics units. General scientific and special methods of scientific knowledge are used. The following results are obtained. On the basis of the systematic analysis, the efficiency of the use of circuit diagrams for troubleshooting the electrical start-up of tank engines was evaluated. Using the structural-functional method and formalization of the main faults and failures in the engine start-up system, a diagnostic model was created and sufficient depth of forecast was determined. Using mathematical apparatus of algebra of logic was drawing up of table of failures functions (TFF) with the subsequent transformation of it into the minimized table of failure functions (MTFF), on the basis of algorithm of engine start-up control of armored and military technics units. Conclusions. Electric start-up systems, which are part of the tank, directly affect the formation of combat properties of armored and military technic units. Their composition and structure begin with the tasks of providing and commissioning internal combustion engines (ICE), especially in low temperatures. Due to the rapid development of electrical systems, the issue of the organization and technology of repair of armored vehicles, especially in the field, has become much more complicated. Experience in the operation of armored and military technics shows that the durability and safety of engines and starter batteries largely depends on the quality of preparation for starting and starting engines in different conditions. There are numerous instances of engine start-up without sufficient coolant and engine oil, especially during emergency exits of the machine, as well as cases of premature discharge of the batteries due to inaccurate adherence to the engine start-up mode. The proposed algorithm can be used both by repair units and directly by tank crews to reduce the time to restore the performance of the tank starter system.
