The existence of an effective financial and economic security system, which will provide the protection of the enterprise from the threats is one of the most important aspect of sustainable business growth providing and formation of positive results of its financial activities in modern conditions of the economic processes imbalance. The protection is conditioned by the ability of the enterprise authorities: to provide sustainable business growth of the enterprise, to neutralize the negative impact of the crisis economy, to form an adequate accounting system of financial flows, to strengthen operating effectiveness of the control system, to provide the protection of the trade secret information confidentiality on appropriate levels.Modern scientific researches indicate there is impossible to find exit from crisis, to stabilize the economic situation, to create an effective mechanism of doing business without unified system of business financial and economic security. The search of the main ways of business acceleration with minimal expenses for forming of effective system of enterprises functioning aimed at maximization of profits and harmonization of relations between business stakeholders is very relevance in the conditions of post-crisis reconstruction.It should be taken into account the fact that production and economic systems, regardless of the form of ownership, are characterized by the presence of constant risk and threats associated with the dynamics of the external and internal environment of their functioning. The financial and economic security of a business depends on the state of the country's monetary security. It should also be noted that at present the financial security of Ukraine is under threat, since all components of ensuring financial and economic security are in danger. The problems of their own economic security arise before each type of business, not only in times of crisis, but also when working in a stable economic environment, the set of targets to be solved in this case has a significant difference.The instability of the economic and political situation in the modern world creates great tensions and serious problems to ensure the financial security of enterprises, which is associated with solving economic and legal problems, as well as protecting economic interests and property rights of economic entities -physical and legal persons.The financial security of the enterprise, as the main economic entity of the modern economy, occupies an important place among the indicators of financial security at other levels, as the security of the enterprise is the basis of both economic security in general and financial security in particular.Financial security plays a significant role in the management of the enterprise, helps protect its financial and economic interests from negative internal and external threats, protects the financial interests of business owners, controls the financial resources of the company, able to withstand existing and emerging risks that cause financial damage change t...

The change in the viscosity of diesel fuel with dissolved hydrogen, the rate of dissolution of hydrogen in the diesel fuel, and the hydrogen diffusion coefficient in diesel fuel were experimentally determined. Dissolving hydrogen in liquid fuel changes its physical-chemical properties. It has been found that the viscosity and density of diesel fuel change little when it is saturated with hydrogen. The flashpoint in a closed crucible is reduced by 3–4 °C. The rate of dissolution of hydrogen in diesel fuel has been investigated. It has been found that the diffusion coefficient of hydrogen in diesel fuel depends significantly on the initial concentration of H2 in the fuel. The liquid fuel is advisable to supply with saturated hydrogen for the safety of the heat engine operation. The design of the hydrogen fuel saturation system with a special hydrogen sensor based on the MQ-8 sensor was proposed. The system of protection of the research stand from unauthorized emissions of hydrogen into the environment has been worked out. The protection ensures the shutdown of the stand equipment when the hydrogen concentration in the zone of its generation and supply to the fuel is at the level of 1%.
