Experimental investigation of combustion, emissions and thermal balance of secondary butyl alcohol-gasoline blends in a spark ignition engine

The article deals with the possibility of the implementation of artificial intelligence, which will improve the efficiency of national economy, including the energy industry. The paper presents the principles of using neural networks and elements of artificial intelligence in the processes of production, transmission and consumption of electricity. It has been revealed that the use of artificial intelligence in the electric power industry will make it possible to minimize disruptions in power supply.

Implementation of artificial intelligence in the electric power industry

Biofuel, a cost-effective, safe, and environmentally benign fuel produced from renewable sources, has been accepted as a sustainable replacement and a panacea for the damaging effects of the exploration for and consumption of fossil-based fuels. The current work examines the classification, generation, and utilization of biofuels, particularly in internal combustion engine (ICE) applications. Biofuels are classified according to their physical state, technology maturity, the generation of feedstock, and the generation of products. The methods of production and the advantages of the application of biogas, bioalcohol, and hydrogen in spark ignition engines, as well as biodiesel, Fischer–Tropsch fuel, and dimethyl ether in compression ignition engines, in terms of engine performance and emission are highlighted. The generation of biofuels from waste helps in waste minimization, proper waste disposal, and sanitation. The utilization of biofuels in ICEs improves engine performance and mitigates the emission of poisonous gases. There is a need for appropriate policy frameworks to promote commercial production and seamless deployment of these biofuels for transportation applications with a view to guaranteeing energy security.

An Overview of the Classification, Production and Utilization of Biofuels for Internal Combustion Engine Applications

The current state of the economy and society is influenced by the global integration processes taking place in Eurasia - the creation of the Eurasian Economic Union, which should unite the markets for resources, goods and capital of the member states of the Eurasian Economic Union. One of the aspects of this process is the creation of a unified electricity market, which ensures free flow of electrical energy, free pricing and competition in the power industry. The purpose of this study is to study the degree of readiness of national energy systems for integration and to identify problems that impede the formation of the Common Electricity Market of the Eurasian Economic Union. The methods used were statistical analysis tools, a graphical method, comparisons and descriptions. The study was carried out on the basis of the use of information provided in the open access of the Eurasian Economic Union, national statistical services and energy companies. The authors have identified the main goals and objectives, as well as the requirements and expected results of the creation of the Common Electricity Market. As a result of the analysis of national power systems, a number of problems were identified that impede their convergence, including inconsistencies in the scale of production, various pricing mechanisms and electricity price regulation, differences in the energy balance of the Eurasian Economic Union member states, different levels of electricity prices, and a particular opinion Of the Republic of Belarus to the concept of market formation and the lack of unified borders of Armenia with other participating countries Union. The findings of the study indicate that by the stated date, namely July 1, 2019, the Common Electricity Market will most likely not be created for the reasons stated. To solve the identified problems, the authors propose several tools, one of the most important among them is the mechanism of regulatory and legal regulation of electricity markets at the national and supranational levels. Also, according to the authors, in the integration processes in the framework of the Eurasian Economic Union should consider the world experience of such political and economic associations.

Evaluation of diesel engine performance with high blended diesel-biodiesel fuel from waste cooking oil

Objectives: In this study, evaluation of the potential of energy recovery in spark ignition engine using RON 95 gasoline fuels. Methods: The engine has been operated at a single engine speeds of 3500 RPM with 50% of Wide Throttle Open (WTO). The potential of energy recovery was measured by means of engine effective power, Water Heat Losses (WHL) and Exhaust Heat Losses (EHL). Findings: Comparative analysis of the experimental results showed an improvement of 1.16%, 2.12% and 3.08% in EHL at 75°C, 50°C and 25°C, respectively, by taking 120°C as the reference temperature of EHL. The results of the contour plot showed that a trade-off between the WHL and EHL. Conclusion: Higher proportions of energy losses can be utilised by considering both WHL and EHL.
