Plis","doi":"10.15587/2706-5448.2020.215007","DOIUrl":"https://doi.org/10.15587/2706-5448.2020.215007","url":null,"abstract":"The object of research is an electronic microprocessor control system for gas internal combustion engines with spark ignition for operation on liquefied petroleum gas. The system consists of two main subsystems, the accumulative power supply common rail LPG injection subsystem and the contactless electronic ignition subsystem with a movable voltage distributor. In addition, the control system also includes a subsystem for controlling the filling of the cylinders with the charge of the working mixture, consisting of a throttle valve and an idle speed regulator with a conical damper. The control system, depending on the software version, is capable of providing group or sequential injection of liquefied petroleum gas into the inlet pipe of each cylinder in the area close to the inlet valve. Such a control system can be used when converting (re-equipping) both new diesel engines into spark-ignition gas engines, and those that are in operation. The feasibility of such a conversion is to reduce operating costs with powerful vehicles for diesel fuel, by replacing it with cheaper and environmentally friendly liquefied petroleum gas. \u0000 \u0000To test the efficiency of the control system, a D-240-LPG-«B» model gas engine was developed and manufactured to operate on liquefied petroleum gas. The gas engine was converted on the basis of the D-240 transport diesel engine (atmospheric, four-stroke, liquid-cooled, 4-cylinder engine with a piston diameter of 110 mm and a stroke of 125 mm). Reducing the compression ratio of the diesel engine was achieved by modifying a semi-closed diesel combustion chamber of the TsNIDI type into an open combustion chamber in the form of an axisymmetric «truncated cone». For efficient control of three subsystems of the D-240-LPG-«B» model gas engine, an electronic microprocessor control unit of the Avenir Gaz 37 «B» model was developed and manufactured. The tests carried out on the D-240-LPG-«B» gas engine with the Avenir Gaz 37 «B» control unit showed the efficiency of using the electronic microprocessor control system.","PeriodicalId":218996,"journal":{"name":"TransportRN: Transportation & Energy (Topic)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121879814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kovalchuk","doi":"10.15587/2706-5448.2020.207910","DOIUrl":"https://doi.org/10.15587/2706-5448.2020.207910","url":null,"abstract":"The object of research is the finance of the railway industry in terms of energy conservation. Since the role of railway transport in social production is unquestionably significant, because until a certain product is delivered to the consumer, it is not completely manufactured, so to speak, and can’t be used by the consumer. An important role in the work of railway transport is played by its finances, without which the work of enterprises is impossible, especially in conditions of using energy-saving technologies.<br><br>It is shown that the financial management of the transport industry in the context of energy conservation at the present stage of development of the railway industry and the country’s economy is one of the main areas of management activity. Financial management of transport enterprises is the process of coordinating all the determining components of the financial system to achieve the stable operation of transport enterprises and, no less important, its development. The content of such concepts as «financial management» and «finance of the railway industry enterprise» has been clarified based on a synthesis of various modern scientific approaches to the study of these categories and the identification of the main features for adaptation to energy saving conditions. So, let’s consider the finances of the railway transport company as the monetary system of the specified economic entity, that is, the totality of payments, receipts, distribution and use of funds in the process of its production and economic activity. Effective financial management of a railway company is an opportunity for organizational, financial and economic sustainability of a railway company in the context of energy conservation. At the same time, losses from compliance with the above conditions are minimized, thereby maximizing the economic added value of the enterprise during its operation and development. Consequently, the financial management of the transport industry company works by saving energy resources; it should use a management model that provides solutions to the interrelated tasks that arise with this method of managing.","PeriodicalId":218996,"journal":{"name":"TransportRN: Transportation & Energy (Topic)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125264424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Renewable biofuels are the best substitute to tackle the power crisis due to scarcity of fossil fuels. As the search for alternatives to fossil fuel intensifies in this age of modernization and industrialization, fueled by increasing energy costs, water hyacinth holds a sturdy promise in the 21st century biofuel industry. The LODHA Pond, city Banswara and PICHOLA Lake Udaipur are the major wetland in the Rajasthan state in INDIA, with the potential for production of large quantities of biomass of aquatic floating species, especially water hyacinth (Eicchornia crassipes and E. azurea), during the aquatic phase of the flood-pulse characteristic for this ecosystem. The biofuel from the non aquatic plant like water hyacinth will be used for the different uses and this will not produce and adverse effect to the any ecosystem of natural resources. The extraction of biofuel from water hyacinth is a very economical process because of the lesser cost of raw material &amp; its easy availability. Ethanol is produced from water hyacinth, an aquatic weed plant, comprising of good quantity of cellulose, hemi cellulose, lignin which increases the extraction rate of biofuel from it. Even after extraction of biofuels from water hyacinth, wastes are also utilized for the production of paper making in paper industries. This emerging biofuels based economy in the Rajasthan state in INDIA can be a good example of to human adaption to climate changes by managing carbon export of natural wetlands.","PeriodicalId":218996,"journal":{"name":"TransportRN: Transportation & Energy (Topic)","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116146023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, Azerbaijan is the only country in the region exporting gas to the international markets (Turkey, Russia, Georgia). For this reason, it is seen as “the provider and participant” of Southern Gas Corridor by EU. In this direction, Azerbaijan aims to be the country of an important and strategic natural gas exporter. From Shahdeniz field to the end European user, it targets to take part in the every ring of the value chain. These assumptions bring Azerbaijan to the position of a remarkable natural gas supplier for the export of large amount of gas to the European markets through Nabucco West. The implementation of the project with financial and technical capabilities of Azerbaijan and Turkey has made it a project to be realized between Turkey-Azerbaijan. TANAP means Turkey and Azerbaijan will emerge together in the European market for energy transportation. Along with Baku-Tbilisi-Ceyhan and Baku-Tbilisi-Erzurum, TANAP has reinforced Turkey’s position as a necessary energy corridor in delivering the energy resources of the Caspian Sea to the Western markets. In this paper, expected strategic and economic outcomes of TANAP are analyzed.","PeriodicalId":218996,"journal":{"name":"TransportRN: Transportation & Energy (Topic)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115215117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These technologies are hydraulic fracturing, directional drilling, and the worldwide build-out of liquefied natural gas (LNG) import and export facilities. Hydraulic fracturing and directional drilling are mainly responsible for the improvement in supply, while the richer LNG infrastructure is facilitating the worldwide transportation of gas and starting to knit the once fractured gas market into a truly world market. The consequences of these processes has dramatically different effects around the world, creating true winners and losers. This article assesses the impact of these natural gas developments on the world’s ten largest economies. It concludes that the United States is the largest beneficiary of these developments, followed by China, with Russia being the largest loser in the new world of natural gas.","PeriodicalId":218996,"journal":{"name":"TransportRN: Transportation & Energy (Topic)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121946172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
