Energy Consumption Prediction and Control Algorithm for Hybrid Electric Vehicles Based on an Equivalent Minimum Fuel Consumption Model

The development of hybrid technology can effectively solve the problems of the high pollution and energy consumption levels of automobiles. Therefore, an energy consumption prediction and control algorithm for hybrid vehicles based on a minimum equivalent fuel consumption model is proposed. The model’s battery power consumption is equivalent to the fuel consumption, and the sum of the engine fuel consumption and the battery equivalent fuel consumption is established as the objective function. By utilizing these factors, an innovative minimum equivalent fuel consumption model was constructed that could be used to measure the energy efficiency of hybrid vehicles. The longitudinal force result of braking force distribution control was obtained, as well as the energy consumption prediction structure of a hybrid electric vehicle. The rolling resistance, air resistance, and climbing resistance of the hybrid electric vehicles were calculated, and the energy consumption control algorithm for hybrid electric vehicles was constructed according to the calculation results. The experimental results indicated that under this research algorithm, the driving energy consumption of hybrid electric vehicles was relatively low and the energy consumption and energy efficiency measurements effectively met the actual demand, and the energy consumption prediction and control results were good.

Experimental study on the load control strategy of ammonia-hydrogen dual-fuel internal combustion engine for hybrid power system

The development of hybrid technology and the use of zero-carbon fuels are effective means to improve energy efficiency and reduce carbon emissions. In this study, the Miller cycle spark ignition engine was used, and four load control strategies of throttle, ammonia-hydrogen ratio, air–fuel ratio, and variable valve timing were used to conduct experimental research on the ammonia-hydrogen engine. The experimental results show that the throttle strategy provides the widest output range, and the BMEP is raised from a minimum of 1 bar to 7.4 bar. The ammonia-hydrogen mixing ratio strategy is suitable for cold start conditions, fully utilizing the good combustion characteristics of hydrogen, and at the same time reducing the amount of hydrogen used in the heat engine process as much as possible. The air–fuel ratio strategy provides the highest thermal efficiency with a maximum BTE approaching 40%. It satisfies the energy-saving demand under the single-point working condition of the engine in the series mode. The variable valve timing strategy can realize switching between BMEP between 3.5 bar and 6.5 bar, and keep BTE above 33%. The valve timing strategy can not only provide a wider load adjustment range but also maintain high thermal efficiency. Finally, combining the effects of the four control strategies and the typical operating modes of the hybrid system, this study suggests that the throttle strategy is suitable for the feed mode, the VVT strategy is suitable for the parallel mode, the ammonia-hydrogen mixture ratio strategy is suitable for the cold start condition, and the air–fuel ratio control is suitable for the series mode.

Повышение энергетической эффективности локомотивов с накопителями энергии

Objective: The development of hybrid technologies is an aspect that carries serious changes for the railway industry, its design and technological base. These changes provide the scientific and technological breakthroughs to a much greater extent than the implementation of any new projects in traditional forms. Methods: Of great interest is the solution to the problem of hybrid locomotives and related power supply interaction. In addition, there are problems of quality and reliability of the rolling stock. The relationship between the three sets of technology, as well as the problem of support quality of the latter, becomes essential for the successful implementation of hybrid locomotives with a combined power plant. Results: The primary problems of locomotive projects in question are: electric power storage, in-depth modernization of the traction drive, and implementation of an optimal motion control algorithms in different modes. Increasing energy density stored in the traction battery, while reducing vehicle mass, ensures competitive advantages of eco-friendly hybrid locomotives versus traditional. The cost of the traction battery tends to dominate over the relevant economic parameters of other components of the traction drive hybrid locomotives, therefore, projects with a high technological level are relevant, while ensuring lower total weight of the vehicle. However, in the last decade, due to the increasing importance of electronic components in the transportation industry, along with the objectives stated above, problems of management optimization of rolling stock systems and provision of an appropriate level of quality control take center stage. Issues of energy storage application in the hybrid locomotive and their advantages over the currently used energy sources are considered in the article. Practical importance: It is shown that the use of a hybrid energy storage system will significantly increase the efficiency and reliability of the locomotive.

The Innovative Directions In Development And Implementations Of Hybrid Technologies In Surface Engineering

AbstractThe dynamics of the development of modern technology depends, to a great extent, on the possibilities of producing the innovative materials with high functionality parameters, which could be used in modern, highly advanced technological processes. Surface engineering plays a very important role in this area. This is mainly due to the fact that, for many structural materials, the possibilities of classical formation of their properties (e.g., by heat treatment or the selection of the microstructure, chemical and phase composition) have been practically used up. The material and technological achievements in the surface engineering area allow the modification of the properties of the surface layer of tool and machine components. As a result, they may be better suited to work in increasingly difficult and more demanding conditions. The hybrid technologies, combining several different methods of surface treatment in one complex technological process, are the most advanced solutions compared to already known surface engineering methods. In the article, the authors present the possibilities of shaping the functional properties of the surface layer. The authors describe problems associated with the development of the hybrid technology and provide the examples of physical modelling, design, technological development, and the practical application of a hybrid technology. In this work, the authors also identify the areas whose development is needed for more effective transfer of surface engineering innovations to business applications.

Experimental investigation of ultrasonic assisted pulse electrochemical drilling for INCONEL 718 with rotary tool

Electrochemical machining (ECM) is widely used for machining variety of components used in aerospace, automotive and defence applications. The study focuses on the development of hybrid technology in ultrasonically assisted pulse electrochemical machining (USA-PECM) using rotating tool.

Development of hybrid technology using E-beam and catalyst for aromatic VOCs control

A hybrid technology has been developed to control aromatic volatile organic compounds (VOCs) emission by annexing the catalyst technique with already existing electron beam (EB) technology. There is an increase in the removal efficiency and CO2 conversion rate as well as a decrease in by-product formation yield. When compared to EB–ceramic hybrid under the same existing EB-catalyst conditions, EB–catalyst hybrid has shown a 10% increase in efficiency in toluene treatment at approximately 10kGy. In the comparison study on the independent effect of EB-catalyst and catalyst itself, the removal efficiency with EB-catalyst revealed a 10% improvement in toluene treatment and an increase of 20% in styrene treatment. In addition, CO2 conversion rate also improved because there was a 55% increase in the generation of CO2 as well as a significant decrease in the by-products formation yield. Therefore, it is concluded that this technology will have a great effect on treating VOCs and odors.
