Box 10, 50728 Kuala Lumpur, Malaysia (E-mail [email protected] ) Received on March 5 ,2020 ABSTRACT: Comparatively, this review is meant to focus on possible developments studies of the rotary engine design. The controversial engine produces a direct rotational motion. Felix Wankel derived the triangular rotor shape from complex geometry of the Reuleaux triangle. The Wankel engine simulation and prediction of its performance is still limited. The current work reviews rotary engine’s flow field inside the combustion chamber with different commercial software used. It studies different parameters effect on the performance of the engine, such as the effect of the recess sizes and the shape-factor. It is found that the engine chambers design is one of the aspects of improvement opportunities. KEY WORDS: Rotary engine; Design geometry, Shape factor; Combustion simulation. [A1] The rotary engine recently got interests for possible 1. Introduction reliability as range extenders for electric vehicles. The rotary engine is reliable to be applied for the design architecture of UAV powertrains 12,13.

  • Gas Turbines in Simple Cycle and Combined Cycle Applications
    GAS TURBINES IN SIMPLE CYCLE & COMBINED CYCLE APPLICATIONS* Gas Turbines in Simple Cycle Mode Introduction The gas turbine is the most versatile item of turbomachinery today. It can be used in several different modes in critical industries such as power generation, oil and gas, process plants, aviation, as well domestic and smaller related industries. A gas turbine essentially brings together air that it compresses in its compressor module, and fuel, that are then ignited. Resulting gases are expanded through a turbine. That turbine’s shaft continues to rotate and drive the compressor which is on the same shaft, and operation continues. A separate starter unit is used to provide the first rotor motion, until the turbine’s rotation is up to design speed and can keep the entire unit running. The compressor module, combustor module and turbine module connected by one or more shafts are collectively called the gas generator. The figures below (Figures 1 and 2) illustrate a typical gas generator in cutaway and schematic format. Fig. 1. Rolls Royce RB211 Dry Low Emissions Gas Generator (Source: Process Plant Machinery, 2nd edition, Bloch & Soares, C. pub: Butterworth Heinemann, 1998) * Condensed extracts from selected chapters of “Gas Turbines: A Handbook of Land, Sea and Air Applications” by Claire Soares, publisher Butterworth Heinemann, BH, (for release information see www.bh.com) Other references include Claire Soares’ other books for BH and McGraw Hill (see www.books.mcgraw-hill.com) and course notes from her courses on gas turbine systems.

It was founded in 1978 as a special division of the Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) GmbH. GATE is a centre for the dissemination and promotion of appropriate technologies for developing countries. GATE defines "Appropriate technologies" as those which are suitable and acceptable in the light of economic social and cultural criteria. They should contribute to socio-economic development whilst ensuring optimal utilization of resources and minimal detriment to the environment. Depending on the case at hand a traditional, intermediate or highly-developed can be the "appropriate" one. GATE focusses its work on three key areas: - Dissemination of Appropriate Technologies: Collecting, processing and disseminating information on technologies appropriate to the needs of the developing countries; ascertaining the technological requirements of Third World countries; support in the form of personnel material and equipment to promote the development and adaptation of technologies for developing countries. - Research and Development: Conducting and/or promoting research and development work in appropriate technologies. - Environmental Protection: The growing

  • The Development of the Single Sleeve Valve Two-Stroke Engine Over the Last 110 Years
    energies Review The Silent Path: The Development of the Single Sleeve Valve Two-Stroke Engine over the Last 110 Years Robert Head * and James Turner Mechanical Engineering, Faculty of Engineering and Design, University of Bath, Bath BA2 7AY, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-0789-561-7437 Abstract: At the beginning of the 20th century the operational issues of the Otto engine had not been fully resolved. The work presented here seeks to chronicle the development of one of the alternative design pathways, namely the replacement for the gas exchange mechanism of the more conventional poppet valve arrangement with that of a sleeve valve. There have been several successful engines built with these devices, which have a number of attractive features superior to poppet valves. This review moves from the initial work of Charles Knight, Peter Burt, and James McCollum, in the first decade of the 20th century, through the work of others to develop a two-stroke version of the sleeve- valve engine, which climaxed in the construction of one of the most powerful piston aeroengines ever built, the Rolls-Royce Crecy. After that period of high activity in the 1940s, there have been limited further developments. The patent efforts changed over time from design of two-stroke sleeve-drive mechanisms through to cylinder head cooling and improvements in the control of the thermal expansion of the relative components to improve durability. These documents provide a foundation for a design of an internal combustion engine with potentially high thermal efficiency. Keywords: two-stroke; sleeve valves; patents Citation: Head, R.; Turner, J.

    2018 NDIA GROUND VEHICLE SYSTEMS ENGINEERING AND TECHNOLOGY SYMPOSIUM POWER & MOBILITY (P&M) TECHNICAL SESSION AUGUST 7-9, 2018 - NOVI, MICHIGAN COMPACT, LIGHTWEIGHT, HIGH EFFICIENCY ROTARY ENGINE FOR GENERATOR, APU, AND RANGE-EXTENDED ELECTRIC VEHICLES Alexander Shkolnik, PhD, Nikolay Shkolnik, PhD Jeff Scarcella, Mark Nickerson Alexander Kopache, Kyle Becker Michael Bergin, PhD, Adam Spitulnik Rodrigo Equiluz, Ryan Fagan Saad Ahmed, Sean Donnelly, Tiago Costa LiquidPiston, Inc. Bloomfield, CT ABSTRACT Today automotive gasoline combustion engine’s are relatively inefficient. Diesel engines are more efficient, but are large and heavy, and are typically not used for hybrid electric applications. This paper presents an optimized thermodynamic cycle dubbed the High Efficiency Hybrid Cycle, with 75% thermodynamic efficiency potential, as well as a new rotary ‘X’ type engine architecture that embodies this cycle efficiently and compactly, while addressing the challenges of prior Wankel-type rotary engines, including sealing, lubrication, durability, and emissions. Preliminary results of development of a Compression Ignited 30 kW X engine targeting 45% (peak) brake thermal efficiency are presented. This engine aims to fit in a 10” box, with a weight of less than 40 lb, and could efficiently charge a battery to extend the range of an electric vehicle. INTRODUCTION in Figure 1, and will describe the development Today’s Diesel / heavy-fueled engines, while status of the X4, a .8L Compression Ignition relatively efficient, are large and heavy, with a power-to-weight ratio of approximately .1-.2 hp/lb (see, e.g., [12]). This paper presents a new type of rotary Diesel combustion engine architecture (the “X Engine”), which is based on an optimized thermodynamic cycle: the High Efficiency Hybrid Cycle (HEHC).
