This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 2011-06-03 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various combinations of commercially available technologies could greatly reduce fuel consumption in passenger cars, sport-utility vehicles, minivans, and other light-duty vehicles without compromising vehicle performance or safety. Assessment of Technologies for Improving Light Duty Vehicle Fuel Economy estimates the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition diesel, and hybrid. According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29 percent at an additional cost of $2,200 to the consumer. Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37 percent at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43 percent at an increase of $6,000 per vehicle. The book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. In contrast, fuel economy measures how far a vehicle will travel with a gallon of fuel. Because fuel consumption data indicate money saved on fuel purchases and reductions in carbon dioxide emissions, the book finds that vehicle stickers should provide consumers with fuel consumption data in addition to fuel economy information.

This book was released on 2000-02-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process of fuel injection, spray atomization and vaporization, charge cooling, mixture preparation and the control of in-cylinder air motion are all being actively researched and this work is reviewed in detail and analyzed. The new technologies such as high-pressure, common-rail, gasoline injection systems and swirl-atomizing gasoline fuel injections are discussed in detail, as these technologies, along with computer control capabilities, have enabled the current new examination of an old objective; the direct-injection, stratified-charge (DISC), gasoline engine. The prior work on DISC engines that is relevant to current GDI engine development is also reviewed and discussed. The fuel economy and emission data for actual engine configurations have been obtained and assembled for all of the available GDI literature, and are reviewed and discussed in detail. The types of GDI engines are arranged in four classifications of decreasing complexity, and the advantages and disadvantages of each class are noted and explained. Emphasis is placed upon consensus trends and conclusions that are evident when taken as a whole; thus the GDI researcher is informed regarding the degree to which engine volumetric efficiency and compression ratio can be increased under optimized conditions, and as to the extent to which unburned hydrocarbon (UBHC), NOx and particulate emissions can be minimized for specific combustion strategies. The critical area of GDI fuel injector deposits and the associated effect on spray geometry and engine performance degradation are reviewed, and important system guidelines for minimizing deposition rates and deposit effects are presented. The capabilities and limitations of emission control techniques and after treatment hardware are reviewed in depth, and a compilation and discussion of areas of consensus on attaining European, Japanese and North American emission standards presented. All known research, prototype and production GDI engines worldwide are reviewed as to performance, emissions and fuel economy advantages, and for areas requiring further development. The engine schematics, control diagrams and specifications are compiled, and the emission control strategies are illustrated and discussed. The influence of lean-NOx catalysts on the development of late-injection, stratified-charge GDI engines is reviewed, and the relative merits of lean-burn, homogeneous, direct-injection engines as an option requiring less control complexity are analyzed.

With low computational costs, it can optimize the design and operation of spark ignition engines as well as it allows to analyze cycle-to-cycle fluctuations. Including details about the structure of a complete simulation scheme, information about what kind of information can be obtained, and comparisons of the simulation results with experiments, Introduction to Quasi-dimensional Simulation of Spark Ignition Engines offers a thorough guide of this technique. Advanced undergraduates and postgraduates as well as researchers in government and industry in all areas related to applied physics and mechanical and automotive engineering can apply these tools to simulate cyclic variability, potentially leading to new design and control alternatives for lowering emissions and expanding the actual operation limits of spark ignition engines
Download or read book Injection Technologies and Mixture Formation Strategies For Spark Ignition and Dual Fuel Engines written by Alessandro Ferrari and published by SAE International. This book was released on 2022-06-24 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuel injection systems and performance is fundamental to combustion engine performance in terms of power, noise, efficiency, and exhaust emissions. There is a move toward electric vehicles (EVs) to reduce carbon emissions, but this is unlikely to be a rapid transition, in part due to EV batteries: their size, cost, longevity, and charging capabilities as well as the scarcity of materials to produce them. Until these isssues are resolved, refining the spark-ignited engine is necessary address both sustainability and demand for affordable and reliable mobility. Even under policies oriented to smart sustainable mobility, spark-ignited engines remain strategic, because they can be applied to hybridized EVs or can be fueled with gasoline blended with bioethanol or bio-butanol to drastically reduce particulate matter emissions of direct injection engines in addition to lower CO2 emissions. In this book, Alessandro Ferrari and Pietro Pizzo provide a full review of spark-ignited engine fuel injection systems. The most popular typologies of fuel injection systems are considered, with special focus on state-of-the-art solutions. Dedicated sections on the methods for air mass evaluation, fuel delivery low-pressure modules, and the specific subsystems for idle, cold start, and warm-up control are also included. The authors pay special attention to mixture formation strategies, as they are a fundamental theme for SI engines. An exhaustive overview of fuel injection technologies is provided, and mixture formation strategies for spark ignited combustion engines are considered. Fuel Injection Systems illustrates the performance of these systems and will also serve as a reference for engineers who are active in the aftermarket, offering detailed information on fuel injection system solutions that are mounted in older vehicles.

Download or read book Spark Ignition Engine Modeling and Control System Design written by Amir-Mohammad Shamekhi and published by CRC Press. This book was released on 2023-02-22 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a step-by-step guide to the engine control system design, providing case studies and a thorough analysis of the modeling process using machine learning, and model predictive control (MPC). Covering advanced processes alongside the theoretical foundation, MPC enables engineers to improve performance in both hybrid and non-hybrid vehicles. Control system improvement is one of the major priorities for engineers seeking to enhance an engine. Often possible on a low budget, substantial improvements can be made by applying cutting-edge methods, such as artificial intelligence when modeling engine control system designs and using MPC. This book presents approaches to control system improvement at mid, low, and high levels of control. Beginning with the model-in-the-loop hierarchical control design of ported fuel injection SI engines, this book focuses on optimal control of both transient and steady state and also discusses hardware-in-the-loop. The chapter on low-level control discusses adaptive MPC and adaptive variable functioning, as well as designing a fuel injection feed-forward controller. At mid-level control, engine calibration maps are discussed, with consideration of constraints such as limits on pollutant emissions. Finally, the high-level control methodology is discussed in detail in relation to transient torque control of SI engines. This comprehensive yet clear guide to control system improvement is an essential read for any engineer working in automotive engineering and engine control system design.

Download or read book The Performance and Emissions Characteristics of Heavy Fuels in a Small Spark Ignition Engine written by Jon-Russell J. Groenewegen and published by . This book was released on 2011 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis research was conducted in pursuit of the DoD's plan for the universal use of a heavy, low volatility hydrocarbon fuel, and the increased interest in bio-derived fuels for small Unmanned Aircraft Systems (UAS's). Currently a majority of small UAS's use small spark ignition engines for their high power densities. Typically, these systems use commercial off-the-shelf power plants that are not optimized for fuel efficiency. Increased fuel efficiency is being pursued alongside the ability to utilize military heavy fuels. A test stand using a 33.5 cc four-stroke, spark ignition, air-cooled, single cylinder engine was constructed. Research was conducted to establish the feasibility of converting the existing system to utilize JP-8 with the stock mechanical carburetion. The stock carburetion had difficulty maintaining a consistent air/fuel ratio across the entire engine operating range. To resolve this, an electronic fuel injection system was developed to gain greater control over fuel mixture. An air-assisted electronic fuel injector was sourced from a scooter and adapted to work with the 33.5cc four-stroke engine. An aluminum injector mount was designed and machined and electronic controls were employed. Sensors on the valvetrain and crankshaft were developed as control signals for the injection system. The injector was characterized for flow rates and droplet size. The test stand consisted of a small dynamometer coupled to the engine. Servo throttle actuation was designed and throttle position was monitored with a throttle position sensor. The air-assisted injector was supplied with regulated shop air, and the fuel pressurized using regulated nitrogen. A fuel flowmeter and mass air flowmeter monitored equivalence ratio. Work was done to facilitate smooth measurement of unsteady air flow intrinsic to single-cylinder engines. Performance testing showed a decrease in brake specific fuel consumption (BSFC) while utilizing the injection system for the baseline fuel (Avgas 100LL), as greater mixture control (closer to stoichiometric) was realized. The engine was started using gasoline. Heavy fuel testing showed the ability to achieve required torque values at certain engine speeds. JP-8 was tested on the carbureted engine and fuel injected engine, showing a decrease in BSFC over baseline (carbureted avgas) with the carburetor and a further decrease in BSFC for the injected system. Biofuels that were tested were plant-based Camelina (carbureted and injected) and a UDRI grown and extracted algae-based fatty acid methyl ester (FAME) biofuel blended with D2 diesel in a 20% algae/80% diesel blend. Performance results for the Camelina showed a decrease in BSFC for the carbureted engine and the largest decrease of all the test fuels for the injected Camelina fuel. The algae blend showed less decrease in BSFC than the 100% diesel fuel. Emissions data were recorded as well. The injection system demonstrated less CO emissions for the injected fuels over the carbureted fuels due to closer to stoichiometric mixtures. Similarly, unburned hydrocarbon emissions decreased when injection was employed. NOx emissions were higher for the fuel injected engine, as peak NOx emissions will typically occur at slightly lean conditions and the injected fuels were closer to peak NOx emission conditions.

This book was released on 1964 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The RAM vee-4, two-stroke stratified charge engine is a spark-ignition, blown, pressure lubricated, port valve engine with a cam actuated auxiliary air inlet poppet valve. It is designed to operate with lean air-fuel ratios, like a compression-ignition engine, but with a low compression ration and spark ignition. No carburetor is employed. Either timed or continuous manifold fuel injection upstream from the auxiliary valve may be used. The tests reported here are for continuous injection. Valve timing had the most pronounced effect on hydrocarbon emissions, followed by auxiliary-air pressure. Spark timing, oil temperature and jacket water temperature also influenced the emissions but to a lesser extent. These adjustments also affected the specific fuel consumption. Generally an adjustment which reduced the air-fuel ratio also reduced the hydrocarbons. The current data suggest that timed fuel injection in place of continuous injection may result in a further significant reduction of hydrocarbons in the exhaust. (Author).
