Book excerpt: This thesis deals with the design of a single cylinder high-speed spark ignition linear engine with a spring system return cycle. The main objective of the research is to design and analyse a free piston linear engine that is easy to start, easy to maintain and easy to control. The unique design of the spring as a return cycle in a free piston linear engine is presented and its effects on engine performance and motion are discussed. The engine performance has been predicted the aim is to design a linear engine particularly for the spring system. The spring design has been optimised by using a multilevel optimization approach. Based on the optimisation of the spring design, the linear engine geometry design has been conducted. The performance of the linear engine design has been measured and the results compared with the predicted performance. Besides which the motion of the linear engine has been studied; however, friction affect show the rotated of the piston. It is necessary to modify the spring mechanism to ensure that the scavenging process works properly. Two scenarios such as the removal of the bottom part of the piston skirt and adding a lock to the connecting rod are recommended, based of structural stress and thermal-structural stress analysis. Software has been used in the research to analyse the design of the free piston linear engine with a spring system, including GT-Power, SolidWorks, Matlab, Algor, and Spread-Sheet. The model has been built using GT-Power to predict the engine performance. To validate the model, it has been assessed with the original engine manual and experimentally. Three step multilevel optimisation of the spring geometry has been carried out by using Matlab and Spread-Sheet. SolidWorks has been used to design all of the components and for the assembly of the linear engine. Cosmos motion, which is a part of the SolidWorks facility, has been used to analyse the piston dynamics of the linear engine. Once again, GT-Power has been used to analyse the effect of the spring design on the linear engine performance. For the modification of the design of the spring system, Algor has been used to analyse the thermal-structural stress of the piston and the connecting rod. Through step by step considerations started from building model to predict the performance of linear engine, to optimize the spring geometry design then continued build the free piston linear engine with spring system including design, analyses and modified. The result is a design which predicts the performance and the dynamics of piston motion. Only 50% of the 12 speeds sampled worked correctly. The rotation of the piston on the Z-ordinate can be fixed through modification of the piston or connecting rod. A design of a single cylinder high-speed spark ignition linear engine with spring system as return cycle has been carried out. Although the range of speeds was narrow compared to a conventional engine, the maximum power output is still higher. The final design result was 1.03 kW at 3.6 m/sec.

This book was released on 2023-02-22 with total page 214 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.

Available in PDF, EPUB and Kindle. Book excerpt: Twentyfour years have gone by since the publication of K. Lohner and H. Muller's comprehen sive work "Gemischbildung und Verbrennung im Ottomotor" in 1967 [1.1]' Naturally, the field of mixture formation and combustion in the spark-ignition engine has wit nessed great technological advances and many new findings in the intervening years, so that the time seemed ripe for presenting a summary of recent research and developments. There fore, I gladly took up the suggestion of the editors of this series of books, Professor Dr. H. List and Professor Dr. A. Pischinger, to write a book summarizing the present state of the art. A center of activity of the Institute of Internal-Combustion Engines and Automotive Engineering at the Vienna Technical University, which I am heading, is the field of mixture formation -there fore, many new results that have been achieved in this area in collaboration with the respective industry have been included in this volume. The basic principles of combustion are discussed only to that extent which seemect necessary for an understanding of the effects of mixture formation. The focal point of this volume is the mixture formation in spark-ignition engines, covering both the theory and actual design of the mixture formation units and appropriate intake manifolds. Also, the related measurement technology is explained in this work.

This book was released on 2012-12-06 with total page 407 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 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination 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 con cerned if the printing and distribution of the volumes were handled by an interna tional 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 Cor poration 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 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2011 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Full engine control can only be accomplished with multi-input multi-output (MIMO) control system requiring measurement of variables for which no sensor/instrument is yet available in the Renewable Energy and Engines Laboratory, therefore a less detailed single input single output (SISO) engine model is developed. To develop the engine controller a model of the engine had to first be determined. Known Discrete-Event and Mean-Value models were the first choice, but could not be utilized because of the nature of the single cylinder intake manifold pressure. Therefore an engine model based on experimental data had to be developed. Using Matlab/ Simulink, xPC Target and data acquisition hardware a model of the single cylinder engine was developed. These models were developed by taking measurements of the engines dynamics such as engine speed, crank angle, air mass intake, spark timing, injection timing, and intake temperatures at different engine speed set points while running gasoline and then a gasoline and ethanol mix (E85). From which experimental coefficients were determined necessary for the model.
