Book excerpt: Internal combustion engines still have a potential for substantial improvements, particularly with regard to fuel efficiency and environmental compatibility. These goals can be achieved with help of control systems. Modeling and Control of Internal Combustion Engines (ICE) addresses these issues by offering an introduction to cost-effective model-based control system design for ICE. The primary emphasis is put on the ICE and its auxiliary devices. Mathematical models for these processes are developed in the text and selected feedforward and feedback control problems are discussed. The appendix contains a summary of the most important controller analysis and design methods, and a case study that analyzes a simplified idle-speed control problem. The book is written for students interested in the design of classical and novel ICE control systems.

Download or read book A Global Reaction Mechanism for Transient Simulations of Three-Way Catalytic Converters written by Raoul Holder and published by Cuvillier Verlag. This book was released on 2008-09-04 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complex interactions between chemical kinetics and transport phenomena of mass, momentum and energy lead to incomplete fuel combustion, which is the origin of pollutant formation of internal combustion engines. Vehicle exhaust gas emission control devices have continuously been improved to meet the constantly tightened standards. Three-way catalyst technology is extensively used for the purification of automotive exhaust gases, usually in combination with monolithic (honeycomb) reactors. A promising alternative to the time consuming and costly engine and vehicle experiments are catalytic reactor model. In this work a global reaction mechanism for three-way catalysts is developed including 16 reactions and 12 gas phase species. The reaction mechanism is combined with an empirical oxygen storage model and validated against a number of different real engine experiments carried out on both fresh (not aged) and aged catalysts. Once the mechanism is validated against the fresh system, the adaption to the aged system is achieved solely by the reduction of the available reactive surface area of the washcoat, without tuning the individual reaction parameters. Finally the parameter set of the aged system is used to simulate a FTP75 drive cycle and the results are compared to experimental data of the same catalyst without further tuning. First a transient one-dimensional catalyst model is derived in chapter 2. First a short introduction to the structure of monolithic reactors is given, followed by the introduction of the governing equations for catalytically reacting flows. Chapter 3 focuses on the relevant transport processes inside the monolithic reactor channel and the adequacy of the transport models applied here. Local distributions of Nusselt and Sherwood numbers inside a monolith channel are resolved using a two-dimensional model. The cases of non-reacting and reacting conditions at the channel wall are discussed and subsequently compared to according a priori correlations. The subject of chapter 4 is the development and validation of the reaction mechanism. An advanced multi-objective optimization algorithm is used to calibrate the kinetic parameters of the presented reaction mechanism (comprising 16 reactions) to match the conversion behavior of a fresh catalyst. The simulation results are compared with experimental data at different operating conditions. In a second step the kinetic model is then used to simulate the conversion behavior of an aged catalyst. The adaption of the kinetic model is achieved only by the reduction of the available surface area. Again the computed conversion characteristics are compared to measured data. Finally an empirical oxygen storage model is included. In chapter 5 the catalyst model for the aged system is used to predict the tailpipe emissions during real drive cycle conditions. Finally a catalyst design parameter study is presented as a typical application of the model within the development process of exhaust gas aftertreatment systems.

Download or read book Nonlinear Control Under Nonconstant Delays written by Nikolaos Bekiaris-Liberis and published by SIAM. This book was released on 2013-09-25 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have developed a methodology for control of nonlinear systems in the presence of long delays, with large and rapid variation in the actuation or sensing path, or in the presence of long delays affecting the internal state of a system. In addition to control synthesis, they introduce tools to quantify the performance and the robustness properties of the designs provided in the book. The book is based on the concept of predictor feedback and infinite-dimensional backstepping transformation for linear systems and the authors guide the reader from the basic ideas of the concept?with constant delays only on the input?all the way through to nonlinear systems with state-dependent delays on the input as well as on system states. Readers will find the book useful because the authors provide elegant and systematic treatments of long-standing problems in delay systems, such as systems with state-dependent delays that arise in many applications. In addition, the authors give all control designs by explicit formulae, making the book especially useful for engineers who have faced delay-related challenges and are concerned with actual implementations and they accompany all control designs with Lyapunov-based analysis for establishing stability and performance guarantees.

Available in PDF, EPUB and Kindle. Book excerpt: Control systems have come to play an important role in the performance of modern vehicles with regards to meeting goals on low emissions and low fuel consumption. To achieve these goals, modeling, simulation, and analysis have become standard tools for the development of control systems in the automotive industry. Modeling and Control of Engines and Drivelines provides an up-to-date treatment of the topic from a clear perspective of systems engineering and control systems, which are at the core of vehicle design. This book has three main goals. The first is to provide a thorough understanding of component models as building blocks. It has therefore been important to provide measurements from real processes, to explain the underlying physics, to describe the modeling considerations, and to validate the resulting models experimentally. Second, the authors show how the models are used in the current design of control and diagnosis systems. These system designs are never used in isolation, so the third goal is to provide a complete setting for system integration and evaluation, including complete vehicle models together with actual requirements and driving cycle analysis. Key features: Covers signals, systems, and control in modern vehicles Covers the basic dynamics of internal combustion engines and drivelines Provides a set of standard models and includes examples and case studies Covers turbo- and super-charging, and automotive dependability and diagnosis Accompanied by a web site hosting example models and problems and solutions Modeling and Control of Engines and Drivelines is a comprehensive reference for graduate students and the authors’ close collaboration with the automotive industry ensures that the knowledge and skills that practicing engineers need when analysing and developing new powertrain systems are also covered.

This book was released on 2001-12-16 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions inspection and maintenance (I/M) programs subject vehicles to periodic inspections of their emission control systems. Despite widespread use of these programs in air-quality management, policy makers and the public have found a number of problems associated with them. Prominent among these issues is the perception that emissions benefits and other impacts of I/M programs have not been evaluated adequately. Evaluating Vehicle Emissions Inspection and Maintenance Programs assesses the effectiveness of these programs for reducing mobile source emissions. In this report, the committee evaluates the differences in the characteristics of motor vehicle emissions in areas with and without I/M programs, identifies criteria and methodologies for their evaluation, and recommends improvements to the programs. Most useful of all, this book will help summarize the observed benefits of these programs and how they can be redirected in the future to increase their effectiveness.
