Book Nonlinear Systems and Circuits in Internal Combustion Engines

Download or read book Nonlinear Systems and Circuits in Internal Combustion Engines written by Ferdinando Taglialatela-Scafati and published by Springer. This book was released on 2017-10-31 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief provides an overview on the most relevant nonlinear phenomena in internal combustion engines with a particular emphasis on the use of nonlinear circuits in their modelling and control. The brief contains advanced methodologies —based on neural networks and soft-computing approaches among others— for the compensation of engine nonlinearities by using the combustion pressure signal and proposes several techniques for the reconstruction of this signal on the basis of different engine parameters, including engine-block vibration and crankshaft rotational speed. Another topic of the book is the diagnosis of the nonlinearities of injection systems and their balancing, which is a mandatory task for the new generation of gasoline direct injection engines. The authors come from both industrial and academic backgrounds, so the brief represents an important tool both for researchers and practitioners in the automotive industry.

Book Introduction to Modeling and Control of Internal Combustion Engine Systems

Download or read book Introduction to Modeling and Control of Internal Combustion Engine Systems written by Lino Guzzella and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 303 pages. Available in PDF, EPUB and Kindle. 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.

Book Estimation of Cylinder Wise Combustion Features with Combined Processing of Engine Speed and Cylinder Pressure Regarding Torsional Deflections of the Crankshaft

Download or read book Estimation of Cylinder Wise Combustion Features with Combined Processing of Engine Speed and Cylinder Pressure Regarding Torsional Deflections of the Crankshaft written by Christoph Kallenberger and published by Logos Verlag Berlin GmbH. This book was released on 2008 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rising fuel prices, stricter emission standards, as well as the increasing demands from consumers for driving comfort, all motivate the rapid development and improvement of combustion engine control systems. New concepts, such as variable valve timing systems, downsizing in combination with supercharging systems and new injection systems bring significant advantages for engines, however they result in increased system complexity. In order to provide optimal operating conditions for these concepts, advanced control and diagnosis strategies are necessary. They require feedback information from the combustion chamber. The in-cylinder pressure has a close relationship to the thermodynamics of a combustion and, consequently, is suited to this purpose. In-cylinder pressure sensors are already widely used in today's research engine test beds. However, a fully-equipped engine with pressure sensors is too expensive for series production. This motivates this work to investigate a cost efficient approach using only one in-cylinder pressure sensor in combination with the engine speed sensor. The engine speed signal contains the cylinder-wise combustion information and is measured at the crankshaft. Torsional defections at the crankshaft distort the engine speed signal. This work shows how to compensate this effect in order to provide highly accurate combustion features for engine control and diagnosis.

Book AIR CHARGE ESTIMATION FOR AN SI ENGINE USING IN CYLINDER PRESSURE SENSOR

Download or read book AIR CHARGE ESTIMATION FOR AN SI ENGINE USING IN CYLINDER PRESSURE SENSOR written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : An accurate estimation of cycle by cycle in-cylinder mass and the composition of the combustion chamber charge is required for engine control strategies to meet stringent pollution emission and fuel consumption regulations. Estimation of fresh charge and residual gas masses is beneficial in terms of fuel efficiency, tailpipe emissions, engine performance, for engine control strategies. Air-flow meter, which is mounted in the intake air circuit, can be utilized in a closed-loop strategy to control air charge. However, air flow meter has a response delay; moreover dynamics of intake manifold and pipes must be taken into consideration to improve the estimation of air charge and accurate feedback in transients. As an alternative to air flow meter, in-cylinder pressure sensors can be utilized to directly measure cylinder pressure, based on which, the amount of air charge can be estimated without the requirement to model the dynamics of the manifold. In this work, an air charge estimation algorithm is proposed, which uses cylinder pressure trace data at specific cycle events, and by applying thermodynamics and heat transfer relationships, estimates individual cylinder air charge for each cycle in different test conditions. A residual gas estimator, which can be applied online, is also incorporated in the algorithm to estimate residual gas mass for each cycle. Estimator output is validated and calibrated based on experimental setup air charge, which is calculated from the amount of injected fuel in each cylinder and individual wide-band sensor data. Uncertainty propagation analysis is performed to investigate the uncertainty in estimated air charge based on the uncertainties in measured and model parameters. This analysis reveals the information about the parameters with major contribution to the uncertainty in estimated air charge.
