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.

Download or read book Assessment of Fuel Economy Technologies for Light-Duty Vehicles written by National Research Council and published by National Academies Press. 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 2014 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internal combustion (IC) engines are vital components of today's automotive industry. They use few of the most complex operating principles and processes. Over the past few decades, there has been an ever increasing demand for top notch vehicle efficiency and performance. The detailed working knowledge of internal combustion engines has thus been a point of interest for many researchers. IC engines basically convert the chemical energy of fluids into mechanical output, by means of a process called combustion. In four-stroke, spark ignition IC engines, ideal pressure-volume diagram is given by the OTTO cycle, which basically gives pressures inside the engine cylinder with respect to piston position. Thus, in order to study combustion, measurement of in-cylinder pressure is a critical task. In this project, a test setup is created, with a single cylinder SI engine being tested. A high pressure spark plug sensor is used to measure pressures inside the engine cylinder. An optical crank angle encoder is mounted on the engine crankshaft to measure accurate crank rotation angle. The objective of the project is to obtain an accurate real time pressure vs. crank angle diagram, which in turn can lead to pressure vs. volume diagram. The changes in the pressure are studied under the effect of various engine parameters. A high capacity system from National Instruments is used for data acquisition purposes. A LabVIEW program is developed from scratch to measure, acquire and write the data. Real time plots of pressure vs crank angle, pressure vs volume can be seen on the LabVIEW front panel. It is observed that the obtained results match with the theoretical representations of the ideal air standard Otto cycle.

Download or read book Modeling and Control of Engines and Drivelines written by Lars Eriksson and published by John Wiley & Sons. This book was released on 2014-04-07 with total page 589 pages. 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 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.
