Book Mixture Formation in Internal Combustion Engines

Download or read book Mixture Formation in Internal Combustion Engines written by Carsten Baumgarten and published by Springer Science & Business Media. This book was released on 2006-09-28 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic control of mixture formation with modern high-pressure injection systems enables us to achieve considerable improvements of the combustion pr- ess in terms of reduced fuel consumption and engine-out raw emissions. However, because of the growing number of free parameters due to more flexible injection systems, variable valve trains, the application of different combustion concepts within different regions of the engine map, etc., the prediction of spray and m- ture formation becomes increasingly complex. For this reason, the optimization of the in-cylinder processes using 3D computational fluid dynamics (CFD) becomes increasingly important. In these CFD codes, the detailed modeling of spray and mixture formation is a prerequisite for the correct calculation of the subsequent processes like ignition, combustion and formation of emissions. Although such simulation tools can be viewed as standard tools today, the predictive quality of the sub-models is c- stantly enhanced by a more accurate and detailed modeling of the relevant pr- esses, and by the inclusion of new important mechanisms and effects that come along with the development of new injection systems and have not been cons- ered so far. In this book the most widely used mathematical models for the simulation of spray and mixture formation in 3D CFD calculations are described and discussed. In order to give the reader an introduction into the complex processes, the book starts with a description of the fundamental mechanisms and categories of fuel - jection, spray break-up, and mixture formation in internal combustion engines.

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 Simulating Combustion

Download or read book Simulating Combustion written by Günter P. Merker and published by Springer Science & Business Media. This book was released on 2005-12-17 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The numerical simulation of combustion processes in internal combustion engines, including also the formation of pollutants, has become increasingly important in the recent years, and today the simulation of those processes has already become an indispensable tool when - veloping new combustion concepts. While pure thermodynamic models are well-established tools that are in use for the simulation of the transient behavior of complex systems for a long time, the phenomenological models have become more important in the recent years and have also been implemented in these simulation programs. In contrast to this, the thr- dimensional simulation of in-cylinder combustion, i. e. the detailed, integrated and continuous simulation of the process chain injection, mixture formation, ignition, heat release due to combustion and formation of pollutants, has been significantly improved, but there is still a number of challenging problems to solve, regarding for example the exact description of s- processes like the structure of turbulence during combustion as well as the appropriate choice of the numerical grid. While chapter 2 includes a short introduction of functionality and operating modes of internal combustion engines, the basics of kinetic reactions are presented in chapter 3. In chapter 4 the physical and chemical processes taking place in the combustion chamber are described. Ch- ter 5 is about phenomenological multi-zone models, and in chapter 6 the formation of poll- ants is described.

Book Cycle Analysis of Fuel inducted Internal Combustion Engine for Efficient Optimization of Engine Design Configurations and Performance

Download or read book Cycle Analysis of Fuel inducted Internal Combustion Engine for Efficient Optimization of Engine Design Configurations and Performance written by Brian Peter Murphy and published by . This book was released on 2005 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 1-Dimensional computer code was developed to predict the performance of an engine. The code is written in FORTRAN, and can be used to predict engine performance for automotive and racing applications. It can predict in-cylinder temperature, gas pressure, and heat transfer coefficients as a function of crank angle; as well as a variable specific heat calculation throughout the cycle. The turbulent flame intensity varies across the RPM span and was formulated based on a correlation study of the computer code and dynamometer data results. In-cylinder wall temperatures are determined based on influences of air-fuel ratio, compression ratio, spark timing, and coolant temperature. In the event of auto-ignition or knock occurring, the tendency for this to happen is also calculated and is shown in the output data set. To optimize engine performance of an engine for racing applications and provide an experimental database for the numerical code validation, a test program was developed. The engine selected was a 1973 Big Block Chevrolet (BBC) engine. The simulation program can calculate engine's performance in a matter of seconds, saving weeks and months of dynamometer testing as well as large sums of money. With the use of minimal computer requirements, an accurate simulation can be predicted within a very short period of time. The computer simulation proved to be effective in varying coolant temperatures and ignition timing, with small errors induced for varying air-fuel ratios.

Book Assessment of Fuel Economy Technologies for Light Duty Vehicles

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.
