Book Synopsis Cycle Analysis of Fuel-inducted Internal Combustion Engine for Efficient Optimization of Engine Design Configurations and Performance by : Brian Peter Murphy

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. This book was released on 2005. 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 Synopsis Computational Optimization of Internal Combustion Engines by : Yu Shi

Download or read book Computational Optimization of Internal Combustion Engines written by Yu Shi. This book was released on 2011-06-22. Available in PDF, EPUB and Kindle. Book excerpt: Computational Optimization of Internal Combustion Engines presents the state of the art of computational models and optimization methods for internal combustion engine development using multi-dimensional computational fluid dynamics (CFD) tools and genetic algorithms. Strategies to reduce computational cost and mesh dependency are discussed, as well as regression analysis methods. Several case studies are presented in a section devoted to applications, including assessments of: spark-ignition engines, dual-fuel engines, heavy duty and light duty diesel engines. Through regression analysis, optimization results are used to explain complex interactions between engine design parameters, such as nozzle design, injection timing, swirl, exhaust gas recirculation, bore size, and piston bowl shape. Computational Optimization of Internal Combustion Engines demonstrates that the current multi-dimensional CFD tools are mature enough for practical development of internal combustion engines. It is written for researchers and designers in mechanical engineering and the automotive industry.

Book Synopsis Internal Combustion Engines by : Colin R. Ferguson

Download or read book Internal Combustion Engines written by Colin R. Ferguson. This book was released on 2015-07-07. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the Second Edition in 2001, there have been considerable advances and developments in the field of internal combustion engines. These include the increased importance of biofuels, new internal combustion processes, more stringent emissions requirements and characterization, and more detailed engine performance modeling, instrumentation, and control. There have also been changes in the instructional methodologies used in the applied thermal sciences that require inclusion in a new edition. These methodologies suggest that an increased focus on applications, examples, problem-based learning, and computation will have a positive effect on learning of the material, both at the novice student, and practicing engineer level. This Third Edition mirrors its predecessor with additional tables, illustrations, photographs, examples, and problems/solutions. All of the software is ‘open source’, so that readers can see how the computations are performed. In addition to additional java applets, there is companion Matlab code, which has become a default computational tool in most mechanical engineering programs.
