Book excerpt: The objective of this project is to address the problems identified in order to obtain the data-base covering performance, operational characteristics and emissions essential for making a rational decision regarding the selection and design of prototype hydrogen-fueled, air-breathing engines capable of being manufactured for general automotive use. The project program plan calls for investigation of pre-intake valve closing fuel ingestion (Pre IVC) hydrogen-fueled engines during the first two of the three year project. With Pre IVC engines the fuel is introduced into the combustion chamber prior to closing of the intake valve. This is in contrast to Post IVC engines in which fuel is introduced in the cylinder after the intake valve closes. Post IVC engines are to be investigated during the third year according to the project program plan. This quarterly report is a summary of the work accomplished during the first three months of the project.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in a 3 year research program to evaluate the performance and emission characteristics of hydrogen-fueled internal combustion engines is reported. Fifteen hydrogen engine configurations will be subjected to performance and emissions characterization tests. During the first two years, baseline data for throttled and unthrottled, carburetted and timed hydrogen induction, Pre IVC hydrogen-fueled engine configurations, with and without exhaust gas recirculation (EGR) and water injection, were obtained. These data, along with descriptions of the test engine and its components, the test apparatus, experimental techniques, experiments performed and the results obtained, are given. Analyses of other hydrogen-engine project data are also presented and compared with the results of the present effort. The unthrottled engine vis-a-vis the throttled engine is found, in general, to exhibit higher brake thermal efficiency. The unthrottled engine also yields lower NOx emissions, which were found to be a strong function of fuel-air equivalence ratio. (LCL).

Book excerpt: The objective of this research effort is to obtain the design data-base covering performance, operational characteristics and emissions essential for making a rational decision regarding the selection and design of prototype hydrogen-fueled, air-breathing engines capable of being manufactured for general automotive use. To this end hydrogen-fueled internal combustion engines were divided into fourteen subgroups. An engine representative of each subgroup will be tested during the course of the three year program. The Project Program Plan calls for investigation of pre-intake valve closing fuel ingestion (Pre IVC) hydrogen-fueled engines during the first two years. Work accomplished during the second three months of the project is reported. Activities during the second quarter concentrated on: final apparatus debugging, engine break-in, preliminary testing to determine qualitative apparatus operating characteristics, rearranging of the proposal test schedule and performing of tests with engine 1 (carbureted, throttled, no H2O injection, no EGR and engine 4 (carbureted, unthrottled, no H2O injection, no EGR. The details of these activities are described.

Book excerpt: Progress in a program aimed at obtaining operational and performance data on a prototype pre intake valve closing fuel ingestion (PreIVC) hydrogen-fueled automotive engine is reported. Information is included on the construction and testing of an unthrottled hydrogen delivery system and on flashback during starting. It was determined that the flashback was caused by runaway surface ignition. (LCL).

Book excerpt: Many problems associated with the design and development of hydrogen-air breathing internal combustion engines for automotive applications have been identified by various domestic and foreign researchers. This project addresses the problems identified in the literature, seeks to evaluate potential solutions to these problems, and will obtain and document a design data-base convering the performance, operational and emissions characteristics essential for making rational decisions regarding the selection and design of prototype hydrogen-fueled, airbreathing engines suitable for manufacture for general automotive use. Information is included on the operation, safety, emission, and cost characteristics of hydrogen engines, the selection of a test engine and testing facilities, and experimental results. Baseline data for throttled and unthrottled, carburetted, hydrogen engine configurations with and without exhaust gas recirculation and water injection are presented. In addition to basic data gathering concerning performance and emissions, the test program conducted was formulated to address in detail the two major problems that must be overcome if hydrogen-fueled engines are to become viable: flashback and comparatively high NOx emissions at high loads. In addition, the results of other hydrogen engine investigators were adjusted, using accepted methods, in order to make comparisons with the results of the present study. The comparisons revealed no major conflicts. In fact, with a few exceptions, there was found to be very good agreement between the results of the various studies.

Download or read book Hydrogen as an Energy Carrier written by Carl-Jochen Winter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technologies of hydrogen's energetic utilization have been known for a long time. But aspects of system analysis, energy economics, and ecology that would come into play in introducing it into energy systems nave received much less attention. For those reasons, this book attempts to show the development path of a hydrogen economy, based on assured technological knowledge. One special concern has been to demonstrate, on one hand, how these developments would fit into existing energy supply structures, and, on the other, how they would contribute to further development of the energy system as a whole. With that goal in mind it is necessary to contrast the obvious advantages of hydrogen with the large efforts that would be required for its introduction. This total-systems approach led to a three-part organization of the book that also aids the reader in quickly identifying those parts that are of special interest to him. Section A essentially explains why it is necessary today to think about a new synthetic energy carrier. It also describes the irreplacable and growing role of hydrogen as a chemical raw material, and it explains technologies that al ready exist for its energetic use or that need further development. An attempt has also been made to prove that hydrogen's safety characteristics indeed per mit its handling and use as an energy carrier. Hopefully, all this will show that hydrogen, together with electricity, could be the universally employable energy carrier of a future non-fossil energy supply system.

Download or read book Analysis of Experimental Hydrogen Engine Data and Hydrogen Vehicle Performance and Emissions Simulation written by and published by . This book was released on 1996 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports the engine and vehicle simulation and analysis done at Lawrence Livermore (LLNL) as a part of a joint optimized hydrogen engine development effort. Project participants are: Sandia National Laboratory, California (SNLC), responsible for experimental evaluation; Los Alamos National Laboratory (LANL), responsible for detailed fluid mechanics engine evaluations, and the University of Miami, responsible for engine friction reduction. Fuel cells are considered as the ideal power source for future vehicles, due to their high efficiency and low emissions. However, extensive use of fuel cells in light-duty vehicles is likely to be years away, due to their high manufacturing cost. Hydrogen-fueled, spark-ignited, homogeneous-charge engines offer a near-term alternative to fuel cells. Hydrogen in a spark-ignited engine can be burned at very low equivalence ratios, so that NO(subscript x) emissions can be reduced to less than 10 ppm without catalyst. HC and CO emissions may result from oxidation of engine oil, but by proper design are negligible (a few ppm). Lean operation also results in increased indicated efficiency due to the thermodynamic properties of the gaseous mixture contained in the cylinder. The high effective octane number of hydrogen allows the use of a high compression ratio, further increasing engine efficiency.
