Available in PDF, EPUB and Kindle. Book excerpt: The homogeneous charge, compression-ignition (HCCI) combustion process has the potential to significantly reduce NOx and particulate emissions, while achieving high thermal efficiency and the capability of operating with a wide variety of fuels. This makes the HCCI engine an attractive technology that can ostensibly provide diesel-like fuel efficiency and very low emissions, which may allow emissions compliance to occur without relying on lean aftertreatment systems. A profound increase in the level of research and development of this technology has occurred in the last decade. This book gathers contributions from experts in both industry and academia, providing a basic introduction to the state-of-the-art of HCCI technology, a critical review of current HCCI research and development efforts, and perspective for the future. Chapters cover: Gasoline-Fueled HCCI Engines; Diesel-Fueled HCCI Engines; Alternative Fuels and Fuel Additives for HCCI Engines; HCCI Control and Operating Range Extension; Kinetics of HCCI Combustion; HCCI Engine Modeling Approaches.In addition to the extensive overview of terminology, physical processes, and future needs, each chapter also features select SAE papers (a total of 41 are included in the book), as well as a comprehensive list of references related to the subjects. Homogeneous Charge Compression Ignition (HCCI) Engines: Key Research and Development Issues provides a valuable base of information for those interested in learning about this rapidly-progressing technology which has the potential to enhance fuel economy and reduce emissions.

Available in PDF, EPUB and Kindle. Book excerpt: Homogeneous charge compression ignition (HCCI)/controlled auto-ignition (CAI) has emerged as one of the most promising engine technologies with the potential to combine fuel efficiency and improved emissions performance, offering reduced nitrous oxides and particulate matter alongside efficiency comparable with modern diesel engines. Despite the considerable advantages, its operational range is rather limited and controlling the combustion (timing of ignition and rate of energy release) is still an area of on-going research. Commercial applications are, however, close to reality. HCCI a.

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.
Download or read book SI to HCCI Operation of a Small Macro scale 4 stroke Engine written by Peter Lynn Therkelsen and published by . This book was released on 2009 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homogeneous Charge Compression Ignition (HCCI) combustion is different from conventional Spark Ignition (SI) combustion in a gasoline engine and Compression Ignition (CI) diffusion combustion in a diesel engine. The combination of a diluted and premixed fuel and air mixture with multiple ignition sites throughout the combustion chamber eliminates the high combustion temperature zones and prevents the production of soot particles, hence ultra-low NOx and particulate emissions. HCCI engines are characterized by higher efficiency than traditional SI and CI engines. Excluding the MEMS scale, HCCI research has focused on engine sizes used in modern passenger vehicles or lightweight trucks. Engines studied range in displacement volumes from 0.447 to 14.5 L. Use of HCCI combustion in smaller personal transportation sized engines has only been theorized. The effects of scale on SI and CI engine performance has been well documented and are typified with changes to operational ranges and efficiency. The focus of this research is to determine the effects of engine size reduction on HCCI combustion in a four-stroke engine. The operability of a small scale HCCI engine was first examined using a traditional large scale HCCI engine computer model. The model both indicated that small scale HCCI operation is achievable and outlined experimental requirements to achieve successful engine operation. A 25 cc SI engine was modified and used to explore the operability of HCCI in a small scale engine. Initial experimental tests attempting to start the small engine in HCCI mode with engine inlet heating were not successful. These tests, based upon modeling results, did not produce an operable small scale HCCI engine. Studies of the heat transfer characteristics of a small engine with high surface area to volume ratio were performed. These studies indicated that all engine inlet heating was lost from the engine before the energy could be employed in initiating auto-ignition of the fuel and air. Preheating of the engine by operating in SI mode then transitioning to HCCI operation resulted in sustainable small scale HCCI. Small macro-scale HCCI operability was characterized with respect to operational parameters. Performance characteristics were compared within the HCCI operational window and to the SI engine. The performance of the small macro-scale HCCI engine is far worse than that of large macro-scale HCCI engines. Future work focusing on proper thermal management as well as SI to HCCI transitioning is recommended.

This book was released on 2018 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the search for cleaner and greener power generation systems, researchers are relentlessly searching for a new engine technology that can perform at a higher efficiency with lower environmentally unsafe gases and particulate matter emissions. A Homogeneous Charge Compression Ignition (HCCI) is one such class of engines, which use high compression ratio to ignite pre-mixed homogeneous air-fuel mixture without the need for any spark plugs. HCCI engines have been drawing attention due to its 1) high operating efficiency and 2) low nitrogen oxide (NOX) and particulate matters (PM) emissions because of lower combustion temperatures. One of the major challenges associated with the HCCI engine is the very rapid combustion rate that results in very high rate of pressure rise and high rate of heat release. One way to address this issue is to reduce the combustion temperature by inducting exhaust gas recirculation (EGR) inside the combustion chamber to dilute the reactant mixture and subsequently lower the reaction rate, operating temperature, and harmful emissions. EGR gases are used to increase the heat capacity of the burned gases for a given quantity of heat release, which in turn lowers the combustion temperature. Particularly, in a four-stroke HCCI engine, hot EGR gases enhance combustion process, mainly due to the high temperature of the intake mixture. In study, a comprehensive simulation analysis of the HCCI engine is carried out using a CFD model that includes solution of three-dimensional RANS equations and turbulent closure model along with the detailed chemical kinetics and non-isothermal wall heat loss to show a quantitative evaluation of the sensitivity of the EGR rate on the heat-release rates (HRR), engine efficiency, and emission.
