Available in PDF, EPUB and Kindle. Book excerpt: A homogeneous charge compression ignition engine operates by injecting liquid fuel directly in a combustion chamber, and mixing the fuel with recirculated exhaust and fresh air through an auto ignition condition of the fuel. The engine includes at least one turbocharger for extracting energy from the engine exhaust and using that energy to boost intake pressure of recirculated exhaust gas and fresh air. Elevated proportions of exhaust gas recirculated to the engine are attained by throttling the fresh air inlet supply. These elevated exhaust gas recirculation rates allow the HCCI engine to be operated at higher speeds and loads rendering the HCCI engine a more viable alternative to a conventional diesel engine.

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.

This book was released on 2015-09-28 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: The light-duty vehicle fleet is expected to undergo substantial technological changes over the next several decades. New powertrain designs, alternative fuels, advanced materials and significant changes to the vehicle body are being driven by increasingly stringent fuel economy and greenhouse gas emission standards. By the end of the next decade, cars and light-duty trucks will be more fuel efficient, weigh less, emit less air pollutants, have more safety features, and will be more expensive to purchase relative to current vehicles. Though the gasoline-powered spark ignition engine will continue to be the dominant powertrain configuration even through 2030, such vehicles will be equipped with advanced technologies, materials, electronics and controls, and aerodynamics. And by 2030, the deployment of alternative methods to propel and fuel vehicles and alternative modes of transportation, including autonomous vehicles, will be well underway. What are these new technologies - how will they work, and will some technologies be more effective than others? Written to inform The United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) Corporate Average Fuel Economy (CAFE) and greenhouse gas (GHG) emission standards, this new report from the National Research Council is a technical evaluation of costs, benefits, and implementation issues of fuel reduction technologies for next-generation light-duty vehicles. Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles estimates the cost, potential efficiency improvements, and barriers to commercial deployment of technologies that might be employed from 2020 to 2030. This report describes these promising technologies and makes recommendations for their inclusion on the list of technologies applicable for the 2017-2025 CAFE standards.

Book Synopsis Assessment of Fuel Economy Technologies for Light-Duty Vehicles by : National Research Council
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.
Book Synopsis Dynamic Control of a Homogeneous Charge Compression Ignition Engine by :
Download or read book Dynamic Control of a Homogeneous Charge Compression Ignition Engine written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A homogenous charge compression ignition engine is operated by compressing a charge mixture of air, exhaust and fuel in a combustion chamber to an autoignition condition of the fuel. The engine may facilitate a transition from a first combination of speed and load to a second combination of speed and load by changing the charge mixture and compression ratio. This may be accomplished in a consecutive engine cycle by adjusting both a fuel injector control signal and a variable valve control signal away from a nominal variable valve control signal. Thereafter in one or more subsequent engine cycles, more sluggish adjustments are made to at least one of a geometric compression ratio control signal and an exhaust gas recirculation control signal to allow the variable valve control signal to be readjusted back toward its nominal variable valve control signal setting. By readjusting the variable valve control signal back toward its nominal setting, the engine will be ready for another transition to a new combination of engine speed and load.
