This book was released on 2014 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of modern Diesel engines in automotive industry has been widely recognized for reasons of their distinguished performances on fuel economy, durability, and reliability. Meanwhile, NOx and particulate matters (PM) emissions have been the main concerns in the evolution of Diesel engines as more and more stringent emission standards have been legislated against Diesel engine emissions worldwide. In addition, as the Greenhouse gas emissions are receiving more and more concerns due to global warming issues, the demand of fuel economy improvement is increasing significantly. The objective of this research is to develop systematic control methodologies, based on fundamental insight into the system characteristics, to improve the overall fuel economy and emission performance of integrated Diesel engine and aftertreatment systems. The test platform of this research is a medium-duty Diesel engine equipped with high-pressure common-rail fuel injection system, dual-loop exhaust gas recirculation systems, variable geometry turbocharger system, and an integrated aftertreatment system including a Diesel oxidation catalyst (DOC), Diesel particulate filter (DPF), and two-catalyst selective catalytic reduction (SCR) system. The topics of this research fall into two groups. The first group focuses on the modeling, estimation, and control of integrated aftertreatment systems based on the interactions between the subsystems with the objective of maintaining low tailpipe emissions at low cost. Topics covered in this group include the modeling and observer-based estimations for oxygen concentration and thermal behaviors across the DOC and DPF, state estimator design for SCR system using production NOx sensor measurements, and the active NO/NO2 ratio controller design for DOC and DPF to improve the SCR performance. The second group mainly concentrates on the modeling, estimation, and control of integrated engine-aftertreatment systems grounded on the interactions between engine and aftertreatment systems to simultaneously maintain high fuel efficiency and low tailpipe emissions. Topics contained in this group include the air-fraction modeling and estimation for Diesel engines coupled with aftertreatment systems during normal operations and active DPF regenerations, control-oriented thermal model for integrated Diesel engine and aftertreatment system active thermal management, and integrated Diesel engine and aftertreatment active NOx emissions control for fuel economy improvement. The control-oriented models, observers, and controllers of integrated Diesel engine and aftertreatment systems proposed in this research, when applied in automotive fields, have potentials of improving the engine fuel efficiency, reliability, and reducing tailpipe emissions in systematic, real-time, and cost-effective manners.

This book was released on 2005 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: "There is a growing demand for energy usage in the world, primarily due to increasing economic activity. This need can be met by pursuing increased power generation. However the impact of emissions from power generation sources on the health of human beings and environmental continues to be a major concern. In order to maintain and enhance environmental quality there is a need for the development of clean energy products. A diesel aftertreatment device was developed at RIT to reduce particulate matter (PM) in the emissions of generators and diesel engines by using the combination of non-thermal plasma oxidation and emission catalyst technologies. The non-thermal plasma (corona discharge) created by a high voltage electrode produces ionized gas or plasma in the charging section of the device. Simultaneously gas atoms are excited, producing highly reactive O, OH, and NO2 radicals. These radicals oxidize PM to gaseous products including CO, and CO2. The device has a low pressure drop compared with other diesel aftertreatment devices since it self-regenerates and there is no accumulation of PM in the system. The scope of this thesis is to develop a numerical model to simulate the performance of this diesel aftertreatment device. The model calculates the diesel exhaust conditions, plasma generation condition, electric field, power consumption, particulate collection, and particle removal. The model results agree with the experimental data, which proves that the model can be used for system performance prediction. Based on keeping the same PM removal efficiency and back pressure effects on diesel engine, a method was developed for system scale-up or scale-down"--Abstract.

Download or read book ADVANCED DIESEL ENGINE AND AFTERTREATMENT TECHNOLOGY DEVELOPMENT FOR TIER 2 EMISSIONS written by and published by . This book was released on 2003 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced diesel engine and aftertreatment technologies have been developed for multiple engine and vehicle platforms. Tier 2 (2007 and beyond) emissions levels have been demonstrated for a light truck vehicle over a FTP-75 test cycle on a vehicle chassis dynamometer. These low emissions levels are obtained while retaining the fuel economy advantage characteristic of diesel engines. The performance and emissions results were achieved by integrating advanced combustion strategies (CLEAN Combustion{copyright}) with prototype aftertreatment systems. CLEAN Combustion{copyright} allows partial control of exhaust species for aftertreatment integration in addition to simultaneous NOx and PM reduction. Analytical tools enabled the engine and aftertreatment sub-systems development and system integration. The experimental technology development methodology utilized a range of facilities to streamline development of the eventual solution including utilization of steady state and transient dynamometer test-beds to simulate chassis dynamometer test cycles.

Book excerpt: The objective of this book is to present a fundamental development of the science and engineering underlying the design of exhaust aftertreatment systems for automotive internal combustion engines. No pre-requisite knowledge of the field is required: our objective is to acquaint the reader, whom we expect to be new to the field of emissions control, with the underlying principles, control methods, common problems, and fuel effects on catalytic exhaust aftertreatment devices. We do this in hope that they can better understand the previous and current generations of emissions control, and improve upon them. This book is designed for the engineer, researcher, designer, student, or any combination of those, who is concerned with the control of automotive exhaust emissions. It includes discussion of theory and fundamentals applicable to hardware development.

Available in PDF, EPUB and Kindle. Book excerpt: Due to their excellent fuel efficiency, reliability, and durability, compression ignition direct injection (CIDI) engines have been used extensively to power almost all highway trucks, urban buses, off-road vehicles, marine carriers, and industrial equipment. CIDI engines burn 35 to 50% less fuel than gasoline engines of comparable size, and they emit far less greenhouse gases (Carbon Dioxides), which have been implicated in global warming. Although the emissions of CIDI engines have been reduced significantly over the last decade, there remains concern with the Nitrogen Oxides (NOX) and Particulate Matter (PM) emission levels. In 2000, the US EPA proposed very stringent emissions standards to be introduced in 2007 along with low sulfur (

This book was released on 2008-10-19 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 21st Century Truck Partnership (21CTP), a cooperative research and development partnership formed by four federal agencies with 15 industrial partners, was launched in the year 2000 with high hopes that it would dramatically advance the technologies used in trucks and buses, yielding a cleaner, safer, more efficient generation of vehicles. Review of the 21st Century Truck Partnership critically examines and comments on the overall adequacy and balance of the 21CTP. The book reviews how well the program has accomplished its goals, evaluates progress in the program, and makes recommendations to improve the likelihood of the Partnership meeting its goals. Key recommendations of the book include that the 21CTP should be continued, but the future program should be revised and better balanced. A clearer goal setting strategy should be developed, and the goals should be clearly stated in measurable engineering terms and reviewed periodically so as to be based on the available funds.
