Book excerpt: UNDESIRABLE EMISSIONS IN INTERNAL COMBUStion engines are of major concern beause of their negative impact on air quality, human health, and global warming. Therefore, there is a concerted effort by most governments to control them. Undesirable emissions include unburned hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM). In this chapter, we present the U.S. and European emissions standards, both for gasoline and diesel operated engines, and strategies to control the undesirable emissions. The role of engine design, vehicle operating variables, fuel quality, and emission control devices in minimizing the above-listed pollutants are also detailed in this chapter. Emissions is a collective term that is used to describe the undesired gases and particles which are released into the air or emitted by various sources, Its amount and the type change with a change in the industrial activity, technology, and a number of other factors, such as air pollution regulations and emissions controls [535]. The U.S. Environmental Protection Agency (EPA) is primarily concerned with emissions that are or can be harmful to the public at large. EPA considers carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), paniculate matter (PM), and sulfur dioxide (SO2) as the pollutants of primary concern, called the Criteria Pollutants. These pollutants originate from the following four types of sources. 1. Point sources, which include facilities such as factories and electric power plants. 2. Mobile sources, which include cars and trucks but also lawn mowers, airplanes, and anything else that moves and releases pollutants into the air. 3. Biogenic sources, which include trees and vegetation, gas seeps, and microbial activity. 4. Area sources, which consist of smaller stationary sources such as dry cleaners and degreaslng operations.

Available in PDF, EPUB and Kindle. Book excerpt: Internal combustion engines are among the most fascinating and ingenious machines which, with their invention and continuous development, have positively influenced the industrial and social history during the last century, especially by virtue of the role played as propulsion technology par excellence used in on-road private and commercial transportation. Nowadays, the growing attention towards the de-carbonization opens up new scenarios, but IC engines will continue to have a primary role in multiple sectors: automotive, marine, offroad machinery, mining, oil & gas and rail, power generation, possibly with an increasing use of non-fossil fuels. The book is organized in monothematic chapters, starting with a presentation of the general and functional characteristics of IC engines, and then dwelling on the details of the fluid exchange processes and the definition of the layout of intake and exhaust systems, obviously including the supercharging mechanisms, and continue with the description of the injection and combustion processes, to conclude with the explanation of the formation, control and reduction of pollutant emissions and radiated noise.

Download or read book Advanced Combustion Science written by Tsuneo Someya and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-uniform combustion, as encountered in diesel and gas turbine engines, furnaces, and boilers, is responsible for the conversion of fossil fuel to energy and also for the corresponding formation of pollutants. In spite of great research efforts in the past, the mechanism of non-uniform combustion has remained less explored than that of other combustion types, since it consists of many, mostly transient processes which influence each other. In view of this background, a group research project, "Exploration of Combustion Mechanism", was established to explore the mechanism of combustion, especially that of diffusive combustion, and also to find efficient ways to control the combustion process for better utilization of fuel and the reduction of pollutant emission. The group research was started, after preparatory activity of 2 years, in April 1988, for a period of 3 years, as a project with a Grant-in-Aid for Scientific Research of Priority Area subsidized by the Ministry of Education, Science and Culture of Japan. The entire group of 43 members was set up as an organizing committee of 13 members, and five research groups, consisting of 36 members. The research groups were: (1) Steady combustion, (2) Unsteady spray combustion, (3) Control of combustion, (4) Chemistry of combustion, and (5) Effects of fuels. At the beginning of the project it was agreed that we should pursue the mechanism of combustion from a scientific viewpoint, namely, the target of the project was to obtain the fundamentals, or "know why", rather than "know how" of combustion.

Download or read book Hazardous Air Emissions from Incineration written by Calvin R. Brunner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a comprehensive handbook on the relationship of air pollution to incineration. Incineration is becoming the predominant method of dealing with many of our waste products and its most significant envi ronmental impact is on the air. This book includes information on emissions as well as on equipment design. Two chapters deal with the regulations governing incinerator emissions as well as the thermal destruction of hazardous wastes. Four chapters describe the nature of the emissions generated by the incin eration process. These particulate, gaseous, and odor emissions, are hazardous as well as deleterious to public well-being and aesthetics. Also included is a complete and timely discussion of dioxin generation and discharges. Three chapters describe the incineration equipment in general use today and methods of calculating gas flows and air discharges from these systems. Five chapters discuss the types of gas cleaning equipment available with sizing information and expected efficiencies. The nature of the gas cleaning process is discussed in detail. Criteria for selection of the opti mum system for a particular application is also included. The dispersion of an atmospheric discharge to the surrounding areas and/or communities is a vital concern in assessing the nature of that discharge and its impact, or potential hazards. A chapter is devoted to a relative simple method of estimating atmospheric dispersion.

Download or read book Computational Optimization of Internal Combustion Engines written by Yu Shi and published by Springer Science & Business Media. This book was released on 2011-06-22 with total page 323 pages. 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.
