Book Description
This book covers the various advanced reciprocating combustion engine technologies that utilize natural gas and alternative fuels for transportation and power generation applications. It is divided into three major sections consisting of both fundamental and applied technologies to identify (but not limited to) clean, high-efficiency opportunities with natural gas fueling that have been developed through experimental protocols, numerical and high-performance computational simulations, and zero-dimensional, multizone combustion simulations. Particular emphasis is placed on statutes to monitor fine particulate emissions from tailpipe of engines operating on natural gas and alternative fuels.
Assessment of Fuel Economy Technologies for Light-Duty Vehicles

Book Description
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 Description
Concern about the reduced availability and the increased cost of petroleum fuels prompted great efforts in recent years to reduce the fuel consumption of auto mobiles. The ongoing efforts to reduce fuel consumption have addressed many relevant factors, including increased engine performance, reduced friction, use of lightweight materials, and reduced aerodynamic drag. The results of the investigations assessing the various factors affecting fuel economy have been published in journals, conference proceedings, and in company and government reports. This proliferation of technical information makes it difficult for workers to keep abreast of aU developments. The material presented in this book brings together in a single volume much of the relevant materials, summarizes many of the state-of-the-art theories and data, and provides extensive lists of references. Thus, it is hoped that this book will be a useful reference for specialists and practicing engineers interested in the fuel economy of automobiles. J. C. HILLIARD o. S. SPRINGER vii CONTENTS 1.

Book Description
The main goal of this study was to obtain a detailed comparison of engine performance and exhaust emissions from a spark-ignitionengine fuelled by natural gas and by gasoline. The test facility consists of a Ricardo Hydra, four-stroke single-cylinder spark-ignitiion research engine, 450 cc swept volume. The results presented in this study were obtained over a wide range of engine speeds, loads and air-fuel ations under steady-state operating conditions. The data were acquired with use of the standard Ricardo bathtub combustion chamber and flat piston for both fuels at the compression ration of 8.25:1. The engine speeds selected for testing were 1000, 2000 and 3000 rpm. The relative air-fuel rations ranged from 1.00 at 0.10 increment to the lean limit of combustion. Each fuel was tested at wide-open throttle (WOT), and part-load (65% full-load and 35% full load) conditions, and at MBT (Minimum Spark Advance for Best torque) timing. The general conclusion is that the emission levels are lower (5 to 50%) for natural gas than those for gasoline. The performance parameters, such as efficiency and specific fuel consumption, also favour natural gas, particularly at lean air-fuel rations. A further improvement in natural gas engine performance and emissions is possible through faster burn combustion chambers development, higher compression ratios and multiple-spark ignition systems application.
