Available in PDF, EPUB and Kindle. Book excerpt: This paper presents research efforts made in three different phases with the objective of improving the fuel economy of and reducing exhaust emissions from conventional, carbureted, two-stroke spark ignition (SI) engines, which are widely employed in two-wheel transportation in India. A review concerning the existing two-stroke engine technology for this application is included. In the first phase, a new scavenging system was developed and tested to reduce the loss of fresh charge through the exhaust port. In die second phase, the following measures were carried out to improve the combustion process: (1) using an in-cylinder catalyst, such as copper, chromium, and nickel, in the form of coating; (2) providing moderate thermal insulation in the combustion chamber, either by depositing thin ceramic material or by metal inserts; (3) developing a high-energy ignition system; and (4) employing high-octane fuel, such as methanol, ethanol, eucalyptus oil, and orange oil, as a blending agent with gasoline. Based on the effectiveness of the above measures, an optimized design was developed in the final phase to achieve improved performance. Test results indicate that with an optimized two-stroke SI engine, the maximum percentage improvement in brake thermal efficiency is about 31%, together with a reduction of 3400 ppm in hydrocarbons (HC) and 3% by volume of carbon monoxide (CO) emissions over the normal engine (at 3 kW, 3000 rpm). Higher cylinder peak pressures (3-5 bar), lower ignition delay (2-4°CA)° and shorter combustion duration (4-10 °CA) are obtained. The knock-limited power output is also enhanced by 12.7% at a high compression ratio (CR) of 9:1. The proposed modifications in the optimized design are simple, low-cost and easy to adopt for both production and existing engines.
Download or read book AN EXPERIMENTAL INVESTIGATION ON THE EFFECT OF DUAL COIL IGNITION DISCHARGES ON DILUTE COMBUSTION IN A SPARK IGNITION ENGINE written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Dilute combustion is an effective way to increase part-load efficiencies in a Spark Ignition (SI) engine. However, dilute combustion leads to a slower combustion rate and longer burn durations, which results in higher heat transfer loss. To overcome this, some degree of charge flow enhancement exists in modern engines that improves combustion rate and shortens burn durations. This flow enhancement has an adverse effect on performance of the modern Transistorized Coil Ignition (TCI) system and hence presents a limitation on improving combustion rates. Additionally, dilute combustion has a detrimental effect on combustion stability, wherein a larger variation in engine cycle work is observed from cycle to cycle which degrades engine performance. Improving combustion stability under dilution poses a challenge for the modern single coil ignition system, which is where the motivation lies in this research. This research details the development and instrumentation of a Configurable Dual Coil Ignition (CDCI) system that is later tested on a single cylinder metal engine. The effectiveness of different ignition profiles developed with the CDCI system in extending the dilution limit while maintaining combustion performance and lower cycle-cycle variations, thereby improving fuel conversion efficiency, is investigated. Effects of dilution by excess air and internal (exhaust) residuals on the performance of these ignition profiles are investigated under different operating conditions. In-cylinder flow is enhanced by means of tumble planks installed in the intake port of the engine. The impact of enhanced in-cylinder flow on the capabilities of the developed ignition profiles is also investigated under different conditions. Moreover, effects of different spark plug gap sizes and orientations are also investigated. Although majority of the tests are done with Direct Injection (DI) gasoline, some tests are performed with Port Fuel Injection (PFI) methane to compare the effects of fuel delivery and charge preparation.

Download or read book Automotive Fuels Reference Book written by Paul Richards and published by SAE International. This book was released on 2014-03-05 with total page 870 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first two editions of this title, published by SAE International in 1990 and 1995, have been best-selling definitive references for those needing technical information about automotive fuels. This long-awaited new edition has been thoroughly revised and updated, yet retains the original fundamental fuels information that readers find so useful. This book is written for those with an interest in or a need to understand automotive fuels. Because automotive fuels can no longer be developed in isolation from the engines that will convert the fuel into the power necessary to drive our automobiles, knowledge of automotive fuels will also be essential to those working with automotive engines. Small quantities of fuel additives increasingly play an important role in bridging the gap that often exists between fuel that can easily be produced and fuel that is needed by the ever-more sophisticated automotive engine. This book pulls together in a single, extensively referenced volume, the three different but related topics of automotive fuels, fuel additives, and engines, and shows how all three areas work together. It includes a brief history of automotive fuels development, followed by chapters on automotive fuels manufacture from crude oil and other fossil sources. One chapter is dedicated to the manufacture of automotive fuels and fuel blending components from renewable sources. The safe handling, transport, and storage of fuels, from all sources, are covered. New combustion systems to achieve reduced emissions and increased efficiency are discussed, and the way in which the fuels’ physical and chemical characteristics affect these combustion processes and the emissions produced are included. There is also discussion on engine fuel system development and how these different systems affect the corresponding fuel requirements. Because the book is for a global market, fuel system technologies that only exist in the legacy fleet in some markets are included. The way in which fuel requirements are developed and specified is discussed. This covers test methods from simple laboratory bench tests, through engine testing, and long-term test procedures.
