This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was to investigate (invisible) preflame reactions taking place in a direct-injection compression ignition (DI-CI) engine during the ignition delay period and their effects on subsequent (visible) combustion reactions. The investigation was focused on the subject for an engine equipped with a high-pressure injection (HPI) unit in order to support the development of high-power-output Diesel engines. The use of HPZ was found to facilitate more air utilization in a DI-CI engine even operated with intake air at unusually high temperatures (e.g., encountered in uncooled engines). In order to achieve these goals, several new research methods were developed-advanced for the study, including Rutgers or Super Imaging System (SIS), spectrometric methods, and Rutgers Animation Program. The tools were employed on an optical single-cylinder Cummins 903 engine. Among the significant results in system development is that the basic methods for high-speed imaging achievable at consecutive cycles, which shed some new insight into complex in-cylinder phenomena. The new research methods developed under the present ARO study permits observation of timed global pictures of preflame propagation under various engine-fuel conditions. New findings of the study include that the fuel injected into the cylinder immediately commences to chemically react, unlike the previous thought that there is a physical delay proceeding actual chemical reactions. The reactions involved during the preflame reactions appear to be low-temperature kinetics controlled processes to affect the onset of visible-ray flame formation and combustion reactions. The preflame reaction species were found rapidly consumed as soon as the heat-releasing flame propagation took place.

Download or read book Burning a Wide Range of Fuels in Diesel Engines written by and published by . This book was released on 1967 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multifuel capabilities in diesel engines can reduce fuel costs while taking advantage of accessible fuel supplies. Of course, there are problems which accompany the use of different fuels in an engine brought about by the variations in the fuel characteristics, (e.g., viscosity, compressibility) and combustion, (e.g., fuel sprays, ignition delay). This collection of papers features 4 papers on combustion theory and 13 papers on solutions to multifuel engine problems. It is augmented by a summary paper by distinguished authors in the field and a bibliography of related papers not included in PT- 11.

Download or read book Researches on Preliminary Chemical Reactions in Spark Ignition Engines written by E. Muehlner and published by BiblioGov. This book was released on 2013-07 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical reactions can demonstrably occur in a fuel-air mixture compressed in the working cylinder of an Otto-cycle (spark ignition) internal-combustion engine even before the charge is ignited by the flame proceeding from the sparking plug. These are the so-called "prelinminary reactions" ("pre-flame" combustion or oxidation), and an exact knowledge of their characteristic development is of great importance for a correct appreciation of the phenomena of engine-knock (detonation), and consequently for its avoidance. Such reactions can be studied either in a working engine cylinder or in a combustion bomb. The first method necessitates a complicated experimental technique, while the second has the disadvantage of enabling only a single reaction to be studied at one time. Consequently, a new series of experiments was inaugurated, conducted in a motored (externally-driven) experimental engine of mixture-compression type, without ignition, the resulting preliminary reactions being detectable and measurable thermometrically.

Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (postgraduate) from the year 2019 in the subject Engineering - Chemical Engineering, , course: M.TECH, language: English, abstract: This work is an experimental study for the measurement of ignition delay characteristics of burning fuel sprays in cylindrical combustion chambers. It is carried out on hot air and high pressure. The objective of the study is to investigation the effect of hot air temperature and a well as high pressure on ignition delay of diesel fuel sprays. The effect of blending of n-Pentane with pure diesel was investigated. An experimental set up was design for this purpose with the emphasis on optical method for measurement of ignition delay at various pressures. The results presented here show that ignition delay of diesel fuel spray decreases with increase in the temperature and pressure of hot air. Results also show the effect of methyl group being more dominant at low ignition temperatures and that of alkyl group being more dominant at higher temperature. Blending of n-pentane with diesel fuel, increase its ignition delay at low ignition temperatures. However, as the concentration of blending fuel was increased beyond 30%, the ignition temperature increase. Ignition temperature for 40% pentane blends is much higher that the pure diesel.

This book was released on 1989 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: The editors explain that the classical formulae and techniques for predicting heat flow do not apply to the unique conditions found in reciprocating engines. They warn the reader--presumed to be aspiring designers of more efficient and less polluting engines--that although these papers, from every country where engineering is practiced, contain nearly all the available knowledge on the subject, no definitive answers emerge, no breakthroughs loom around the next equation. The topics include the transfer of engine heat and of external heat, numerical flow simulation, applications and devices, ignition and quenching, and measurement techniques.

Download or read book Introduction to Modeling and Control of Internal Combustion Engine Systems written by Lino Guzzella and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internal combustion engines still have a potential for substantial improvements, particularly with regard to fuel efficiency and environmental compatibility. These goals can be achieved with help of control systems. Modeling and Control of Internal Combustion Engines (ICE) addresses these issues by offering an introduction to cost-effective model-based control system design for ICE. The primary emphasis is put on the ICE and its auxiliary devices. Mathematical models for these processes are developed in the text and selected feedforward and feedback control problems are discussed. The appendix contains a summary of the most important controller analysis and design methods, and a case study that analyzes a simplified idle-speed control problem. The book is written for students interested in the design of classical and novel ICE control systems.
