Book excerpt: Internal Combustion Engines (ICE) revolutionized transportation at the dawn of the 20th century. Continuous refinement of the theory and design of ICE has allowed them to become so well optimized to the task of human transport that they are often taken for granted, only thought of on the rare occasion when they fail to work properly. Nobody speaks about the challenge of designing an ICE that is acceptable for the task of moving people from one place to another. Today, in the age of the remotely piloted aircraft (RPA), another opportunity arises to instigate the continuous refinement of the ICE to a novel task. Small ICE have been used to propel small model aircraft for decades, but the recent exponential growth in demand for RP A in military applications has given rise to an expectation from small ICE which far surpasses current capabilities: RPA require the ability to operate at higher altitudes, in more extreme environmental conditions, and with greater fuel efficiency than is currently possible. Small internal combustion engines, particularly those ranging in power from 1 kW to 15 kW, propel many Group 1 and Group 2 remotely piloted aircraft (RPA) platforms that play an increasingly significant role in the Department of Defense. Most engines used for defense applications are commercial off-the-shelf products, designed for hand tools and hobby aircraft. Efficiency of these engines is low and thermal loss is a significant contributor to the energy loss. Existing thermal energy loss models are based on data from much larger engines. Whether these loss models scale to the engine size class of interest, however, has not yet been established. The Small Engine Research Bench (SERB) was used previously to measure spatially and temporally averaged heat flux, as well as local, instantaneous heat flux at several external locations, for a series of small engines. This investigation will obtain time averaged crank-angle-resolved measurements of the in-cylinder gas temperature using Fourier transform infrared (FTIR) absorption thermometry. The results, coupled with heat flux measurements, will enable the validation or refinement of existing thermal energy loss models.- author's summary

Available in PDF, EPUB and Kindle. Book excerpt: Spectrometers, both interferometric and dispersive, are a useful tool for measuring high-resolution spectra in combustion. The method of spectral acquisition depends on the wavelength region of interest, required speed of the measurement and available light sources. A novel method which uses a Fourier-Transform Infrared Spectrometer to measure dynamic processes is presented. This method is used to measure time-resolved emission spectra of H2O, CO2, hydrocarbon fuels, and various aldehyde-like molecules in an internal combustion engine. Gas properties are inferred from the measured spectra. A variation of the method is used to measure time-resolved absorption spectra in a reciprocating engine. The resulting spectra are used to determine gas temperatures and mole fractions of H2O and fuel. Ultraviolet absorption spectra of the hydroxyl radical in various H2/Air and CH4/Air diffusion flames are measured using a Czerny-Turner grating spectrometer. Gas temperatures are inferred from the spectra. Temperature measurements at 31.25 kHz are demonstrated using a high-speed version of the instrument.

Book Synopsis Laser Diagnostics and Optical Measurement Techniques in Internal Combustion Engines by : Hua Zhao
Download or read book Laser Diagnostics and Optical Measurement Techniques in Internal Combustion Engines written by Hua Zhao and published by SAE International. This book was released on 2012-07-30 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing concern about CO2 emissions and energy prices has led to new CO2 emission and fuel economy legislation being introduced in world regions served by the automotive industry. In response, automotive manufacturers and Tier-1 suppliers are developing a new generation of internal combustion (IC) engines with ultra-low emissions and high fuel efficiency. To further this development, a better understanding is needed of the combustion and pollutant formation processes in IC engines. As efficiency and emission abatement processes have reached points of diminishing returns, there is more of a need to make measurements inside the combustion chamber, where the combustion and pollutant formation processes take place. However, there is currently no good overview of how to make these measurements. Based on the author’s previous SAE book, Engine Combustion Instrumentation and Diagnostics, this book focuses on laser-based optical techniques for combustion flows and in-cylinder measurements. Included are new chapters on optical engines and optical equipment, case studies, and an updated description of each technique. The purpose of this book is to provide, in one publication, an introduction to experimental techniques that are best suited for in-cylinder engine combustion measurements. It provides sufficient details for readers to set up and apply these techniques to IC engines and combustion flows.

This book was released on 1986 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A technique termed "coherent, anti-Stokes Raman spectroscopy" (CARS) has been developed at the Combustion and Carbonization Research Laboratory of CANMET's Energy Research Laboratories for the measurement of temperature and species concentration. The advantages of this technique over conventional probing methods are improved temporal and spatial resolution; it is nonintrusive and turbulence parameters can be determined. This report discusses the theoretical basis for such a technique and some of the practical considerations involved in the optical arrangement. To apply this technique successfully, it was necessary to develop sophisticated software and hardware. The incorporation of these and the optics into a CARS system is discussed, together with the theory of its application"--Abstract, p. iii.
