Book excerpt: Engine Testing: Theory and Practice brings together the information on both the theory and practice of engine testing that engineers in this field must have available. Organized into 19 chapters, this book begins with a description of the engine test cell, including the salient features of its main types. Subsequent chapters deal with the other main components of an engine testing installation: the control room and the ventilation systems. Other chapters discuss the essential features of a test installation fuel supply system, as well as the characteristics, advantages, and disadvantages of the various types of dynamometer. The measurements of torque, power, speed, fuel consumption, air consumption, heat loss, and mechanical loss are also explained. Other topics of significance include the process of combustion, exhaust emissions, data logging, and statistical analysis. This material will be very useful to practicing test engineers and students.

Download or read book Vortex Controlled Multifuel Combustion written by D. A. Willis and published by . This book was released on 1963 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was undertaken to determine the effect vortex-type flow has on the multifuel operation of a 3.5in. bore x 4.5in. stroke, two-stroke cycle, loop scavenged, air cooled high-speed compression-ignition engine. The open-type, Lanz-type and Ricardo-type chambers were investigated but the most effective results were obtained with a vortex combustion chamber concentric to the cylinder axis and separated from the cylinder by a plate having swirl producing passages around its periphery and a protruding central throat which the piston engaged near TDC. This chamber operated smoothly, effeciently and at high specific output on a number of fuels at a compression ratio of 25:1 without the necessity of intake air throttling at light load. High-speed photographs were taken of the combustion process within this chamber after it had been modified and fitted with a quartz window. The combustion photographs along with the engine test results provided a means by which the flow pattern and combustion process could be analyzed. (Author).

Download or read book Study of Ignition and Emissions in a Direct Injected, Compression Ignition Natural Gas Engine written by Ivan Gogolev and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas direct injection and glow plug ignition assist technologies were implemented in a single-cylinder, optically-accessible engine. Initial experiments studied the effects of injector and glow plug shield geometry on ignition quality. Injector and shield geometric effects were found to be significant, with only two of 20 tested geometric combinations resulting in reproducible combustion. Further experiments explored the effects of equivalence ratio and intake pressure on ignition delay, engine performance, and exhaust emissions. Combustion was found to proceed in a stratified-premixed mode at lower equivalence ratios, and a free-mixing mode at the higher equivalence ratios. Both combustion modes resulted in high NOx emissions. Stratified-premixed combustion produced higher hydrocarbon emissions, and lower levels of particulate matter and carbon monoxide, when compared to free-mixing combustion. Higher intake pressure was found to reduce all emissions levels. This effect was largely attributed to better charge mixing achieved from pressure-driven increase in engine swirl momentum.

Download or read book Characterization of Injection Pressure Effects on Gasoline Compression Ignition Combustion written by Cory Andrew Adams and published by . This book was released on 2017 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Varying the fuel stratification during gasoline compression ignition (GCI) combustion has been shown to impact important combustion parameters and emissions. The effect of varied injection pressure and injection timing on the fuel stratification and formation of nitric oxide (NOx) emissions was studied at two engine operating conditions. At a 1500 revolutions per minute (rpm) engine condition, a 100 bar increase in injection pressure required a 1.4o crankangle retard of the injection timing to maintain constant NOx emissions. The required injection timing shift to maintain constant NOx emissions at a 1900 rpm condition for a 100 bar increase in injection pressure was 2.5o crankangle. A skip-firing injection strategy illustrated the importance of the second injection in creating fuel stratification and promoting ignition for GCI combustion. The effects of injected fuel mass variability on combustion stability were investigated using a randomized injection strategy. Analysis showed that the injected fuel mass uncertainty required to induce combustion instability was between 3.2-4.8%. Three-dimensional computational fluid dynamics (CFD) and a one-dimensional (1-D) turbulent jet model were used to analyze the fuel-air mixing. A quasi-steady jet timescale was used to non-dimesionalize the time after start of injection. The ability of the timescale to collapse the jet vapor penetration and fuel-mass-weighted PDF of mixture fraction/equivalence ratio were evaluated for a variety of conditions at times significantly after end of injection. The quasi-steady jet timescale reasonably collapsed jet vapor penetration for various injection pressures but did not collapse the fuel-mass-weighted PDFs of equivalence ratio at times of interest during transient changes to the ambient gas density unless changes in spray spreading angle are accounted for. The 1-D jet model was benchmarked to CFD and evaluated at different conditions to analyze the assumptions of the 1-D model. A sensitivity analysis of the 1-D model was conducted. The 3-D CFD results are utilized to analyze the connection between the fuel-air distribution and the engine-out NOx emissions at the constant-NOx engine operating conditions. Computational fluid dynamics results showed similar equivalence ratio distributions resulted in relatively constant NOx emissions.
