Download or read book The Study of Spray Characteristics by Using Video Image Processing written by Mohammad Ismail and published by . This book was released on 2013 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with video image processing analysis study of gasoline ethanol blends as the fuel. The objective of this study is to study about spray characteristics. Investigation of these spray from three type of fuel mixture such as pure gasoline (E0), gasohol (E50) and pure ethanol (E100) at different pressure. The pressures used in this study are 10 MPa and 20 MPa. Spray characteristics focus only on spray penetration and spray cone angle. The video from previous experiment is using to compare. From the video, image is captured frame by frame from start time until finished injection. Time taken for the spray is from 0.03 s to 0.12 s. Video imaging has been analyzed and the result is compared according spray evolution. At the 10 MPa, for E0, produced spray penetration is 120.3 mm at 0.06 s and cone angle 2.89° as the accurate result because at that time are shows the overall spray image. E50, produced the penetration 142.2 mm and cone angle 8.31°. E100, produced over than 120.2 mm penetration while the cone angle is 3.99 °. At the high pressure, result shows for E0 is 131.5 mm penetration and 3.71° of cone angle. E50 shows the penetration length 149 mm and cone angle is 10.87° and for E100 show the penetration and cone angle are over 150 mm and 5.75°. Comparing these result indicate higher pressure better penetration and reduce the cone angle because the density of fuel are used is different. It can conclude the physical properties are related with the spray pattern.
Download or read book Knocking in Gasoline Engines written by Michael Günther and published by Springer. This book was released on 2017-11-21 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book includes the papers presented at the conference discussing approaches to prevent or reliably control knocking and other irregular combustion events. The majority of today’s highly efficient gasoline engines utilize downsizing. High mean pressures produce increased knocking, which frequently results in a reduction in the compression ratio at high specific powers. Beyond this, the phenomenon of pre-ignition has been linked to the rise in specific power in gasoline engines for many years. Charge-diluted concepts with high compression cause extreme knocking, potentially leading to catastrophic failure. The introduction of RDE legislation this year will further grow the requirements for combustion process development, as residual gas scavenging and enrichment to improve the knock limit will be legally restricted despite no relaxation of the need to reach the main center of heat release as early as possible. New solutions in thermodynamics and control engineering are urgently needed to further increase the efficiency of gasoline engines.

Download or read book Automotive Spark Ignited Direct Injection Gasoline Engines written by F. Zhao and published by Elsevier. This book was released on 2000-02-08 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process of fuel injection, spray atomization and vaporization, charge cooling, mixture preparation and the control of in-cylinder air motion are all being actively researched and this work is reviewed in detail and analyzed. The new technologies such as high-pressure, common-rail, gasoline injection systems and swirl-atomizing gasoline fuel injections are discussed in detail, as these technologies, along with computer control capabilities, have enabled the current new examination of an old objective; the direct-injection, stratified-charge (DISC), gasoline engine. The prior work on DISC engines that is relevant to current GDI engine development is also reviewed and discussed. The fuel economy and emission data for actual engine configurations have been obtained and assembled for all of the available GDI literature, and are reviewed and discussed in detail. The types of GDI engines are arranged in four classifications of decreasing complexity, and the advantages and disadvantages of each class are noted and explained. Emphasis is placed upon consensus trends and conclusions that are evident when taken as a whole; thus the GDI researcher is informed regarding the degree to which engine volumetric efficiency and compression ratio can be increased under optimized conditions, and as to the extent to which unburned hydrocarbon (UBHC), NOx and particulate emissions can be minimized for specific combustion strategies. The critical area of GDI fuel injector deposits and the associated effect on spray geometry and engine performance degradation are reviewed, and important system guidelines for minimizing deposition rates and deposit effects are presented. The capabilities and limitations of emission control techniques and after treatment hardware are reviewed in depth, and a compilation and discussion of areas of consensus on attaining European, Japanese and North American emission standards presented. All known research, prototype and production GDI engines worldwide are reviewed as to performance, emissions and fuel economy advantages, and for areas requiring further development. The engine schematics, control diagrams and specifications are compiled, and the emission control strategies are illustrated and discussed. The influence of lean-NOx catalysts on the development of late-injection, stratified-charge GDI engines is reviewed, and the relative merits of lean-burn, homogeneous, direct-injection engines as an option requiring less control complexity are analyzed.
