Tree and published by . This book was released on 1994 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-cylinder measurements of soot particle size, number density and temperature have been made using optical measurements in a direct injection diesel engine. The measurements were made at one location approximately 5 mm long and 1.5 mm wide above the bowl near the head. Two optical techniques were used simultaneously involving light scattering extinction and radiation. An optical probe was designed and mounted in a modified exhaust valve which introduced a beam of light into the cylinder and collected the scattered and radiating light from the soot. The resulting measurements were semi-quantitative, giving an absolute uncertainty on the order of + or - 50% which was attributed mainly to the uncertainty of the optical properties of the soot and the heterogeneous nature of the soot cloud. Measurements at three speeds and three overall equivalence ratios were made. For all of the operating conditions the soot in the measurement volume increased in size to a maximum followed by a rapid decrease. The peak soot diameters were in a range of 30 - 50 nm. Peak soot diameter, soot volume fraction, and soot temperature appeared to increase with equivalence ratio at the measurement location. The results also suggested the soot cloud to be very dense with peak soot volume fraction near 4-6 x 10-6 and thick with a soot cloud thickness approximately 0.4 - 0.6 times the length from the piston to the head.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the emerging research centred on using methanol- whose excellent fuel properties, easy production and relative compatibility with existing technology- make it attractive to researchers looking to alternative fuels to meet the rising energy demand. The volume is divided into broadly 4 parts which discuss various aspects of the proposed methanol economy and the technological advances in engine design for the utilisation of this fuel. This book will be of interest to researchers and policy makers interested in using methanol as the principal source of ready and stored energy in societal functioning.

Available in PDF, EPUB and Kindle. Book excerpt: This study is dedicated to investigation of soot formed during combustion in diesel engine. Measurements were performed in a high speed direct injection optical diesel engine. Initially soot particle size, size distribution and soot volume fraction were investigated using time resolved laser induced incandescence (TR-LII) technique. For this study standard diesel fuel was used and measurements were performed for various injection timing and two different engine loads. Investigation showed that TR-LII is a powerful tool that can be used for characterization of in-cylinder soot in the engines. Subsequently TR-LII technique was developed to measure in-cylinder soot in two dimensional plane (planar laser induced incandescence PLII) and technique was combined with high speed imaging to investigate soot processes for ultra-low sulfur diesel (ULSD) and bio-fuel (RME). Two injection strategies of single and double injection were applied during these measurements. A high speed imaging technique was used to study the soot formation and oxidation during the combustion process within the cylinder and PLII was applied later in the stroke to study qualitatively the relative amount of un-oxidised soot that was left in the combustion chamber. In addition to PLII, TR-LII technique was used simultaneously to explore crank angle resolved variation of primary soot particle size and their size distribution during the expansion stroke. The same measurements were repeated for fuels with different composition investigating the relationship between the fuel properties and soot emission. Finally mathematical model for soot particle size and distribution width was modified by introducing assumption of multi-lognormal in-cylinder soot particle size distribution.
