Assessment of elliptic flame front propagation characteristics of hydrogen in an optically accessible spark ignition engine
Ihracska, Balazs; Wen, Dongsheng; Imran, Shahid; Emberson, David R.; Ruiz, Lina María; Crookes, Roy J.; Korakianitis, Theodosios (2013-11-22)The absence of carbon content of hydrogen fuel makes it an attractive candidates for future energy carriers. Hydrogen or dual fuelled engines are a practical alternative to pure hydrocarbon fuelling modes. However, fine ... -
Assessment of elliptic flame front propagation characteristics of iso-octane, gasoline, M85 and E85 in an optical engine
Ihracska, Balazs; Korakianitis, Theodosios; Ruiz Hincapie, Paula; Emberson, David R.; Crookes, Roy J.; Diez, Alvaro; Wen, Dongsheng (2014-03-31)Premixed fuel–air flame propagation is investigated in a single-cylinder, spark-ignited, four-stroke optical test engine using high-speed imaging. Circles and ellipses are fitted onto image projections of visible light ... -
Optical characterization of Diesel and water emulsion fuel injection sprays using shadowgraphy
Emberson, David R.; Ihracska, Balazs; Imran, Shahid; Diez, Alvaro (2016-08-31)Diesel fuel and water emulsions have been shown to reduce emissions of NOx and PM from compression ignition engines. There is a lack of work examining the influence of emulsification on the sprays formed during injection. ... -
Performance and specific emissions contours throughout the operating range of hydrogen-fueled compression ignition engine with diesel and RME pilot fuels
Imran, Shahid; Emberson, David R.; Hussain, Amjad; Ali, Hassan; Ihracska, Balazs; Korakianitis, T. (2015-09)This paper presents the performance and emissions contours of a hydrogen dual fueled compression ignition (CI) engine with two pilot fuels (diesel and rapeseed methyl ester), and compares the performance and emissions ...
