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 ... -
Characteristics of Pressure Wave in Common Rail Fuel Injection System of HSDI Diesel Engines
Herfatmanesh, Mohammad; Peng, Zhijun; Ihracska, Balazs; Li, Yuzhen; Lu, Lipeng; Zhang, Chi (2016-05-24)The latest generation of HPCR equipment now provides diesel engines possibility to apply as many as eight separate injection pulses within the engine cycle for reducing emissions and for smoothing combustion. With these ... -
A Generalised Multiple-Mass Based Method for the Determination of the Live Mass of a Force Transducer
Montalvao, Diogo; Baker, Thomas; Ihracska, Balazs; Aulaqi, Muhammad (2017-01-15)Many applications in Experimental Modal Analysis (EMA) require that the sensors’ masses are known. This is because the added mass from sensors will affect the structural mode shapes, and in particular its natural frequencies. ... -
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. ... -
Opto-mechanical design for sight windows under high loads
Ihracska, Balazs; Crookes, Roy James; Montalvão, Diogo; Herfatmanesh, Mohammad Reza; Peng, Jun; Imran, Shahid; Korakianitis, Theodosios (2017-03-05)In this study, the design aspects of optically accessible pressure vessels are investigated via a case study of a High Pressure Combustor experimental rig. The rig was designed to take optical measurements of combustion, ... -
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 ...
