In-cylinder gas flow, spray and combustion processes are measured with ultra high-speed imaging, spectroscopy of emissions from chemical reactions, and lasers. Furthermore, CFD simulations are performed to predict and to elucidate those processes. Effective use of hydrogen, e-fuels and bio-fuels that contribute to carbon neutrality are also targeted.<\/span><\/p>\n<ul>\n<li><a href=\"https:\/\/www.cc.okayama-u.ac.jp\/hpl\/\">Link to group homepage<\/a><\/li>\n<\/ul>\n<table class=\"el_table_fix\" style=\"width: 100%\">\n<tbody>\n<tr>\n<th style=\"width: 20%\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium\" src=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas08_advmech\/KAWAHARA Nobuyuki.jpg\" width=\"320\" height=\"408\"><\/th>\n<td style=\"width: 80%\">\n<ul>\n<li style=\"list-style-type: none;font-size: 12px;margin-left: -20px\"><span style=\"font-size: 12pt\">Prof. KAWAHARA Nobuyuki<\/span><\/li>\n<li style=\"list-style-type: none;font-size: 12px;margin-left: -20px\"><span style=\"font-size: 12pt\">E-mail: <span id=\"content_ousdb1_lp$002fitem$005b1$005d$002fsys_mail\">kawahara <span style=\"color: #0000ff\">[at]<\/span> <\/span>cc.okayama-u.ac.jp<\/span><\/li>\n<li style=\"list-style-type: none;font-size: 12px;margin-left: -20px\"><span style=\"font-size: 12pt\">Thermal Engineering, Internal Combustion Engine, Combustion, Laser Diagnostic, Numerical Simulation\n<p><\/span><\/li>\n<\/ul>\n<p><span style=\"font-size: 12pt\"><a class=\"el_linkBtn\" href=\"https:\/\/soran.cc.okayama-u.ac.jp\/html\/8fda401257ba124174506e4da22f6611_en.html\">Directory of Researchers<\/a>&nbsp;<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h5>Development of hydrogen engine<\/h5>\n<div style=\"width: 640px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-476-1\" width=\"640\" height=\"360\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas08_advmech\/img_KAWAHARA.mp4?_=1\" \/><a href=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas08_advmech\/img_KAWAHARA.mp4\">https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas08_advmech\/img_KAWAHARA.mp4<\/a><\/video><\/div>\n<p><span style=\"font-size: 10pt\">Combustion in hydrogen engine<\/span><\/p>\n<p>Electric power generators (gas engine) with hydrogen as fuel have been developed.
