Prof. Takeyuki Kamimoto from Tokyo Institute of Technology passed away on Tuesday 28 August 2018.
Prof. Kamimoto was a friend of the Italian community working on soot and on engine combustion in the late nineties. He contributed to the knowledge on the formation of soot in diesel engines both on fundamental levels and developing brilliant diagnostic tools for in-cylinder engine measurements. Are well known to the community his pioneering studies on transparent engines, the multi zone model of diesel engine combustion, his fast-sampling valve for following in-situ on the millisecond time scale the progress of the combustion process. Today these researches appear us as belonging to the archeology of the combustion researches but they opened the way to the modern measurements based on laser diagnostics.
