  1. KEIOUNIVERSITY The Study on Auto-ignition and Combustion Process of the Fuel Blended with Methane and DME in HCCI Engine Susumu Sato, Daisuke Yamashita, Junpei Ozaki, Azusa Ito Purpose We use the Fuel blended with Methane and DME and search the effect of mixing ratio on ignition temperature and ignition timing . Experiment system 4 stroke engine DME Methane 623 Results Qin=960J const fCH4=0.1 const fDME=0.1 const ・ Ignition timing and RHR peak timing became later （faster） by increasing Methane （DME）ratio. ・ Peak pressure became lower by delaying RHR peak timing. 2005 IIDA LABORATORY
