The Study on Auto-ignition and Combustion Process
of the Fuel Blended with Methane and DME in HCCI
Engine

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
Qin960J const
fCH40.1 const
fDME0.1 const
Ignition timing and RHR peak timing became
later (faster) by increasing Methane (DME) ratio.
Peak pressure became lower by delaying RHR
peak timing.
