| Outline of Final Research Achievements |
This study deals with the development of controlled-ignition technology for high performance compression ignition alcohol engines. The objective of this study is quantitative evaluation of main factors that influence auto-ignition of an alcohol spray. This study focuses on the effects of surrounding gas pressure, temperature and oxygen concentration on auto-ignition. Surrounding gas pressure and temperature dependence of the spray auto-ignition was clearly presented by the 3D-surface data of ignition delay for Ethanol-Diethyl ether blended fuels. However, the database is insufficient yet due to the rack of data indicating the effect of Oxygen concentration on ignition delay. Results obtained during these three years indicate that the engine control logic can be drawn and the high performance CI alcohol engines can be developed when the database as 3D-surface data of the ignition delay is completed.
