Abstract:

This study deals with the development of compression ignition DI alcohol engine with higher efficiency and lower emissions comparing to the conventional internal combustion engines. In order to establish such high performance alcohol engines, development of controlled ignition technology is required. This paper focuses on the main factors that govern auto-ignition phenomenon of alcohol spray from the view point of fuel properties. The reason of poor auto-ignition quality of alcohol spray was theoretically and experimentally revealed. That is difficulty of simultaneous attainments of ignition-suitable concentration and temperature in a spray mixture formation due to their smaller stoichiometric air/fuel ratio and larger latent heat for evaporation in comparison with conventional diesel fuels.
