Research Abstract

This study has explored the possibility of combustion control in premixed charge compression ignition engines which use two different reactivity fuels.
One candidate is a system in which less reactive fuel is supplied from intake port while more reactive one is directly injected into a combustion chamber. In this system, we developed an understanding of the relation between reactivity of two fuels and overall combustion rate in a chamber and in addition, the experimental result shows that the chemical reaction of premixed fuel affect the ignition of directly-injected fuel.
Another candidate is one in which more reactive fuel is used as pre-mixture and direct injection is used to supply less reactive fuel. It is found that this system can dramatically reduce unburned emissions yielded from pre-mixture and simultaneous higher thermal efficiency and lower pollutant emissions can be achieved by combining with exhaust gas recirculation.
