Abstract:
The now field of a sinde injection water raInjet was calculated based on the model which was established in the p印er．Efkcts of chamber length，wate卜fuel ratio and droplet size on combustion stability were resea_rched．It is shown that increasing chamber length，multiple water injection to decrease local water—fuel ratio and choosing pmper atomizer wiU benifit combustion stabi— lity．
