The purpose of this study is to clarify the influence of water contents in emulsified fuel on compression ignition engine performance, and to compare the engine performance of water injection method. In the water injection method, the water was supplied to the intake manifold by electric injector and diesel fuel was injected into cylinder. Two emulsified fuels of which mixing ratio of water were 15vol.% and 30vol.% were tested. The ignitability of emulsified fuel was inferior to that of diesel fuel and the ignition timing of emulsified fuel which contained large amount of water delayed. The thermal efficiency of emulsified fuel was slightly lower than that of the diesel fuel, however the exhaust gas emissions of NOx and smoke were reduced. The engine performance of water injection method was similar to that of the diesel fuel, however the NOx emissions was reduced because of the combustion temperature reduction by water evaporation.
