This paper deals with quantitatively the influence of water emulsified fuel on combustion, engine vibration and noise, and the effect of ignition improver on the reduction of vibration and noise. The main conclusions obtained are as follows : (1) With an increase in the water addition rate, ignition delays and the maximum pressure rise rate increases. As a result, engine vibration and noise increase, in proportion to the pressure rise rate. (2) An increase in ignition delay with the addition of water is closely related to the heat quantity required to evaporate water in the fuel spray under a high temperature and high pressure condition. (3) Increases in engine vibration and noise due to the addition of water can be reduced by adding a small amount of ignition improver without aggravating engine performance.
