The engine performances and exhaust gas characteristics of prechamber-type compression ignition engines operated with a composite emulsified fuel made of gas oil, methanol (or ethanol) and water were investigated. As a result, the thermal efficiency under composite emulsified fuel operation was found to be of the same level as that under gas oil operation. The methanol (or ethanol) distributed in the gas oil promoted the diffusion combustion duration, which indicated the shortened total combustion duration. Therefore, the maximum thermal efficiency was achieved at a slightly advanced timing of injection as compared to the water/gas oil emulsified fuel operation. The NO_x and smoke emission with the composite emulsified fuel operation was reduced to about a half of that of the gas oil operation with the same level of engine noise.
