The engine performance and emission characteristics of a high speed diesel engine operated on water emulsified fuel were experimentally investigated. The experiments were carried out by using two types of diesel engines: a disesl engine with non-insulated combustion chamber and an experimental engine with insulated combustion chamber (with ceramic wall) . Water emulsified fuels containing water of up to 5 0 vol.% were evaluated by the two types of diesel engines.<BR>Higher temperature of working gas and higher surface temperature of combustion chamber walls were obtained by the insulated chamber engine.<BR>This paper describes the results and some findings obtained through the experiments burning water emulsified fuels with a conventional diesel engine and an adiabatic diesel engine.<BR>The experiment proves that:<BR>Combustion at higher operating temperature in an adiabatic engine results in significant changes in combustion and emission characteristics, compared that of a conventional diesel engine. NOx and smoke emission are greatly and simultaneously reduced without increasing specific fuel consumption rate by the use of water emulsified fuel and an insulated combustion chamber.
