This article reports on research performed to lower the thermal stress in diesel engines by adding water to the fuel, and to raise the engine economy level by improving the mixture formation and combustion processes. The optimal water content for each diesel engine, operated at rated power and speed, was determined, corresponding to the lowest specific fuel consumption when operating on the straight fuel. The effects of additives to the water-fuel emulsion on the operation of the engines were investigated. High-speed motion picture photography was used to investigate the combustion process of the water-fuel emulsion. The results of the study of thermal stress in diesel engines indicate that, with a combustion rate of 30-35%, the temperature of the head surface exposed to the flame is lowered by 8-10/sup 0/C, whereas the exhaust temperature is lowered quite sharply.
