We have previously reported that reductions in specific fuel consumption of a diesel engine achieved by using emulsions depended on the base fuel properties, the type of combustion chamber, load conditions, the type of injection, injection timing, and water content. In this paper, the effect of cooling loss on specific fuel consumption was investigated by calculating the cooling loss φw from the gas pressure in the cylinder and the φc obtained from the circulation water flowing through the water jacket of the engine. It was confirmed that compared with water-free fuel, specific fuel consumption of emulsified fuel showed a decrease with decreasing cooling loss φw and φc.
