Abstract

Using three-dimensional simulation software AVL FIRE establish a direct injection diesel model.Analyzes the effects of water content of emulsified diesel on the combustion progress of diesel engine.The results showed that with the diesel water content increasing, the maximum cylinder pressure generally declining until can not ignite.When water content is 3%,the maximum cylinder pressure increased slightly about 0.15%. Heat release rate curve further up the TDC and increase cycle work while reducing the compression work so that the combustion process can completed in advance; fuel consumption rate keep rising as the water porperty rising.However, after deducting the corresponding proportion of water, fuel consumption rate showed shrinking tendency, and fuel consumption to a minimum rate of 25% under aqueous conditions, fuel consumption rate reduce by 6.06% compared with the fuel not mixed with water.
