A method of operating a diesel engine which overcomes problems encountered during use of a low cetane fuel with long ignition delays is disclosed. The method provides for a staged injection of an emulsified diesel fuel into the combustion chamber of the diesel engine. In particular, the method includes the steps of (A) injecting a pilot volume of an emulsified diesel fuel into a combustion chamber of the diesel engine, wherein the emulsified diesel fuel includes water and diesel fuel, (B) compressing the pilot volume of the emulsified diesel fuel within the combustion chamber during a compression stroke of the diesel engine, and (C) injecting a main volume of the emulsified diesel fuel into the combustion chamber of the diesel engine, whereby heat generated by compression of the pilot volume of the emulsified diesel fuel causes the pilot volume of the emulsified diesel fuel to combust so as to ignite the main volume of the emulsified diesel fuel. |
