Abstract:
A method of operating a diesel engine, with the diesel engine having (i) a combustion chamber, and (ii) a fuel injector having an injection port positioned in fluid communication with the combustion chamber, comprising the steps of:injecting a pilot volume of an emulsified diesel fuel into said combustion chamber with said fuel injector;compressing said pilot volume of said emulsified diesel fuel within said combustion chamber during a compression stroke of said diesel engine; andinjecting a main volume of said emulsified diesel fuel into said combustion chamber with said fuel injector, whereby heat generated by compression of said pilot volume of said emulsified diesel fuel causes said pilot volume of said emulsified diesel fuel to combust so as to ignite said main volume of said emulsified diesel fuel.
