Design and Experimental Characterization of Electrostatically Assisted Automotive Fuel Injectors
With current automotive fuel injector designs, fuel mass and momentum cannot be independently controlled during engine operation. By introducing electrostatic charge to the fuel as it is injected, a means of altering the injector spray pattern without changing the mass injected is available. A …
