Abstract
An airless nozzle and fuel deliver system for a fuel-fired burner sprays fuel droplets for ignition to increase heat for regenerating an exhaust component. A source of pressurized fuel delivers pressurized fuel to a first fuel injector. In response to a first control signal, the first fuel injector is opened and fuel pressure is increased to a desired level to open a valve such that the fuel can be delivered to the airless nozzle. The airless nozzle sprays fuel droplets for a period of time that the first fuel injector is open. In response to a second control signal, the first fuel injector is closed and a second fuel injector is opened such that fuel is vented to decrease fuel pressure between the valve and the first fuel injector to stop the spray of fuel droplets by closing the valve.
