ABSTRACT:
In a combustor carburetor device having a secondary swirler which axially introduces airflow between the venturi and a splashplate, a cylindrical sleeve is inserted between the venturi and the splashplate to axially extend the air outer flow path. The cavity defined by the axial extension and the splashplate is then purged by a source of air such that the combination prevents the flow of fuel from the venturi to the surface of the splashplate to thereby reduce emissions during engine idle operation. At the downstream end of the cylindrical sleeve is attached a frustoconical portion which allows controlled dispersion of the fuel/air mixture for resultant improved ignition characteristics.
