FUEL ADDITIVE DISPENSER WITH HEATING SYSTEM; FUEL DISPENSER WITH HEATING SYSTEM

摘要

Liquid fuel additive dispenser (102) avoiding freezing at low temperatures. A hose (120; 220; 420; 520; 620) is configured to carry fuel additive from a flow meter (116; 216; 416; 516; 616) a compartment structure with a central compartment (236; 536; 636) encloses the flow meter (116; 216; 416; 516; 616); an elongated sleeve (240, 242; 540, 542; 640, 642) coupled with the central compartment (236; 536; 636) surrounds the hose (120; 220; 420; 520; 620); a first fluid heater (244; 464) is coupled in flow connection with the compartment structure to disperse a heating fluid therein; a nozzle (222, 224; 322, 324; 422, 424; 522, 524; 622, 624) is coupled to the hose (120; 220; 420; 520; 620) and a second fluid heater (468) is coupled in flow connection with a nozzle volume (134; 334; 434) that surrounds the nozzle (222, 224; 322, 324; 422, 424; 522, 524; 622, 624).
