Abstract
An exhaust pipe fuel injector capable of preventing fuel from remaining in a fuel supply system and thus capable of preventing the fuel supply system from being blocked due to carbonization of the fuel, is provided. The exhaust pipe fuel injector includes: a fuel injection nozzle that injects the fuel into an exhaust pipe; a supply pipe through which a mixed fluid of the fuel and air is supplied into the fuel injection nozzle; and a control unit. The control unit has a function of continuing combustion until no fuel remains in the inside of the supply pipe during regeneration of a diesel particulate filter.
