PURPOSE: A smoke from an exhaust gas of a diesel engine is reduced, and engine structure is simplified. CONSTITUTION: An injector has a nozzle portion(110) to inject fuel, a holder portion(150) to supply fuel to the nozzle portion, and a needle to open the nozzle. A fuel heating member(130) is installed around the needle to heat fuel. A connector portion is installed in the holder portion to supply power. The fuel heating member(130) comprises a heating coil wound around the needle to radiate heat when applied with an electrical current.
