The present invention relates to a fuel injector (16) of a dual-fuel internal combustion engine configured to supply fuel to a combustion chamber (33) of a cylinder (12) of the dual-fuel internal combustion engine. The fuel injector comprises: a main body (27); a nozzle needle (28) guided to be movable in a needle guide (30) of the main body (27); and a needle fuel chamber (31) demarcated by the main body (27) and being able to be engaged with the fuel chamber (33) of the cylinder (12) through an opening (32). The opening (32) is opened at a first position of the nozzle needle (28) and is closed at a second position of the nozzle needle (28). A first line (34) engaged with the needle fuel chamber (31) is introduced into the main body (27), and a first liquid fuel can be introduced into the needle fuel chamber (31) through the first line (34). A second line (35), which is separated from the first line (34) and is engaged with the needle fuel chamber (31), is introduced into the main body (27), and a second liquid fuel can be introduced into the needle fuel chamber (31) through the second line (35). The present invention aims to create a new type of fuel injector of a dual-fuel internal combustion engine, and a dual-fuel internal combustion engine having the fuel injector. 이중-연료 내연 기관의 실린더(12)의 연소 챔버(33)에 연료를 공급하도록 구성된 이중-연료 내연 기관의 연료 인젝터(16)로서, 본체(27)와, 본체(27)의 니들 가이드(30) 내에서 이동 가능하게 안내되는 노즐 니들(28)과, 본체(27)에 의해 획정되고, 개구(32)를 통해 실린더(12)의 연소 챔버(33)에 결합될 수 있는 니들 연료 챔버(31)를 가지며, 개구(32)는 노즐 니들(28)의 제1 위치에서 개방되고, 노즐 니들(28)의 제2 위치에서 폐쇄되고, 니들 연료 챔버(31)에 결합된 제1 라인(34)이 본체(27) 내로 도입되고, 제1 라인(34)을 통해 제1 액체 연료가 니들 연료 챔버(31) 내로 도입될 수 있고, 제1 라인(34)과는 별도이고 니들 연료 챔버(31)에 결합된 제2 라인(35)이 본체(27) 내로 도입되고, 제2 라인(35)을 통해 제2 액체 연료가 니들 연료 챔버(31) 내로 도입될 수 있다.
