Zusammenfassung:	Disclosed is a fuel spraying apparatus. The fuel spraying apparatus according to an embodiment of the present invention may comprise: an engine including a plurality of combustion chambers generating a driving force by combustion of a fuel; a piston reciprocating up and down in the combustion chamber of the engine; a fuel separation device which separates the fuel stored in a main fuel tank into a low-octane fuel and a high-octane fuel according to an octane number; a main injector spraying the low-octane fuel separated by the fuel separation device into the combustion chamber; and an auxiliary injector for spraying the high-octane fuel separated from the fuel separation device into the combustion chamber at an injection angle smaller than the same of the main injector in the vertical direction. An objective of the present invention is to provide the fuel spraying apparatus for the engine capable of suppressing knocking from occurring in the combustion chamber. 연료 분사 장치가 개시된다. 본 발명의 실시 예에 따른 연료 분사 장치는 연료의 연소에 의해 구동력을 발생시키는 복수의 연소실을 포함하는 엔진; 상기 엔진의 연소실 내부에서 상하 왕복 이동하는 피스톤; 메인 연료 탱크에 저장된 연료를 옥탄가에 따라 저옥탄 연료와 고옥탄 연료로 분리하는 연료 분리 장치; 상기 연료 분리 장치에서 분리된 저옥탄 연료를 상기 연소실로 분사하는 메인 인젝터; 및 상기 메인 인젝터의 분사 각도보다 수직 방향으로 작은 분사 각도로 상기 연료 분리 장치에서 분리된 고옥탄 연료를 상기 연소실로 분사하는 보조 인젝터;를 포함할 수 있다.
