엔진(E)의 실린더블록(B) 프론트측에 무빙부품인 피스톤(P)과 콘로드(CR)와 피스톤핀을 냉각시킬 수 있는 오일젯(OJ)이 설치된 것에 있어서,In the front of the cylinder block B of the engine E, the piston P, the moving rod CR, and the oil jet OJ for cooling the piston pin are installed.
상기 엔진(E)의 실린더블록(B) 하부리어측에 오일분사구(10)을 각 기통마다 설치하여 무빙부품을 냉각시킬 수 있게 한 것이다.The oil injection port 10 is installed in each cylinder at the lower rear side of the cylinder block B of the engine E to cool the moving parts.
이와 같이 구성된 본 발명의 일 실시예를 상세하게 설명하면 다음과 같다.Referring to one embodiment of the present invention configured as described in detail as follows.
도면 도 2에서 보는 바와 같이 엔진(E)의 실린더블록(B) 중앙에 무빙부품인 피스톤(P)과 콘로드(CR)가 피스톤핀에 의해 연결설치되고, 하부에는 크랭크(C)을 설치한다.As shown in FIG. 2, the piston P, which is a moving part, and the cone rod CR are installed at the center of the cylinder block B of the engine E by a piston pin, and a crank C is installed at the lower portion thereof. .
상기 실린더블록(B)의 프론트측에 밸브(V)을 가진 오일젯트(OJ)을 설치하고, 리어측에는 각 기통마다 오일분사구을 설치한다.An oil jet (OJ) having a valve (V) is provided on the front side of the cylinder block (B), and an oil spray port is provided for each cylinder on the rear side.
상기 오일분사구(10)를 실린더블록(B)에 형성한 메인갤러리(MG)와 연통되는 토출공(H)을 실린더블록(B)의 보어(BR)에 형성시키고, 토출공(H)에는 밸브(V')을 설치한 것이다.A discharge hole (H) communicating with the main gallery (MG) formed in the cylinder block (B) is formed in the bore (BR) of the cylinder block (B), the valve in the discharge hole (H) (V ') is installed.
이와 같이 된 본 발명의 작용 및 효과를 상세하게 설명하면 다음과 같다.Referring to the operation and effects of the present invention as described above in detail.
내연기관의 엔진(E)이 구동하면 연소실에서 발생한 연소가스에 의해 엔진(E)의 실린더블록(B)과 피스톤(P)과 콘로드(CR)은 피스톤핀이 고열을 받아 온도가 상승한다.When the engine E of the internal combustion engine is driven, the cylinder block B of the engine E, the piston P, and the cone rod CR of the engine E are heated by the combustion gas generated in the combustion chamber, and the temperature rises.
이때 실린더블록(B)의 온도상승으로 압력이 높아지면 설치한 오일젯(OJ)과 오일분사구(10)의 밸브(V') 작동한다.At this time, when the pressure increases due to the temperature rise of the cylinder block (B), the oil jet (OJ) and the valve (V ') of the oil injection port 10 is operated.
밸브(V')가 작동하면 오일젯(OJ)의 밸브(V)와 오일분사구(10)의 밸브(V')을 통해 메인갤러리(MG)에서 유입된 오일이 실린더블록(B)의 보어(BR)에 공급된다.When the valve V 'is operated, the oil introduced from the main gallery MG passes through the valve V of the oil jet OJ and the valve V' of the oil injection hole 10 so that the bore of the cylinder block B BR).
따라서, 보어(BR)내에 공급된 오일에 의하여 무빙부품인 피스톤(P)과 콘로드(CR)와 피스톤핀등을 냉각시키도록 한 것이다.Therefore, the piston P, the cone rod CR, the piston pin, etc., which are the moving parts, are cooled by the oil supplied in the bore BR.
이러한 오일분사구(10)는 각 기통마다 설치하여 온도상승에 따른 압력이 높아지면 오일을 보어(BR)내에 공급시켜 무빙부품을 냉각시키므로써, 엔진(E)의 냉각 효율을 증대시킨다.The oil injection port 10 is installed in each cylinder to increase the cooling efficiency of the engine E by supplying oil into the bore BR to cool the moving parts when the pressure according to the temperature rises.
이상에서와 같이 본 발명은 무빙부품(콘로드, 피스톤핀, 피스톤)을 냉각시키는 오일분사구을 실린더블록의 리어측 각 기통에 설치하여 무빙부품을 냉각시키므로써, 엔진의 냉각 효율을 높일 수 있도록 하므로써, 엔진의 냉각 효율을 증대시키고, 엔진의 작동상승 및 내구수명을 증대시킬 수 있는 효과가 있다.As described above, the present invention installs an oil spray port for cooling moving parts (cone rod, piston pin, piston) in each cylinder of the rear side of the cylinder block to cool the moving parts, thereby improving the cooling efficiency of the engine. There is an effect that can increase the cooling efficiency of the engine, increase the operation rise and durability life of the engine.
