Abstract

피스톤의 승강하는 실린더의 보어와 이의 실린더 보어 외측으로 냉각수가 순환되는 워터자켓이 형성되고, 하측으로 크랭크 실의 상측을 형성하는 스커트와 상기 실린더 보어의 중심부 직하방의 스커트 크랭크샤프트 실린더 블록에 회전 가능하게 지지하여 주는 상측 축수부가 리브로서 실린더 블록의 하측과 스커트와 연결되는 공지의 실린더 블록에 있어서, 상기 상측 축수부에 메인저어널 캡을 체결하는 볼트와 실린더블록의 상측에 실린더 헤드를 고정하는데에 체결되는 헤드 볼트의 축방향과 일직선이 되도록 형성하고, 상기 축수부의 양측단을 스커트 부분과 연결하여 주는 리브의 내측부 하부에 적정 크기의 요입부를 형성하며, 상기 스커트의 하측에 래더프레임을 배치하여서 된 저소음용엔지의 실린더 블록체를 제공함으로써, 연소과정에서의 폭발압에 의한 진동이 엔진 실린더 블록의 스커트 부분에 전달되는 것을 최소화하고, 경량으로 형성된 래더 프레임을 실린더 블록 스커트 부분의 하측에 배치하여 이에 전달되는 진동을 억제하여 소음 발생을 최소화 한 것이다.A water jacket for cooling water circulated to the outside of the cylinder bore and the cylinder bore of which the piston is lifted and formed is rotatable to a skirt forming the upper side of the crank seal below and a skirt crankshaft cylinder block directly below the center of the cylinder bore. In a known cylinder block in which an upper bearing portion to be supported is connected to a lower side of a cylinder block and a skirt as ribs, a bolt for fastening a main journal cap to the upper bearing portion and a cylinder head are fixed to an upper side of the cylinder block. It is formed so as to be in line with the axial direction of the head bolt to be formed, and the recessed portion of the appropriate size is formed in the lower portion of the inner portion of the rib that connects both ends of the bearing portion with the skirt portion, the low noise by arranging a ladder frame under the skirt By providing the cylinder block body of the engine, in the combustion process The vibration caused by the explosion pressure is minimized to be transmitted to the skirt portion of the engine cylinder block, and a lightweight ladder frame is disposed under the cylinder block skirt portion to minimize the generation of noise by suppressing the vibration transmitted thereto.
