Abstract: A cylinder head cover structure is provided to prevent a blow-by gas reduction apparatus from freezing, by preventing a blow-by gas flow chamber arranged in a cylinder head cover from directly contacted with outdoor air and preventing heat exchange between blow-by gas flowing through a blow-by gas flow chamber and outdoor air existing outside the blow-by gas flow chamber. A cylinder head cover(11) has a blow-by gas flow chamber(12) and an outdoor air inlet chamber(13). A heat insulation air chamber(15) for heat insulation of the blow-by gas flow chamber is formed in front of the blow-by gas flow chamber. The chambers include protrusions(11a) formed on the cylinder head cover, and baffle plates(11b) formed at the bottoms of the protrusions. The heat insulation air chamber and the blow-by gas flow chamber are separated from each other by a separation wall(14).

Abstract: PURPOSE: A connection structure of a timing chain is provided to shorten repairing time by removing a process for dismantling a front cover of an engine in repairing and replacing a cam shaft and a valve train. CONSTITUTION: In a timing chain(30) of an engine, inside and outside links(31,32) are coupled to each other by a fixing pin(33) to connect a crankshaft sprocket and a cam shaft sprocket to transmit power of the crank shaft to a cam shaft. A pin hole(35) is formed in the middle of a connection fixing pin(34) for shaft-supporting shaft holes of the inside and outside links. A split pin(40) is inserted into the pin hole to prevent separation. The split pin is folded in two. A circular knob unit(41) is disposed at one end of a folded portion. An insertion unit(42) is formed in a straight line at one end of the other separated portion. The insertion unit is fitted into the pin hole, then bent to both sides, and not taken out of the pin hole.

Abstract: 본 발명은 소음 개선을 위한 실린더헤드 커버구조에 관한 것으로서,
종래의 실린더헤드 커버구조는 챔버 내부로 유입된 소음이 일측의 격벽으로 진행하고, 그 진행된 소음이 격벽에 부딪혀 반사될때 그 소음과 반사파가 서로 중첩되면서 오히려 소음 레벨이 증가하는 문제점이 발생하고 있었다.
따라서, 상기 문제점을 해결하기 위한 본 발명은 실린더헤드의 커버케이스 내측에 형성된 챔버의 격벽에 일정각도 경사지게 반사판을 형성하므로서, 챔버 내를 유동하는 소음과 그 소음의 반사파가 서로 중첩되지 않도록 하여 전체적인 소음레벨이 감소되도록 하고, 반사판이 보강리브의 역할을 하도록 하여 실린더헤드 커버의 강도가 보강되도록 한 소음 개선을 위한 실린더헤드 커버구조에 관한 것이다.

Abstract: PURPOSE: A cylinder head cover structure is provided to reinforce the strength of a cylinder head cover by preventing flowing noise inside a chamber and reflecting waves of the noise. CONSTITUTION: A reflecting plate(30) is formed in one partition(3) of a chamber(2) by inclining at a certain angle to reflect reflecting waves of noise for preventing the overlapping with noise waves. The reflecting plate is inclined toward both sidewalls from the center of the partition. Thereby, the entire noise level is reduced by preventing the overlapping between the flowing noise inside the chamber and the reflecting waves of the noise. Moreover, the strength of a cylinder head cover is reinforced by functioning the reflecting plate as a reinforcing rib.
