Abstract: PURPOSE: A chain guide for driving a camshaft is provided to reduce power loss, and to prevent noise from backlash by straining continuously with applying constant tension in loosening a timing chain. CONSTITUTION: A camshaft driving chain guide is composed of a first guide member(20) supporting by contacting to the outside of a timing chain(10), and assembling by a fixing unit; a second guide member(30) supporting the other side of the timing chain by contacting with facing to the first guide member, and moving horizontally or vertically according to the length of the timing chain; a connecting member(40) connecting and fixing the first guide member and the second guide member; an elastic member(50) inserted between first and second guide members to apply elastic force vertically according to changes of the length of the timing chain; and a bearing member(60) turning the second guide member around the connecting member. Power loss and noise are prevented with keeping tension continuously by the elastic member and the bearing member.

Abstract: PURPOSE: A structure of an Idle Speed Control(ISC) valve passage for an internal combustion engine is provided to reduce cavity noise when air passes a bypass air passage of the ISC valve. CONSTITUTION: In a structure of an ISC valve passage for an internal combustion engine, a stepmotor valve passage and a Fast Idle Auxiliary(FIA) valve passage introduce the air bypassing a throttle valve(8) into an intake manifold(6). A lip(L) is installed in the outlet(5) of the FIA valve passage, and reduces cavity noise.
