A cooling pipe for an internal combustion engine includes with a resin-made water outlet for forming a circulation path for circulating a coolant for cooling an engine body, and an attachment part for retaining a water temperature sensor for sensing the temperature of the coolant flowing through the water outlet, the attachment part being attached to the water outlet, a portion of the attachment part being in contact with the engine body, and the attachment part formed from a material whereby heat from the engine body is transmitted.

Structure for retaining temperature sensing device and internal combustion engine provided with same

The fuel pump driving structure includes a camshaft and a pump cam member. The camshaft is rotatably supported at an end by a cylinder head. The pump cam member has a fitting hole into which the end of the camshaft is press fitted, and is operatively coupled to a high-pressure fuel pump. The pump cam member includes a pump cam section and a first contact section. The pump cam section has a first lift portion operating the high-pressure fuel pump, and a base circular portion that does not operate the high-pressure fuel pump. The first contact section is in a position offset from a position of the first lift portion with respect to a circumferential direction and contacting a portion of the camshaft in an axial direction at a position radially outward of an external circumferential surface of the one end of the camshaft.
