ZUSAMMENGESETZTE NOCKENWELLE UND MIT DER ZUSAMMENGESETZTEN NOCKENWELLE VERSEHENER VERBRENNUNGSMOTOR

摘要

The degree of freedom in a mounting position of a fuel pump driving cam (115) is improved by making valve operating cams (130R) separate members from a camshaft main body (30R) and mounting the valve operating cams (130R) from the outside in the axial direction of the camshaft main body (30R) after mounting the fuel pump driving cam (115) onto the camshaft main body (30R). Also, the valve operating cams (130R) are formed of solid phase sintered material while the fuel pump driving cam (115) is formed of liquid phase sintered material.
