    摘要： [Problem to be Solved]
    To provide an oil passage structure of an internal combustion engine (1) that can quickly operate an intake-side valve timing adjustment device (15) after starting the internal combustion engine (1), making it possible to reduce exhaust gas and reduce fuel consumption.
    [Solution]
    In an oil passage structure of an engine (1), a main oil passage (62) and an exhaust-side head oil passage (64) extend upward toward an exhaust-side cam cap internal oil passage (66) from below the exhaust-side cam cap internal oil passage (66), an intake-side head oil passage (63) includes a first intake-side head oil passage (63A) extending toward an intake-side wall (4B) of a cylinder head (4) from a main oil passage (62) and a second intake-side head oil passage (63B) extending upward from an outer end portion (63a) in a direction in which the first intake-side head oil passage (63A) extends and leading to an intake-side cam cap internal oil passage (65), and the second intake-side head oil passage (63B) is provided with a sensor attachment boss (69) that attaches a hydraulic pressure sensor (70).

    摘要： The valve mechanism (1000) includes a valve (103), a camshaft (101), a fixed support (108), an intermediate swing arm (106) and a supporting base (107). The fixed support (108) is provided with a connecting-portion via hole (204) running from top to bottom, two oil passages (205) are defined in a connecting portion (201), and each of the oil passages (205) is connected with the connecting-portion via hole (204) and a corresponding intermediate swing arm shaft hole (203). The supporting base (107) defines first and second oil feeding passages (303, 304) therein, the first supporting-base oil feeding passage (303) is communicated with the connecting-portion via hole (204), and an upper end of the second supporting-base oil feeding passage (304) extends to a base-body camshaft supporting portion (302) of the supporting base (107). An engine and a vehicle are also provided. During practical use, the valve mechanism has more compact structure, ensure pressure of the lubricating oil, and meets cooling and lubricating requirements of the parts.
