Abstract

[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).
