Title:
OIL PASSAGE STRUCTURE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2023028387
Kind Code:
A
Abstract:
To provide oil passage structure of an internal combustion engine, enabling quick operation of an intake-side valve timing adjustment device after starting the internal combustion engine, thereby enabling reduction of exhaust gas and reduction of fuel consumption.SOLUTION: The oil passage structure of an engine 1 includes an intake-side head oil passage 63 for supplying oil from a main oil passage 62 to an intake-side spool valve 25, and an exhaust-side head oil passage 64 for supplying oil from the main oil passage 62 to an exhaust-side spool valve 26, the exhaust-side head oil passage 64 branches from the main oil passage 62 and is communicated with an exhaust-side in-cam-cap oil passage 66. An intake-side lash adjuster oil passage 74 and an exhaust-side lash adjuster oil passage 75 are communicated with the exhaust-side in-cam-cap oil passage 66 via a first communication oil passage 72 and a second communication oil passage 73, respectively, and a hydraulic sensor 70 is mounted to the intake-side head oil passage 63.SELECTED DRAWING: Figure 7
