Japanese Patent JP7099120

B2

Provided is a vehicle internal combustion engine capable of suppressing deformation and vibration of a chain cover due to vibration of the vehicle internal combustion engine, and capable of preventingreduction of detection precision of a sensor. In an engine (5), a chain cover (21) is provided with: an oil pump unit (23) provided to the lower part of the chain cover (21); a sensor boss part (31)provided at the upper part of the chain cover (21); and cylindrical oil passage sections (24, 25). The oil passage sections (24, 25) are formed in a cylindrical shape. The oil passage section (24) hasan oil passage (24a) that communicates with the oil pump section (23) and extends upward from the oil pump section (23), and the oil passage section (25) has an oil passage (25a) that communicates with the oil passage (24a) and extends in the horizontal direction from the oil passage section (24). The sensor boss section (31) is provided in a connection section (26) that connects the oil passagesection (24) and the oil passage section (25), and the sensor (32) detects the state of oil flowing through the oil passages (24a, 25a). The sensor boss section (31) is provided in the connection section.
