Abstract
A hydraulic pressure warning system for an internal combustion engine including a hydraulic pressure sensor that is prevented from being influenced by the heat of the engine and by the pulsation of an oil pump. A hydraulic pressure sensor detects hydraulic pressure in a lubricating oil passage of the engine and issues a warning based on hydraulic pressure detected by the hydraulic pressure sensor when the hydraulic pressure drops. The hydraulic pressure sensor is provided on a wall surface of a water jacket of a rear cylinder block so as to project therefrom.
