るエンジンの潤滑装置。 A piston cooling oil jet nozzle with an injection port facing the piston and a liner lubrication oil jet nozzle with an injection port facing the inner peripheral surface of the cylinder liner are provided, and are connected to the oil gear gallery of the cylinder block. When the oil pressure in the oil gear rally is equal to or higher than the first set pressure, the piston cooling oil jet nozzle and the oil gear are communicated, and the oil pressure in the oil gear is set to a second set pressure higher than the first set pressure. In the above case, the engine lubricating device is further provided with an oil jet adjusting means for communicating the liner lubrication oil jet nozzle and the oil gear gallery.
