Abstract
A piston cooling apparatus of an engine and a method for controlling the same are provided. The piston cooling apparatus includes a piston cooling jet that has a first nozzle configured to spray oil towards an inner wall of a cylinder configured such that a piston reciprocates thereon, and a second nozzle configured to spray the oil towards the lower part of the piston. A jet control valve is installed to adjust a hydraulic pressure that is supplied from an oil pump to the piston cooling jet. A controller is configured to operate the jet control valve and adjust the hydraulic pressure discharged from the oil pump.
