摘要： An apparatus for controlling a piston cooling oil jet may include a main gallery supplied with oil, an oil jet gallery defining an oil injection path such that the oil through the main gallery is introduced and is sprayed to a lower portion of a piston, an oil jet valve opening the oil injection path such that the oil supplied to the main gallery is introduced into the oil jet gallery, and a controller electrically connected to the oil jet valve, and determining a target oil pressure through a first factor value corresponding to an RPM and an engine load, a second factor value determined by a predetermined target oil pressure curve, and a third factor value corresponding to an RPM and an oil temperature in the main gallery to control an opening degree of the oil jet valve using the target oil pressure.
