OIL JET VALVE OPERATION [ZY]
id0111001179c0
• Oil pressure applied to the check-ball in the oil jet valve opens and closes the oil passageway to the nozzle and controls oil injection starting and stopping.
• Oil pressure greater than the specified value applied to the check-ball in the oil jet valve opens the oil passage to the spring-pressed nozzle, starting injection. Conversely, oil pressure less than the specified value applied to the check-ball blocks the oil passage spring force, stopping injection.
