OIL JET VALVE CONSTRUCTION [LF, L3]
id0111001178b5
• The oil jet valves are installed in the cylinder block (in the main journal). The piston cooling efficiency by oil injected from the nozzles has been improved by the attachment direction of the oil jet valves which are pointed toward the back surface of each piston.
• The oil jet valves have been designed to maintain optimum oil pressure in the engine by controlling the oil injection depending on the oil pressure on the oil jet valves.
