16 Opening Pressure of Piston Oil Jet Lubrication SystemOil Pump (Electrically Variable Oil Pressure Type)Oil Pressure Control (Low Pressure)When the ECM turns the oil pressure switching valve ON, sleeve valve and relief valve upward. As a result, opening pressure of relief valve decreasesTo Engine PartsONEngine Speed [rpm]Oil Pressure [kPa]Opening Pressure of Piston Oil JetOpenSleeve Valve "Rise"When the ECM turns the oil pressure switching valve ON, oil pressure is applied to the lower portion of the sleeve valve. This pushes the sleeve valve upward and moves the oil passage provided on the side of the sleeve valve upward also. At the same time, the relief valve is moved upward by the force of the relief valve spring. As a result, the opening pressure of the relief valve decreases and the engine oil pressure is controlled to a lower level.[Reference Oil Pressure]80 to 180 kPa (0.8 to 1.8 kgf/cm2, 12 to 26 psi)From Oil Pan
17 Lubrication System Oil Pump (Electrically Variable Oil Pressure Type) Oil Pressure Control (High Pressure)When the ECM turns the oil pressure switching valve OFF, relief valve spring is compressed by sleeve valve. As a result, opening pressure of relief valve increasesTo Engine PartsOFFEngine Speed [rpm]Oil Pressure [kPa]Opening Pressure of Piston Oil JetCloseSleeve Valve "Down"When the ECM turns the oil pressure switching valve OFF, no oil pressure is applied to the lower portion of the sleeve valve. The oil pressure of the oil pump pushes the sleeve valve downward while compressing the relief valve spring together with the relief valve. Consequently, the oil passage provided on the side of the sleeve valve is moved downward as well. As a result, the opening pressure of the relief valve increases and the engine oil pressure is controlled to a high level.[Reference Oil Pressure]120 to 430 kPa (1.2 to 4.4 kgf/cm2, 17 to 62 psi)Relief valve spring is compressed by sleeve valveFrom Oil Pan

28 Cooling System Coolant Passage After warm-up circulation A bypass valve is located on the water inlet housingThe coolant circulation system has been changed so that coolant only flows through the reservoir tank after the engine has warmed up.The coolant circulation system has been changed so that coolant flows from the reservoir tank to the upstream side of the thermostat instead of to the downstream side, thereby reducing the amount of cold coolant flowing while the engine is warming up. By doing this, engine warm-up performance has been increased and fuel economy has been improved.
