10. Opening Pressure of Piston Oil Jet Oil Pressure [kPa] Engine Speed [rpm] Lubrication System • Oil 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 decreases To Engine Parts ON Open Sleeve Valve "Rise" From Oil Pan

11. Opening Pressure of Piston Oil Jet Oil Pressure [kPa] Engine Speed [rpm] 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 increases To Engine Parts OFF Close Sleeve Valve "Down" Relief valve spring is compressed by sleeve valve From Oil Pan
