APPLICABLE VEHICLE AND PRODUCT INFORMATION 1.1 Introduction As a result of a model change, TOYOTA's first V-8 engine, the "1VD-FTV" has been installed in the TOYOTA LAND CRUISER (200 series). This manual describes the Common Rail System (CRS) installed on the LAND CRUISER (200 series) 1VD-FTV engine. For common information to all CRSs, refer to the previously published CRS general addition manual (Doc ID: 00400076E). [Items common to all CRSs: CRS development process, system control, construction and operation of main components (supply pump, rail, injectors), sensors and actuators.] 1.2 Applicable Vehicle Vehicle Name LAND CRUISER (200 Series) Vehicle Engine Engine Model Model Displacement VDJ200 1VD-FTV 4.5L Destination Europe, Australia, Russia, Middle East, General Release Date August. 2007 Operation Section 1.3 Layout of Main Components 1 2 Operation Section 1 3 1.4 Applicable Product List Parts Name DENSO Part Number Manufacturer Part Number 294050-023# 22100-51030 294050-024# 22100-51040 095000-673# 23670-51020 8 injectors HU095440-100# 23810-0W010 RH HU095440-104# 23820-0W010 LH 275900-002# 89661-60F60 AT, Europe 275900-003# 89661-60F70 AT, Australia, Russia 275900-004# 89661-60F80 AT, General, Middle East 275900-005# 89661-60F90 AT, General 275900-006# 89661-60G00 AT, EGR, General 275900-007# 89661-60G10 AT, General, Middle East 275900-008# 89661-60G20 MT, General 275900-009# 89661-60G30 MT, EGR, General EDU 101310-578# 89870-60070 2 EDUs Crankshaft Position Sensor 029600-074# 90919-05029 Cylinder Recognition Sensor 029600-149# 90919-05072 Coolant Temperature Sensor 071560-005# 89422-16010 Accelerator Pedal Module 198800-359# 78120-60410 EGR Valve No.1 135000-727# 23620-51010 RH EGR Valve No.2 135000-728# 25630-51010 LH Supply Pump Injector Rail Engine ECU Remarks HP4 Operation Section 1 4 1.5 CRS Construction The illustration below is an outline of the CRS. The primary feature of this system is the use of two rails and two EDUs in order to comply with the V-8 engine. When looking into the engine compartment from the driver's seat, the two rails are positioned above the right and left banks (hereafter: right bank rail = "rail RH", left bank rail = "rail LH"). EDU No.1 and No.2 each control four injectors. Operation Section 1 5 2. SUPPLY PUMP 2.1 Outline The CRS used in the TOYOTA LANDCRUISER (200 Series) is equipped with an HP4 supply pump. Supply Pump Specifications Item Content Plunger Diameter Ø8.5 × 3 Cam Lift 8.8 mm Rotation Clockwise viewed from drive side SCV Terminal Resistance 2.10 ± 0.15 (Rated Voltage) 12 V Control Type Normally closed (20 C) Operation Section 2.2 Suction Control Valve (SCV) A conventional normally closed type SCV has been adopted for use with the 1VD-FTV engine. Operation Concept Diagram Operation 1 6 1 7 Operation Section 3. RAIL 3.1 Outline Rail RH is provided with a fuel inlet for connection with rail LH. Rail internal fuel pressure is controlled by a rail pressure sensor (Pc sensor) attached to rail RH, and the engine ECU. In addition, when rail internal pressure becomes abnormally high, a pressure limiter attached to rail LH opens to release excess pressure. Operation Section 1 8 4. INJECTOR 4.1 Outline As shown in the figure below, the CRS used in the TOYOTA LANDCRUISER 70 is equipped with eight solenoid injectors with QR codes. 1 9 Operation Section 5. CONTROL SYSTEM 5.1 Control System Diagram < NOTE > *1 : Only for AT models *2 : Only for MT models *3 : Only for dual fuel tank models Operation Section 1 10 5.2 Engine Electronic Control Unit (ECU) The figure below is an external view of the engine ECU. For details on the connector terminal layout, refer to "8.2 Connector Terminal Layout". 5.3 EDU The CRS for the TOYOTA LAND CRUISER (200 series) uses two EDUs (No.1 and No.2). Control of the eight injectors is divided into two systems. EDU No.1 controls cylinders 1, 4, 6, and 7, while EDU No.2 controls cylinders 2, 3, 5, and 8. The following page displays a circuit diagram for one system. 1 11 Operation Section 5.4 Sensors (1) Crankshaft Position Sensor The crankshaft position sensor is a Magnetic Pick Up (MPU) type sensor. The crankshaft position sensor is attached to the crankshaft timing gear, and detects NE pulses according to the number of timing gear teeth. There are 34 timing gear teeth plus two missing teeth. When the two missing teeth pass the crankshaft position sensor, Top Dead Center (TDC) is accurately detected due to the pulse change. Operation Section 1 12 (2) Cylinder Recognition Sensor The cylinder recognition sensor is a Magnetic Pick Up (MPU) type sensor. The cylinder recognition sensor is attached to the camshaft timing gear. When the protrusion on the timing gear (G pulsar) passes the sensor, cylinder recognition is performed according to the pulse change. (3) Accelerator Position Sensor (Accelerator Pedal Module) The accelerator position sensor is a Hall element type sensor. Accelerator position is converted to an electrical signal that is output to the engine ECU. 1 13 Operation Section (4) Coolant Temperature Sensor The coolant temperature sensor detects the temperature of the engine coolant. The coolant sensor contains a builtin thermistor that undergoes changes in resistance according to coolant temperature. The change in coolant temperature is detected using the change in the thermistor resistance value. 5.5 Exhaust Gas Recirculation (EGR) Valve The EGR valve is a linear solenoid type valve. The amount of EGR valve lift is changed according to signals from the engine ECU, to control the volume of exhaust gas sent to the intake manifold. Operation Section 1 14 6. FUEL INJECTION CONTROL 6.1 Outline Fuel injection control can be roughly divided into the following four types of control: 1) Fuel injection quantity control, 2) fuel injection timing control, 3) fuel injection rate control, 4) fuel injection pressure control. Basic control content is identical to that contained in the general edition manual. However, the injection pattern is different for the LAND CRUISER (200 series). The following is an explanation of the injection pattern. 6.2 Injection Pattern Fuel injection timing is controlled according to the duration the injector is energized. First, main injection timing is determined, followed by timing determinations for pilot injections 1 and 2.
