- Balance weight is appropriately provided for the crankshaft and flywheel to reduce vibration.
- [Tightening Torque] - Plastic Region Tightening Bolts (Inside): 35 N·m + 180° - Plastic Region Tightening Bolts (Outside): 60 N·m + 90°
- Three bolts tighten the crankshaft pulley onto the crankshaft to reduce the tightening torque and improve serviceability. Tightening Torque: 115 N·m x3 Reference: Tightening Torque for 1HD-FTE: 430 N·m
- Timing gear and 2 timing chains are used.
- 2-rotor type oil pump is used.
- Oil filter cap made by resin.
- When driving on slope way, the engine oil retains in the turbocharger if this system isn't equipped. On the models with this system, the conventional oil outlet pipe for turbocharger is discontinued and scavenging pump is added to prevents oil from retaining in the turbocharger. The scavenging pump suctions the return oil of turbocharger and sends it to the oil pan. It securing the reliability of the engine.
- Scavenging Pump: Sucks the engine oil in catch tank and discharge it to the oil pan. Oil Catch Tank: Separate the engine oil to air-liquid.
- Scavenging pump is the trochoid gear type oil pump. The scavenging pump (bearing portion etc.) is lubricated by rotating the scavenging pump.
- 2 turbochargers are used for each bank.
- Variable nozzle vane type turbocharger to ensure higher effectiveness in full range. Nozzle vane is driven by the DC motor. Water-cooled type turbocharger
- Depending on the engine speed, angle of vane is changed. [At low engine speed] Vane angle is changed to make narrower exhaust gas passage. Thus, the exhaust gas speed applied to turbine is increased to spin the turbine with higher speed. [At high engine speed] Vane angle is changed to make wider exhaust gas passage.
- This system is controlled by the ECM. 2 turbo motor drivers are used for each turbocharger.
- For all model
- EGR system is used for EUROIV, EUROIII or EURO II model. The EGR passage is provided in the cylinder head. Laminated structure type EGR cooler is used.
- [Features of Fuel System] - Common-rail system is used - 3 plunger type HP4 supply pump - 9-hole type solenoid injector - 2 Common-rails for each bank - Water-cooled type fuel cooler - Air-cooled type fuel cooler at the under floor - Element replacement type fuel filter - Fuel filter warning switch is used to detect filter clogging - Recirculation type fuel heater (-W: STD / Gen: OPT) - [Dual Tank Model Only (-Q, -V, Gen)] Fuel pump is provided in the main fuel tank to transfer the fuel in sub tank to main tank There are 2 return paths to prevent the pressure of the return fuel from increasing. If the pressure of the return fuel increases, the performance of fuel system parts decreases. On the dual fuel tank model, the return tube passes through the sub fuel tank and returns to the main fuel tank. This construction utilizes the heat of the return fuel that has been warmed by the engine to prevent the temperature in the sub fuel tank from decreasing. If the temperature in the sub fuel tank decreases, the fuel viscosity become high and the fuel transfer does not operate normally.
- [Common-rail Pressure] EURO IV Model: 25 ~ 175 MPa Except EURO IV Model: 25 ~ 129 MPa
- 3 plunger type supply pump is used to correspond to the injection volume increase by high displacement and high output engine.
- 9-hole type solenoid injector Small injection hole ( 0.113 mm)
- Element replacement type fuel filter is used.
- The filter cap is installed by the bolt to improve serviceability at the element replacement. Recirculation type fuel heater is used for –W as standard equipment and -_ as optional equipment.
- [Optitron Type Combination Meter] When the fuel filter clogging is detected by fuel filter warning switch, “Fuel Filter Maintenance Reqd” message is displayed on the multi-information display in combination meter. It shows that the fuel filter replacement is required. Note: Master warning light is turned on with the indication of the warning message. [Analog Type Combination Meter] When the fuel filter clogging is detected by fuel filter warning switch, the Fuel System Warning Light is turned on. It shows that the fuel filter replacement is required.
- Fuel filter warning switch is same as KD series engine on HIACE and IMV. Fuel filter clogging system: Vacuum switch Filter element is clogged, suction from supply pump generates higher negative pressure in fuel pipe. Then, switch is turned off.
- Analog Type Combination Meter Only This warning light is for both filter warning and sedimenter warning. Warning condition: - Sedimenter warning: blink - Fuel filter warning: stays on If the both sedimenter and fuel filter warning are detected, the warning light blinks (as sedimenter warning).
- The clogging detection is memorized in EEPROM and the warning message/light is indicated until reset operation is performed. After the fuel filter replacement, perform the reset operation to turn off the warning message/light. Reset operation is same as KD series engine on HIACE and IMV. [Reset Operation] 1. After the fuel filter replacement, turn the engine switch on (IG). (The fuel filter warning switch connector should be disconnected before engine switch on (IG).) 2. Connect the fuel filter warning switch connector within 3 – 60 sec. after engine switch on (IG). 3. 3 sec. after the step2, warning message/light is turned OFF.
- Water-cooled type fuel cooler cools the return fuel from injector.
- Air-cooled type fuel cooler cools the return fuel from engine (injector).
- Fuel pump and jet pump are used to transfer the fuel in the sub tank to main tank. Note: The fuel tank change over system which is used with previous model is discontinued. [Sub Fuel Tank] - Standard equipment for –Q and –V - Optional equipment for -_ - Not equipped for -W
- ECM controls a fuel pump in accordance with the amount of fuel consumption. The fuel pump in the fuel tank operates the jet pump for fuel transfer.
- When the Meter ECU detects the malfunction in the fuel transfer system, the fuel level warning light is blinked. [Malfunction Detection Condition] Fuel of 7.8-liter or more remains in the sub tank when the fuel level of the main tank becomes 20.7-liter. Above condition shows that the fuel transfer operation is not done normally.
- The electrical hydraulic type is used for the front engine mounts to reduce the engine vibration at idling.
- [When the VSV is OFF] Vacuum is not introduced to the engine mount. The fluid passes the No.1 fluid passage only. Mount Characteristic = Hard [When the VSV is ON] Vacuum is introduced to the engine mount and the No.2 fluid passage is opened. The fluid passes the No.1 and No.2 fluid passage. Mount Characteristic = Soft
- When the engine is idling and vehicle is driving at a low speed, the VSV is turned ON (mount = soft) to reduce engine vibration.
- Dash panel penetration installation is adopted a countermeasure for heat. ECM with waterproof connector. Note: This vehicle uses a fluid coupler driven cooling fan. This system does not control heat in the engine compartment as well as electric cooling fans therefore the ECM is in the cab area for temperature control and the connector is in the engine compartment so that the wire harness does not have to route through the dash panel.
