  6. Engine Overall • Features Air Intake Control System Stepless Controlled Double Electric Cooling Fan

  7. Engine Overall • Specification

  8. Engine Proper • Cylinder Head • Camshaft housing to simply the cylinder head structure • Camshaft bearing cap for IN and EX is one piece Cylinder Head Cover Cylinder Head Cover Gasket Camshaft Bearing Cap Camshaft Housing Cylinder Head Cylinder Head Gasket For IN and EX is one piece

  9. 1 2 3 4 5 8 6 7 Service Point (Engine Proper) • Cylinder Head • Camshaft and camshaft housing installation Step1 : Temporary tighten (Torque: 10N･m [102kgf･cm]) : Tightening order X LH Bank

  10. 6 3 9 12 7 4 1 10 11 2 5 8 Service Point (Engine Proper) • Cylinder Head • Camshaft and camshaft housing installation Step2 : Tighten (Torque: 28N･m [286kgf･cm]) : Tightening order X LH Bank

  11. 1 2 3 4 5 8 6 7 Service Point (Engine Proper) • Cylinder Head • Camshaft and camshaft housing installation Step3 : Tighten (Torque: 16N･m [163kgf･cm]) : Tightening order X LH Bank

  12. Valve Mechanism • Hydraulic Lash Adjuster • Maintaining a constant zero valve clearance through use of oil pressure and spring force Plunger Low Pressure Chamber Zero Valve Clearance Oil Passage Check Ball Check Ball Spring High Pressure Chamber Plunger Spring Oil Passage

  13. Valve Mechanism • Idle Sprocket • The rubber is used to reduce chain noise Rubber Idle Sprocket

  14. Service Point (Valve Mechanism) • Installation of Timing Chain • When the idle sprocket is reused, align the chain plate with the mark where the plate had been in order to tighten the chain between the banks Idle Sprocket (Reuse) Mark

  15. Lubrication System • Oil Filter • Element replacement type oil filter Oil Filter Element Oil Pan No.1 Oil Filter Cap Front Oil Filter Drain Bolt

  16. Service Point (Lubrication System) • Oil Filter • Replace oil filter • Removal Remove filter element Valve Oil Flow O-ring Drain Pipe Drain Pipe Hose Drain Bolt 2. Remove drain bolt, and insert drain pipe to drain oil 1. Connect a hose to drain pipe

  17. Service Point (Lubrication System) • Oil Filter • Replace engine oil and oil filter • Removal SST: 09228-06501 O-ring 3. Remove drain pipe and O-ring 4. Remove oil filter cap

  18. Service Point (Lubrication System) • Oil Filter • Replace engine oil and oil filter • Removal / Installation Install filter element New O-ring New 5. Remove filter element and O-ring from filter cap 1. Set new filter element and O-ring to filter cap

  19. O-ring(new) Drain Bolt Service Point (Lubrication System) • Oil Filter • Replace engine oil and oil filter • Installation SST: 09228-06501 2. Install filter cap using SST 3. Set the new O-ring and install drain plug

  20. Service Point (Lubrication System) • Oil Filter • Replace engine oil and oil filter • Installation No Leakage 4. Refill engine oil 5. Run the engine and check oil leakage

  21. Intake and Exhaust System • Intake Air Chamber • Rotary solenoid type ACIS valve is adopted • ACIS valve is unified by laser-welding Plastic Laser-welding Rotary Solenoid Type ACIS Valve

  22. Reference (Intake and Exhaust System) • ACIS Valve • Rotary solenoid type ACIS valve is used Stator Valve Shaft Magnet Rotary Solenoid type Motor ACIS Valve

  23. Charging System • Alternator Pulley • One-way clutch realizes a low tension V-ribbed belt One-way Clutch Alternator Shaft Bearing Spring Alternator Pulley Alternator

  24. Service Point (Charging System) • Alternator Pulley • Using a SST, when remove or install the alternator pulley SST 09820-63020 (2 parts) Remove Shaft Pulley SST

  25. Service Point (Charging System) • Alternator Pulley • Alternator pulley cap is non-reusable part Alternator Pulley Cap (Non-reusable Part)

  26. Engine Control System • Dual VVT-i (Variable Valve Timing – intelligent) • VVT-i is adopted for intake and exhaust camshafts Retard Intake Advance Retard Lock Pin Advance Vane Exhaust Lock Pin LH Bank

  27. - Effect - • Stable combustion for fuel economy Engine Control System • Dual VVT-i • Operation At Idle, Light Load, Low Temp. and Starting TDC Reduce blow back to the intake side Operation Range Engine Load BDC Engine Speed

  28. - Effect - • Improved emission control • Better fuel economy Engine Control System • Dual VVT-i • Operation At Medium Load Increase internal EGR, Eliminate pumping loss TDC Operation Range Engine Load BDC Engine Speed

  29. - Effect - • Improved torque/output Engine Control System • Dual VVT-i • Operation At Low/Middle speedHeavy Load TDC Operation Range Using the combustion pressure completely Volumetric efficiency improvement Engine Load BDC Engine Speed

  30. - Effect - • Improved output Engine Control System • Dual VVT-i • Operation At High speedHeavy Load TDC Operation Range volumetric efficiency improvement Reduce pumping loss Engine Load BDC Engine Speed
