ENGINE UNIT


  1. CONSTRUCTION


    1. Each cylinder of this engine has 2 intake valves and 2 exhaust valves. Intake and exhaust efficiency is increased due to the larger total port areas.

    2. This engine uses No. 1 valve rocker arm sub-assemblies with the built-in needle bearings. This reduces the friction that occurs between the cams and the No. 1 valve rocker arm sub-assemblies that push the valves down, thus improving fuel economy.

    3. Valve lash adjuster assemblies, which maintain a constant zero valve clearance through the use of oil pressure and spring force, are used.

    4. The intake camshafts are driven by the crankshaft via the chain sub-assembly (primary). The exhaust camshafts are each driven by the intake camshaft of their respective bank via a No. 2 chain sub-assembly (secondary).

    5. This engine has the Dual Variable Valve Timing-intelligent (Dual VVT-i) system which controls the intake and exhaust camshafts to provide optimal valve timing in accordance with driving conditions. With this, lower fuel consumption, higher engine performance, and fewer exhaust emissions have been achieved.
