  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 valve rocker arms with built-in needle bearings. This reduces the friction that occurs between the cams and the valve rocker arms when the valves are pushed down, thus improving fuel economy.

    3. A valve lash adjuster assembly, which maintains a constant zero valve clearance through the use of oil pressure and spring force, is used.

    4. The intake camshafts are driven by the crankshaft via the primary timing chain. The exhaust camshafts are each driven by the intake camshaft of their respective bank via a secondary chain.

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