ENGINE UNIT


  1. CONSTRUCTION


    1. Intake and exhaust efficiency has been increased due to the larger total port areas.

    2. This engine uses valve rocker arm sub-assembly with built-in needle bearings. This reduces the friction that occurs between the cams and the areas on the 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 camshaft and exhaust camshaft are driven by a timing chain.

    5. This engine uses 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.
