ENGINE UNIT


  1. CONSTRUCTION


    1. In pursuit of high-precision valve timings, a chain sub-assembly with a 8 mm (0.315 in.) pitch is used to reduce wear and elongation.

    2. The No. 1 chain tensioner assembly uses a spring and oil pressure to maintain proper chain tension at all times. The No. 1 chain tensioner assembly suppresses noise generated by the chain sub-assembly. Also, a ratchet construction is used to improve quietness during starting and low engine speeds.

    3. A resin with a friction reduction effect and high anti-friction performance is used for the shoes of the chain tensioner slipper and timing chain guide to improve low fuel consumption and reliability.

    4. An aluminum die-cast timing chain cover assembly is used.

    5. The timing chain cover assembly has an integrated construction consisting of an oil filter bracket and engine water pump assembly. Thus, the number of parts has been reduced, resulting in a weight reduction. Also, a service hole cover for the No. 1 chain tensioner assembly is installed to improve maintenance serviceability.

    6. The timing chain cover assembly has a structure which allows the installation of a cam timing oil control solenoid assembly for VVT-iW and VVT-i control.

    7. The reinforced ribs have been optimally placed while the thickness of the timing chain cover assembly has been reduced to achieve weight reduction and quietness.
