ENGINE UNIT


  1. CONSTRUCTION


    1. In pursuit of high-precision valve timings, a roller chain (chain sub-assembly) with a 9.525 mm (0.375 in.) pitch is used to reduce wear and elongation.

    2. A timing chain guide is used between the camshaft timing gear assembly and camshaft timing exhaust gear assembly to ensure quietness and reliability by suppressing vibrations in the chain sub-assembly between camshafts.

    3. 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 timing chain. Also, a ratchet construction is used to improve quietness during starting and low engine speeds.

    4. A resin with a friction reduction effect and high anti-friction performance is used for the shoes of the chain tensioner slipper, No. 1 chain vibration damper and timing chain guide to improve low fuel consumption and to ensure reliability.
