ENGINE UNIT


  1. CONSTRUCTION


    1. An 8 mm (0.315 in.) pitch bush chain is used, reducing weight, improving quietness and reducing friction.

    2. The phase of the valve cam and fuel pump cam is optimized, reducing chain tension. As a result, timing chain weight reduction is achieved.

    3. A check ball type chain tensioner with ratchet mechanism that uses engine oil pressure and spring force is used in the No. 1 chain tensioner assembly and a small tensioner that directly pushes the chain using engine oil pressure and spring force is used in the No. 2 chain tensioner assembly and No. 3 chain tensioner assembly) to constantly maintain the timing chain at the optimal tension, ensuring quietness and reliability.

    4. Resin materials with superior friction reducing efficiency and wear resistance are used on the No. 1 chain vibration damper, No. 2 chain vibration damper and chain tensioner slipper.

    5. The number of teeth of the idle sprocket assembly is optimized and rubber is installed at the base of the teeth, ensuring quietness.
