ENGINE UNIT


  1. CONSTRUCTION


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

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

    3. Oil lubrication for the valve rocker arm sub-assemblies are conducted by the oil delivery pipe in the cylinder head cover.

    4. The intake camshaft and exhaust camshaft are driven by the crankshaft via the timing chain.
