ENGINE UNIT


  1. CONSTRUCTION


    1. A valve lash adjuster assembly is used in which valve clearance, which changes due to thermal expansion and wear, is always adjusted to zero by oil pressure. Also, a ceramic check ball is used to improve responsiveness.

    2. Both the engine oil that is supplied by the cylinder head and the built-in spring actuate the valve lash adjuster assembly. The oil pressure and the spring force that act on the plunger push the No. 1 valve rocker arm sub-assembly against the cam, in order to adjust the clearance between the valve stem and the No. 1 valve rocker arm. This prevents the generation of noise during the opening and closing of the valves. As a result, engine noise is reduced.
