ENGINE UNIT


  1. CONSTRUCTION


    1. Each cylinder of this engine has 2 intake valves and 2 exhaust valves. Intake and exhaust efficiency is increased due to the larger total port areas.

    2. This engine uses valve rocker arm sub-assemblies with built-in needle bearings. This reduces the friction that occurs between the cams and the areas (valve rocker arm sub-assembly) that push the valves down, thus improving fuel economy.

    3. A valve lash adjuster assembly, which maintains a constant 0 valve clearance through the use of oil pressure and spring force, is used.

    4. The No. 2 camshaft is driven by a chain sub-assembly (timing chain), while the camshaft (intake camshaft) is driven by a gear on the No. 2 camshaft (exhaust camshaft).

    5. A supply pump is driven by the No. 2 camshaft (exhaust camshaft) to achieve a lightweight and compact design.

    6. A vacuum pump assembly is driven by camshaft to achieve a lightweight and compact design.
