LUBRICATION SYSTEM


  1. CONSTRUCTION


    1. Oil Pump


      1. The oil pump now uses compact, high-efficiency multi-toothed trochoid rotors driven directly by the crank shaft and has a timing chain or belt cover sub-assembly installed. The discharge amount has been optimized, shrinking the rotor diameter and reducing friction.

      2. The relief valve is now internal, and a bypass line to prevent released oil from going directly to the oil pan has been installed, suppressing fluctuations in the oil pan oil level and reducing friction.

      3. FIPG (liquid gasket) with excellent sealing qualities has been adopted for the attachment surfaces of the cylinder block, cylinder head and oil pan to ensure reliability.

      4. The oil pump into the timing chain or belt cover sub-assembly is non-destructive.

    2. Oil Filter


      1. A compact, lightweight oil filter with a built-in relief valve has been adopted.

      2. Serviceability has been improved by positioning the oil pan above the engine.
