LUBRICATION SYSTEM DETAILS

  1. CONSTRUCTION

    1. Oil Pump Assembly

      1. A variable oil discharge volume trochoid gear type oil pump assembly is used.

      2. In the low- and high-speed ranges, the oil pump provides the oil pressure that is necessary for operating the VALVEMATIC, Dual Variable Valve Timing-intelligent (Dual VVT-i), and lubrication system. In the medium-speed range, the surplus oil pressure has been reduced in order to reduce friction.

    2. No. 1 Sub-assembly Oil Nozzle

      1. No. 1 sub-assembly oil nozzle has been provided in the cylinder block for cooling and lubricating the piston.

      2. No. 1 sub-assembly oil nozzle contains a check ball to prevent oil from being fed when the oil pressure is low. This prevents the overall oil pressure in the engine from dropping.
