  1. FUNCTION


    1. Hydraulic Control (Models with DPF Catalyst)


      1. A 2-stage hydraulic system that allows the engine oil pressure to be controlled in accordance with the vehicle driving conditions is used. Therefore, energy loss due to the driving of the oil pump has been reduced and fuel economy has been improved.


        1. High Pressure Operation


          • As oil is not supplied to the back of the sleeve valve, the oil discharge pressure presses the sleeve valve downward and lowers the relief hole position. Therefore, the valve opening pressure becomes high.

        2. Low Pressure Operation


          • As oil is supplied to the back of the sleeve valve, the sleeve valve is pushed upward and the relief hole position is raised. Therefore, the valve opening pressure becomes low.

  2. CONSTRUCTION


    1. Oil Nozzle Sub-assembly


      1. An oil nozzle sub-assembly is provided in the cylinder block sub-assembly for cooling and lubricating the pistons.

    2. Oil Filter


      1. An oil filter with a replaceable element is used. The element uses high-performance filter paper to improve filtration performance. It is also combustible for environmental protection.

      2. This oil filter has a structure which can drain the oil remaining in the oil filter. This prevents oil from spattering when replacing the element and allows the technician to work without touching hot oil.

        Tech Tips


        • The oil in the oil filter can be drained by removing the drain plug and inserting the oil filter drain pipe supplied with the element into the oil filter. For details, refer to the Repair Manual.

        • The engine oil maintenance interval for a model that has an oil filter with a replaceable element is the same as that for the conventional model.
