LUBRICATION SYSTEM


  1. OUTLINE


    1. The lubrication circuit is fully pressurized and all oil passes through an oil filter.

    2. The crankshaft drives a trochoid gear type oil pump. The oil pump fits compactly inside the timing chain cover.

    3. The oil strainer is made of plastic to reduce weight.

    4. This engine has an oil return system in which the oil is force-fed to the upper cylinder head sub-assembly and returns to the oil pan through the oil return holes in the cylinder head sub-assembly and cylinder block sub-assembly.

    5. The camshaft timing oil control valve regulates the oil pressure and then supplies oil into each VVT-i Controller (Camshaft Timing Gear Assembly).

    6. The No. 1 oil nozzle sub-assembly is employed in the piston cooling and lubrication.

    7. The oil check valve sub-assembly is used in the rear engine oil seal cooling for the stop and start system.

    8. An oil filter with a replaceable element is used.
