ENGINE UNIT


  1. CONSTRUCTION


    1. A lightweight and high-strength aluminum die-cast stiffening crankcase assembly is used. This assembly is integrated with the cylinder block sub-assembly, thus improving the rigidity of the join with the transaxle, and reducing vibration and noise transmitted to the interior of the vehicle cabin.

    2. Oil drain passages are provided in the stiffening crankcase assembly. This prevents the crankshaft from churning the engine oil, reducing rotational resistance.

    3. A passage for introducing blowby gas into the oil separator is integrated into the stiffening crankcase assembly. Additionally, the passage uses a labyrinth structure to separate oil mist from the blowby gas, reducing oil consumption.

    4. The high pressure oil passage, rear oil seal retainer, oil filter bracket and rear end plate are integrated with the stiffening crankcase assembly, thus reducing the weight of the engine and making it compact.
