ENGINE UNIT


  1. CONSTRUCTION


    1. A plastic case separator is provided between the cylinder block sub-assembly and the intake air surge tank assembly in order to separate the engine oil that is included in the blowby gas.

    2. An inertial impaction system is used in the construction for separating the engine oil in the case separator. Blowby gas that contains engine oil hits the plate, causing the engine oil to adhere to and accumulate on the plate. Then, the oil drips down by way of gravity. Thus, this system efficiently separates the engine oil from the blowby gas. This improves the capture ratio of the engine oil and reduces the amount of engine oil consumption.

    3. The oil separator chambers in the cylinder head cover sub-assemblies have been made compact through the use of a case separator. This contributes to making the entire engine compact.

    4. The case separator draws fresh air from the left and right cylinder head cover sub-assemblies to improve the ventilation inside the engine and improve the lifespan of the engine oil.
