  • Publication number: 20160116063
    Abstract: An apparatus for reducing a blow-by gas for a vehicle includes an electromagnet disposed in a cylinder block of an engine and producing a magnetic field with respect to a piston when an electric current is applied thereto. An oil ring is inserted into an outer diameter of the piston to be expandable in an outer diameter direction of the piston by an absorption force of the electromagnet. A controller is controlled by an ECU and applies the electric current to the electromagnet.
