    摘要: In an electromagnetic fuel injection valve, a valve housing includes: a cylinder-shaped valve seat member having a valve seat in its front end portion; a magnetic cylindrical body coaxially connected to a rear end portion of the valve seat member; a nonmagnetic cylindrical body coaxially and liquid-tightly welded to a rear end of the magnetic cylindrical body; and a hollow cylindrical stationary core coaxially and liquid-tightly welded to a rear end of the nonmagnetic cylindrical body. A valve assembly is housed in the valve housing and includes: a valve body capable of being seated on the valve seat; and a movable core connected to a rear end of the valve body and opposed to a front end of the stationary core. The valve body and the valve seat member are respectively made of different martensitic stainless steels so that a hardness of the valve body is higher than that of the valve seat member. Accordingly, it is possible to provide an electromagnetic fuel injection valve for alcohol fuel which is capable of preventing the adhesive wear from occurring in the seat portion while a valve body and a valve seat member made of martensitic stainless steel are used.

    摘要: A transformer is provided with first and second windings that constitute a primary winding, third and fourth windings that constitute a secondary winding, and a magnetic core on which the first through fourth windings are wound. A first distance in a radial direction of a wire between the first winding and the third winding, a second distance in the radial direction of the wire between the first winding and the fourth winding, a third distance in the radial direction of the wire between the second winding and the third winding, and a fourth distance in the radial direction of the wire between the second winding and the fourth winding are substantially equal in the same turn.
