The present invention relates to a semi-active engine mount which is formed in an electronic bypass type. The present invention provides an active engine mount for a vehicle as a system, wherein so as to optimize characteristics of the electronic bypass type, an orifice which is a slender type and a bypass unit are integrated. An entrance of a slender type nozzle is placed in a central portion which receives the most volume pressure of an upper liquid chamber, and is used along with the bypass unit, thereby maximally making better use of a space to maximize loss coefficient characteristics. The active engine mount for a vehicle comprises: an upper body which has a main rubber and an upper liquid chamber; a lower body which is coupled to a lower portion of the upper body; an orifice circular plate dividing the interior of the upper and lower bodies into the upper liquid chamber and a lower liquid chamber inside the upper and lower bodies, and having an orifice through which a fluid flows between the upper and lower liquid chambers; a diaphragm installed below the orifice circular plate inside the upper and lower bodies, and forming the lower liquid chamber; and a semi-active mount which is in contact with the central portion of the diaphragm by a plunger inside the lower body, and operates by an electromagnet. |
