An ultrasonic fuel atomizer which is inserted between a standard carburetor and intake manifold of an internal combustion engine to cause a more uniform mixture of fuel and air to be attained, thereby promoting fuel economy and increasing the efficiency of combustion. The apparatus driver a vibrating plate assembly which is excited by a driven such as a piezo electrical crystal. Within the housing of the apparatus there is formed a cavity through which fuel and air must travel along a prescribed path which causes large droplets of fuel to impinge upon the vibrating plate, thereby drastically reducing the droplet size of the fuel.

In combination with an internal combustion engine having an intake manifold flow connected to a carburetor, a post carburetor atomizer apparatus interposed between said carburetor and manifold; said atomizer apparatus comprising a housing having an inlet and an outlet, an exciter, an atomizer plate assembly; means including circuitry connected to said exciter for causing excitation thereof; said housing comprising upper and lower cavity forming members having said upper and lower separators attached thereto; said separators having adjacent sharp edge portions which are spaced from said plate assembly when said upper and lower portions of said housing are mated so that said atomizer plate assembly is enclosed within said housing such that an annulus is formed about said plate assembly to cause large droplets of fuel to be forced to impinge upon said plate assembly and the droplets subsequently atomized by the vibrating action thereof; said plate assembly being apertured and provided with opposed faces; a load bolt means having a shoulder formed thereon for engagement with one said face, a locking ring, a load ring, said exciter being compressed between said locking ring and load ring, a marginal circumferentially extending annular area of said plate assembly being compressed between said load ring and said load bolt means; an annular area formed on one face of said plate assembly, the last said area being smaller in diameter with respect to the annular area contacted by said load ring, each said annular area being concentrically arranged respective to one another and placed in compression by said load bolt means and said load ring; whereby, said exciter imparts vibration into said locking and load rings to thereby compress the opposed faces of the plate assembly so that the plate assembly vibrates in a flexural mode.
