Abstract

236,914. Balachowsky, D., and Caire, P. July 1, 1926. Vaporizers, external.-A device for feeding internal-combustion engines with heavy fuels comprises a nest of tubes of copper or nickel, and also packed therewith, through which heavy fuel is passed, air being mixed with the fuel either before or after passing through the tubes which are heated to at least 350‹ C. by exhaust passing around them. In modifications, the exhaust passes through the tubes and the fuel around them. As shown in Fig. 1 mixture from a carburettor E passes through a box A to an outlet F connected to the induction pipe, the box being exhaust-jacketed and traversed by exhaust tubes B. The box and tubes are made of copper or nickel and the box is packed with copper or nickel filings or scrap. Steam, with or without air, may be admitted at H. In a modification, the mixture enters a collecting-chamber connected by a series of copper or nickel tubes packed with copper or nickel to a second collecting- chamber connected to the induction tube, the whole being exhaust-jacketed. In a further modification, an exhaust-jacketed-chamber packed with copper .or nickel and traversed by copper or nickel exhaust pipes is provided at the bottom with inlets for fuel alone and for water, alcohol, or a mixture thereof, the outlet from the chamber being provided with a compressed air nozzle. In the form shown in Fig. 6, fuel from a vessel N, and water, alcohol or a mixture thereof from a vessel L are supplied to an exhaust-jacketed chamber A<1> the upper and lower parts of which are traversed by copper or nickel exhaust tubes B surrounded by copper or nickel. The vapours produced in the lower part of the chamber pass through filtering material M, e.g. perforated copper plates or gauze, and are decomposed in the upper part of the chamber. Air is admitted to the outlet D through a nozzle K. According to the Specification as open to inspection under Sect. 91 (3) (a), the tubes may be made of any catalytic metal or alloy, and the packing may consist of a catalyst or absorbent substance. The tubes may be of various crosssections, e.g. flattened, or may be capillary, in which case the fuel is introduced by means of a pump. The apparatus may comprise a tube through which fuel vapour is passed, the tube containing a mass of catalyst heated electrically or by exhaust tubes. This subject-matter does not appear in the Specification as accepted.
