Abstract

An electrically heated screen arrangement operated from a vehicle battery and automatically controlled to heat the fuel mixture. The fuel mixture provided by the carburetor of the vehicle is drawn through the present system which comprises an outlet conduit from the carburetor delivering fuel mixture through a housing which is closed by a special screen that is electrically heated to the proper temperature and then through a passageway and a cooling device comprising a screen in relationship together with a ceramic filter in a housing. The temperature of the screen is sensed and monitored. Several screens and coolers may be mounted in series.

Claims

1. In a fuel mixture system for an internal combustion engine having a fuel mixture inlet from a carburetor and a fuel mixture outlet back to the intake of an internal combustion engine:

means for supporting a foraminous member to receive the fuel mixture therethrough comprising a support element having a three dimensional support spacing frame,

opposed spaced foraminous members such as a screen supported on opposite sides of said support spacing frame and between said fuel inlet and said fuel outlet for electrical energization to heat the fuel mixture,

electrical means for energizing said foraminous members,

control means for controlling the temperature of said foraminous members,

a three-dimensional housing connecting the fuel mixture inlet to said support element,

means attaching said housing with said outlet,

a cooling unit in communication with said foraminous members,

and there being a plurality of said support elements and cooling units arranged in communication in series.

2. The device claimed in claim 1 wherein said foraminous member is a screen.

3. The device claimed in claim 1 wherein there is an insulator separator on each side of said foraminous member.

4. The device in claim 1 wherein said cooling unit comprises a cooling screen and a filter made from ceramic, plastic and the like.

5. The device in claim 1 wherein there are insulators on opposite sides of said foraminous members and electrical wiring to each foraminous members, said insulators each having an opening therein for the passage of fuel mixture.

6. The device in claim 3 wherein each insulator is flat and each housing has a corresponding flat portion to receive a respective insulator thereagainst.

7. The device in claim 6 wherein each foraminous member is a screen and each screen has an electrical contact and a positive and a negative electric wire leading thereto, and a temperature sensing means on at least one of said screens.

8. The device in claim 7 wherein there is a carburetor screen for the carburetor, support means for said screen, electrical means for energizing said screen and a sensing means for sensing temperature.

9. The device in claim 1 wherein each screen element comprises at least two screen frames having a screen on each side thereof.

10. The device in claim 9 wherein there are insulators on said frames on opposite sides of said foraminous members.
