Abstract
A device is disclosed which, when used in conjunction with a conventional carburetor metering device of an internal combustion engine, allows formation of a mixture of fuel vapor and air which burns more efficiently and yields less harmful combustion by-products than conventional carburetor systems. Incoming air to the engine is substantially completely saturated with fuel vapors by passing the air through a controlled volume of liquid fuel heated to a predetermined temperature, thereby allowing the air stream to become substantially saturated with fuel vapors. The air-fuel vapor mixture is further leaned downstream by the addition of fresh air, and the leaner, but more uniformly and controllably saturated air-fuel mixture then is introduced into the engine.
Claims12
A carburetor system for a liquid fuel internal combustion engine cooled by a circulating liquid coolant, said system comprising:
- saturation chamber means having a supply of said liquid fuel contained therein;
- air intake means fluidly connected to said saturation chamber means and being operable to direct a supply of air through said liquid fuel contained in said saturation chamber means so as to create a fuel and air vapor mixture for delivery to said internal combustion engine for combustion purposes;
- heat exchange means operably connected to said saturation chamber means and serving to heat said liquid fuel contained in said saturation chamber means so as to compensate for heat loss during a vaporization of said liquid fuel contained in said saturation chamber means;
- and
- storage chamber means for receiving and storing said fuel and air vapor mixture prior to a delivery of said vapor mixture through a vapor conveying means to said internal combustion engine for combustion purposes, said storage chamber means having a supply of said liquid fuel contained therein, said liquid in said storage chamber means being in fluid communication with said liquid fuel contained in said saturation chamber means by means of an orifice means connecting said saturation chamber means and said storage chamber means, said orifice means being positioned below a mimimum level of said liquid fuel contained in said saturation chamber means and said storage chamber means, whereby a substantially constant level of said liquid fuel is maintained between said saturation chamber means and said storage chamber means, said delivery of said vapor mixture to said storage chamber means from said saturation chamber means being effected by a conduit means fluidly connecting said saturation chamber means and said storage chamber means, said conduit means being located above a maximum level of said liquid fuel contained in said saturation chamber means and said storage chamber means.
The carburetor system of 2 wherein said heat exchange means includes a coil immersed directly in said liquid fuel in said saturation chamber means.
