ABSTRACT:
An improved mechanical air-fuel blending system for use with internal combustion engines, in which a highly compressed fuel such as Liquified Petroleum (LP), is throttled at its storage pressure across a single fuel valve before entering a fuel flow divider which allows the main portion of the discharged LP to flow directly into the air stream before passing to the internal combustion engine. A small portion of the discharged fuel, termed the control fuel, is separated within a fuel flow divider and is diverted across one or more heat exchangers, where it transfers heat to and from the incoming air charge which brings the temperature of the control fuel to that of the incoming air, before entering the air stream at the venturi across one or more orifices. The control fuel pressure within the heat exchanger is compared with the free air pressure entering the system, across a light diaphragm to control the positioning of a fuel valve.
