ABSTRACT:
A fuel-air proportioning and mixing system for internal combustion engines is disclosed comprising a variable orifice for measuring the volume of air and a motor driven variable volume displacement pump for measuring and atomizing fuel. Changes in size of the variable orifice in response to variations of air volume furnishes energy to modulate the fuel supply to predetermined ratios with continuous correction for air temperature, humidity, and barometric pressure. Electric motor also provides energy to atomize the fuel and mix it uniformly with air passing to engine intake manifold. The fuel-air ratio is controlled from the most economical to the most powerful in response to engine output load.
A variation of the device to accommodate stratified charge engines provides two air fuel ratios -- an ideal mixture for ignition, and a lean mixture automatically variable with torque requirements for the main combustion charge.
Other functions provided include automatic enrichment of mixture for cold starting, controlled deceleration of engine speed to prevent stalling, automatic enrichment of mixture if idle speed declines below a predetermined setting, curtailment of fuel supply while decelerating or coasting above a predetermined engine speed, and a complete cut-off of fuel supply with ignition to prevent dieseling. Since there is no float chamber, percolation and vapor lock are eliminated.
