Aerodynamic Computation of Air Fuel Ratios 800506

The rate of fuel flow for maintaining a constant AF ratio is derived from the turn angle of a spring-restrained air-screw type rotor placed in the engine air flow. Operationally required A/F changes are imprinted on the flow with vortices generated with small vanes, individually deflected in relation to engine load or -temperature variations. Air velocity and vorticity contain the data for A/F control which are integrated with the multi-bladed rotor.
Vane vortex theory and air flow test approaches and results are presented, a prototype control device defined and analysed, alternate versions shown and factors affecting engine compatibility discussed.
