Abstract

La presente invención se refiere a mejoras en un carburador con realimentación y medición de combustible, la mejora está caracterizada por pasajes de inducción con una válvula de garganta y un venturi llevados en los mismos para crear la primera presión reducida en respuesta al flujo de aire a través de los mismos, los venturi variables están conectados operativamente a las válvulas de la garganta de manera que la posición de los venturi variables se controlan de acuerdo con la posición de la válvula a la garganta, la primera presión se emplea en combinación en una segunda presión relativamente alta para ocasionar el flujo del combustible medido a los pasos de inducción y componentes adicionales que responden a indicaciones de operaciones del motor para modificar a veces la magnitud efectiva de la primera presión en respuesta a las indicaciones de operación de motor con el fin de modificar correspondientemente por ello el efecto de la primera presión sobre la proporción de flujo de combustible medidor en cualquier momento refleje las indicaciones de operación de motor.The present invention relates to improvements to a carburettor with fuel feedback and metering, the improvement being characterized by induction passages with a throat valve and a venturi carried therein to create the first reduced pressure in response to air flow to Through them, the variable venturi are operatively connected to the throat valves so that the position of the variable venturi is controlled according to the position of the valve to the throat, the first pressure is used in combination in a second Relatively high pressure to cause measured fuel flow to induction passages and additional components that respond to engine operating prompts to sometimes modify the effective magnitude of the first pressure in response to engine operating prompts in order to accordingly modify the effect of the first pressure on the flow rate of Fuel gauge at any time reflect engine operating indications.
