Abstract

Sistema de alimentación de combustible para motores de cuatro tiempos. Especialmente aplicable a motores de motocicletas consiste en establecer en el conducto principal al que llega el aire procedente del filtro (FA), cuyo caudal está controlado por una válvula de mariposa de gases o principal (1), una válvula de mariposa secundaria (2) que mantienen cada operación de funcionamiento, ya sea en régimen estacionario o transitorio, la apertura adecuada para producir la pérdida de carga que sumada al efecto venturi generado en la sección del conducto aguas abajo de la citada mariposa secundaria (2) y la pérdida de carga del filtro de aire (FA), originando la succión apropiada en la salida (3) de combustible emulsionado que se mezcla con la corriente de aire, combustible que proviene de una cuba (4) de nivel constante, comunicada con la atmósfera, de manera que la succión en la salida (3) produce un flujo a través y controlado por el surtidor principal (5), que emulsionado con aire proveniente del tubo (9), dotado de taladros transversales, descarga en el conducto central del sistema (11) por la salida (3).
