Abstract

DISPOSICION DEL SENSOR DE FLUJO DE AIRE MASICO QUE POSEE UN MARGEN DINAMICO AUMENTADO, EL CUAL TIENE UN SENSOR DE FLUJO DE AIRE MASICO MONTADO FIJAMENTE SOBRE UN SOPORTE DE SENSOR QUE ESTA CONECTADO A LA ZONA DE BAJA PRESION DE UN VENTURI DE AGUAS ABAJO. EL SOPORTE DEL SENSOR TIENE UN CONDUCTO DE FLUJO DE AIRE DE AISLAMIENTO, EN EL QUE ES RECIBIDA LA CABEZA SENSORA DEL SENSOR DE FLUJO DE AIRE MASICO. EL CONDUCTO DE FLUJO DE AIRE DEL SOPORTE DE SENSOR ESTA DISPUESTO EN EL ALOJAMIENTO DEL FILTRO DE AIRE DE UN SISTEMA DE ADMISION DE AIRE DE UN MOTOR DE COMBUSTION INTERNA. EL CONDUCTO DE FLUJO DE AIRE ESTA SITUADO EN UNA ZONA DE FLUJO BAJO DEL ALOJAMIENTO DE FILTRO DE AIRE Y TIENE SU EXTREMO DE SALIDA CONECTADO A LA ZONA DE BAJA PRESION DEL VENTURI SITUADO AGUAS ABAJO DEL ALOJAMIENTO DEL FILTRO DE AIRE. EL VENTURI PUEDE ESTAR CONECTADO DIRECTAMENTE A LA LUMBRERA DE SALIDA DEL ALOJAMIENTO DEL FILTRO DE AIRE, O PUEDE ESTAR SITUADO MAS AGUAS ABAJO.
