Abstract
SE DESCRIBE UN PROCESO PARA VERIFICAR LA CAPACIDAD DE CONTROL DE LA VALVULA DE VENTILACION DE UN TANQUE A TRAVES DEL CUAL SE SUMINISTRA AIRE SUPLEMENTARIO LLEVANDO VAPORES DE COMBUSTIBLE, A LA ZONA DE ENTRADA DE UN MOTOR DE COMBUSTION INTERNA. ESTE PROCESO SE REALIZA AL MEDIR EN LA ZONA DE VALVULA DE VENTILACION DEL TANQUE, PARAMETROS QUE CAMBIAN CUANDO EXISTE UN FLUJO A TRAVES DE LA VALVULA. ESTO SE HACE PRINCIPALMENTE AL COMPARAR LAS DIFERENCIAS ENTRE LOS VALORES DE ESTOS PARAMETROS ANTES Y DESPUES DE DAR UNA ORDEN A LA VALVULA. LA VERIFICACION PUEDE HACERSE TAMBIEN DEPENDIENDO DE LA PRESION EN LA ZONA DE ENTRADA, COMO SEA NECESARIO, POR EJEMPLO CUANDO SEA REQUERIDO POR LA SENSIBILIDAD DEL SENSOR UTILIZADO.
