Abstract

CON EL PRESENTE SISTEMA DE AIREACION DE TANQUES, COMPUESTO DE UN TANQUE DE PLASTICO (1), UN FILTRO DECARBON ACTIVO (2), UN APARATO DE MANDO (4), UNA SONDA LAMBDA (521), UNA VALVULA DE AIREACION DE TANQUE (3) Y UN SENSOR DE CORRIENTE (7), SE RECONOCEN RAPIDAMENTE LOS ERRORES EN LAS CONDUCCIONES DE CONEXION Y EN LA VALVULA DE AIREACION. PARA RECONOCIMIENTO DE ERRORES, ESTAN PREVISTOS MEDIOS QUE INVESTIGAN LAS SEÑALES QUE LLEGAN DESDE LA SONDA LAMBDA Y DEL SENSOR DE CORRIENTE CON LAS SEÑALES QUE SALEN PARA LA VALVULA DE AIRREACION DEL TANQUE. AL RECONOCER EL ERROR, SE ALMACENA LA SEÑAL ERRONEA. COMO SENSOR DE CORRIENTE SE UTILIZA PRINCIPALMENTE UN CONDUCTOR FRIO CERAMICO.
