Abstract

Para obtener en una unidad de diagnostico (70) para la prueba de hermeticidad en un sistema de tanque (10) de una maquina de combustion interna, un gasto de energia minimo durante las pruebas de diagnostico y simultaneamente impedir la emision de los gases de combustion, se propone de acuerdo con la invencion un mecanismo de entrada en reposo y en estado activo (270, 300, 350) en el cual la unidad de diagnostico (70) despues de la detencion de la maquina de combustion interna se transfiere a un modo de reposo durante un intervalo de tiempo predeterminado, y la unidad de diagnostico (70) despues del transcurso del primer intervalo de tiempo se transfiere a un modo activo y en el modo activo se captan cuando menos los datos de medicion necesarios para realizar el diagnostico, y la unidad de diagnostico (70) posteriormente dentro del periodo de tiempo que dure el diagnostico se vuelve a transferir al modo de reposo y la unidad de diagnostico (70) se desconecta despues del transcurso de la duracion del diagnostico.
