Abstract

Un dispositivo de control aplicado a un sistema que tiene un motor adaptado de modo que el coeficiente de expansión del motor pueda cambiar. El dispositivo de control tiene una sección de obtención de coeficiente de expansión para obtener el coeficiente de expansión y también tiene una sección de estimación de temperatura para estimar, con base en el coeficiente de expansión obtenida por la sección de obtención de coeficiente de expansión, la temperatura del gas de escape descargado del motor o la temperatura del miembro colocado en una ruta para el gas de escape.
