Abstract

La relación de compresión objetivo se reduce a una relación de compresión mínima mediante un mecanismo (2) de relación de compresión variable, cuando cierto nivel del componente de combustible evaporado se acumula dentro de un recipiente (42) de un dispositivo (40) de procesamiento del combustible evaporado. En este estado se lleva a cabo la purga. La eficiencia térmica se reduce al reducir la relación de compresión. La cantidad del aire de admisión y la cantidad de combustible las cuales son necesarias para el momento de torsión deseado se incrementan. Con esto, aun cuando la cantidad de purga sea la misma, la influencia sobre el coeficiente de corrección de retroalimentación de la relación de aire-combustible se vuelve relativamente pequeña. Por consiguiente, la cantidad de purga posible se incrementa. Por ejemplo, en una región en la cual el coeficiente de corrección de retroalimentación de la relación de aire-combustible es mayor que un valor de límite inferior y el ancho del impulso de inyección de combustible es mayor que un valor mínimo, cuando el grado de apertura de la válvula de control de la purga se ajusta al máximo. En esta presente invención, es posible llevar a cabo la mayor parte de la purga sin provocar desestabilización del control de la relación de aire-combustible, y así sucesivamente.
