Abstract

Un corte de combustible durante la desaceleración se ejecuta en el punto de tiempo t1. Una cantidad (rOS) de almacenamiento de oxígeno que incrementa con este corte de combustible se estima con base en una relación de combustible- aire de escape y una cantidad de aire de admisión. Cuando la cantidad (rOS) de almacenamiento de oxígeno alcanza un valor de umbral (en el punto de tiempo t2), una relación (tCR) de compresión objetivo se corrige para volverse menor que una relación (tCR) de compresión objetivo básica. Aunque se ejecuta una •recuperación de combustible en el punto de tiempo t4, una temperatura de combustión se reduce debido a la reducción de la relación de compresión mecánica, de modo que se suprime una producción de NOx en una cámara de combustión. Por consiguiente, se suprime el empeoramiento del NOx incluso si la cantidad (rOS) de almacenamiento de oxígeno del catalizador (4) de purificación de emisiones de escape es excesiva.
