Abstract

Sistema de turbohélice mejorado, comprendiendo el sistema - un motor (E) de combustión interna que tiene un colector (Ex) de escape y una línea (IL) de escape conectada a y adyacente con el colector de escape, - un único sistema (ATS) de purificación de gas de escape dispuesto en dicha línea (IL) de escape, - una turbina (PT) de potencia, dispuesta en la línea (IL) de escape aguas abajo de dicho único sistema (ATS) de purificación, en el que la turbina (PT) de potencia tiene una geometría variable, controlada por medios (ECU) de procesamiento, para aumentar una contrapresión promedio en la línea (IL) de escape y caracterizado porque dichos medios (ECU) de procesamiento están adaptados para controlar una sección de efusión de la turbina (PT) de potencia como una función de la temperatura del gas de escape para hacer el proceso de calentamiento del sistema (ATS) de purificación más rápido.
