Abstract

Es wird ein Kosten sparendes Verfahren zur Ermittlung der Drehzahl (NT2) eines Turboladers (17) in einer Bi-Turbo- Brennkraftmaschine (1) bereitgestellt, welche - einen Ansaugtrakt (6), welcher mindestens einen einflutigen Abschnitt (10, 19) und einen doppelflutigen Abschnitt mit einem ersten Ansaugast (7) und einem zweiten Ansaugast (8) umfasst, und - zwei Turbolader (14, 17), von denen ein erster Turbolader (14) in dem ersten Ansaugast (7) und ein zweiter Turbolader (17) in dem zweiten Ansaugast (8) angeordnet ist, aufweist wobei das Verfahren dadurch gekennzeichnet ist, dass - eine erste Betriebsgröße der Brennkraftmaschine (1) in dem ersten Ansaugast (7) erfasst wird, - eine zweite Betriebsgröße der Brennkraftmaschine (1) in dem einflutigen Abschnitt (10, 19) erfasst wird, und - die Drehzahl (NT2) des zweiten Turboladers (17) basierend auf der ersten Betriebsgröße und der zweiten Betriebsgröße berechnet wird.
