Abstract

Ein Verfahren, um ein verbrennungsgeschütztes Starten eines Motors zu ermöglichen, umfasst ein Einstellen eines Drosselventils, um einen Luftmassenstrom zu einem Motor eines Fahrzeugs bereitzustellen, der ausreicht, um ein Startdrehmoment zu schaffen. Kraftstoff, der ausreicht, um ein Startdrehmoment zu schaffen, wird während eines Ansaugtaktes eines Zylinders in den Zylinder des Motors eingespritzt. Eine Zündkerze des Zylinders wird gesperrt. Ein Einlassventil und ein Auslassventil des Zylinders werden gesperrt. Der Motor wird abgeschaltet. Ein Verfahren zum Einschalten des Motors umfasst das Freigeben der Zündkerze. Ein Kolben des Zylinders wird zwischen einer OT-Stellung eines Verdichtungstaktes und einer UT-Stellung eines Arbeitstaktes oder zwischen einer OT-Stellung eines Ausstoßtaktes und einer UT-Stellung eines Ansaugtaktes positioniert. Eine Kraftstoff/Luft-Ladung, die ausreicht, um ein Startdrehmoment zu schaffen, wird in dem Zylinder gezündet. Das Einlassventil und das Auslassventil werden zugeschaltet.
