Abstract

Die Erfindung betrifft ein Verfahren zum Starten eines Ottomotors, insbesondere eines Kraftfahrzeuges, wobei zum Sicherstellen eines Hochlaufens des Ottomotors das Kraftstoff-Luft-Gemisch in der Startphase angefettet wird, wobei sich Kraftstoff als Wandfilm in einem Saugrohr ablagert. Hierbei wird während einer Startphase und einer Nachstartphase ein Saugrohrdruck derart gesteuert, daß ein spontanes Abdampfen des Wandfilms vermieden ist.The invention relates to a method for starting a gasoline engine, in particular a motor vehicle, wherein to ensure a run-up of the gasoline engine, the fuel-air mixture is enriched in the startup phase, wherein fuel deposits as a wall film in a suction pipe. In this case, an intake manifold pressure is controlled during a starting phase and a Nachstartphase such that a spontaneous evaporation of the wall film is avoided.
