Abstract

A method and device for starting an internal combustion engine in a manner which reduces the emissions occurring during starting. The method and device involving setting the throttle valve in an intake duct, accelerating the engine via a crank shaft starter alternator to a desired rotational speed, determining the suction-pipe pressure in the intake duct downstream of the throttle valve, and enabling fuel injection when the suction-pipe pressure undershoots a predetermined threshold value.
