摘要： A method for the control of secondary air amounts on a motor vehicle with a device (3,4,5,6) for secondary air injection is characterised in that the increase in injected secondary air is controlled with time such as to change dependent on the start conditions of the motor vehicle and the heating progress of the catalyst (8) as determined by measurement or modeling.

摘要： The invention relates to an internal combustion engine (1), especially for use in a motor vehicle, provided with a combustion chamber (4) in which air can be drawn via a throttle valve (11). Fuel can be directly injected into the combustion chamber by an injection valve (9) in a first operating mode during an induction phase or in a second operating mode during a compression phase, and the fuel can be ignited by a spark plug (10). An air/fuel mixture can be fed to the combustion chamber (4) via a tank ventilation assembly (15, 16, 17). The internal combustion engine (1) is controlled and/or regulated by the control device (18) in such a way that, in the second operating mode, a lean air/fuel mixture is drawn into the combustion chamber (4) via the throttle valve (11) and via the tank ventilation assembly (15, 16, 17) and is ignited by fuel which is additionally injected into the combustion chamber (4) and ignited therein.

摘要： The invention relates to a method for identifying phases on a multi-cylinder spark-ignited internal combustion engine, which has an even or odd number of cylinders and which is operated by means of an engine management system. The working cycle of the internal combustion engine extends at least over two revolutions. In the event of an unknown phase position, the internal combustion engine is started with double ignition output under the assumption of a phase position. An intervention in the formation of the mixture with regard to a leaning or an enriching of the mixture is carried out at one or more cylinders of the internal combustion engine. The phase position assumed at the beginning when starting the internal combustion engine is verified or falsified based on the detection and changes of the air ratio μ. In the event of a falsified phase position, an emergency operation of the internal combustion engine with double ignition output is maintained or newly synchronized or resynchronized.
