Zusammenfassung:	An integration of the exhaust manifold into the cylinder head, initially for turbo application, is proposed, and an associated cooling concept is provided. This serves to achieve significant improvements in characteristic features whilst at the same time affording significantly reduced system costs. The advantages of this application are demonstrated taking a four-cylinder petrol engine constructed with direct fuel injection and turbo-charging as an example. Particularly worth emphasizing are the reduced fuel consumption in the ranges at or close to full load, reduced CO2 emissions in the European Driving Cycle, more rapid catalytic converter start-up, and improved engine warm-up and heating of the vehicle interior, together with the significant reduction in complexity through elimination of the conventional exhaust manifold and the associated significant weight and cost reductions.
