Beschreibung
Zusammenfassung:	An internal combustion engine with charge stratification and directed airflow is provided. A charge motion control valve (70) is positioned in the upper intake manifold (18) and bifurcated intake ports (41) are utilised in the cylinder head (14) which direct the air flow into one intake port when desired. This provides improved engine performance, emissions, and fuel economy with easier packaging and consequently reduced cost.
