Abstract
An internal combustion engine with charge stratification and tumble motion is provided. A tumble control valve is located in the intake pore upstream of the fuel injector creating a high velocity airflow. Fuel injected by the fuel injector is entrained into the high velocity airflow produced by the tumble control valve thereby establishing an airflow within the cylinder having fuel rich and fuel lean regions. The airflow in the cylinder circulates about an axis substantially perpendicular to the axis of operation of the piston.
