摘要
The mixture control method for a motor vehicle internal combustion engine (1) involves closed circuit regulation of the richness of the exhaust gases when the engine is operating in the stratified combustion mode. The difference between a pre-set medium richness corresponding to a speed range and engine charge is measured against the measured medium richness and the air intake of the engine is then regulated (5) using the motorized throttle butterfly (4). Claims include a control circuit for carrying out the method
