Controlling the exhaust gas behavior in low consumption lean mode is a great challenge for direct fuel injection. The resulting nitrogen oxide emissions are lower as they leave the engine than with conventional gasoline engines and are lowered further through high exhaust gas recirculation rates: however, they cannot be reduced by the familiar three-way catalytic converter. The new NOx storage catalytic converter required for compliance with the strict exhaust emission laws must be regenerated every minute. To do this, the mode is briefly switched from 'lean stratified' to 'normal homogeneous'. The most difficult task here relates to the engine management system which has to switch back and forth between the two modes instantaneously and unnoticed by the driver. The Motronic MED 7 engine management system - the first series concept of this type -specially developed by Bosch for direct injection gasoline engines is intended for these management tasks. Its task is to control the fuel quantity, throttle valve and ignition angle in such a way that the engine torque remains constant during the switchover. In conjunction with the electronic EGAS throttle valve controller, the MED 7 system represents the decisive basis for the introduction of BDE into series-type production.
