ABSTRACT:
The invention relates to a mixture control system which provides the possibility of interrupting fuel during overrun operation. The mixture control system includes apparatus for controllably reducing fuel metering at the start of overrun operation and/or controllably resuming the metering of fuel after the end of overrun operation with the controllable reduction and/or resumption taking place via a corresponding control via the integrator component of the mixture control in dependence upon the composition of the exhaust gas. A very advantageous system with respect to complexity and computation time is provided by the cooperative relationship between lambda control and mixture control.
