ABSTRACT:
A control system for internal combustion engines with externally supplied ignition and having a throttle valve in the air intake tube, a controllable bypass around the throttle valve and a fuel metering system, in which at least at predetermined operating states, a special fuel metering signal is formed in accordance with the control signal for the bypass opening and preferably also in accordance with the rpm. It is thereby possible to establish a supplementary air quantity and a supplementary fuel quantity independently of one another in individual operating ranges; this provides a great deal of freedom and makes it possible to attain quite various possible kinds of regulation, such as idling-rpm regulation, lambda regulation, engine smoothness regulation and fuel consumption regulations. For generating the special fuel metering signal, a performance graph is efficaciously used, by way of which various operating parameters, such as temperature, can be taken into account.
