ABSTRACT:
A control apparatus for a fuel supply system for mixture-compressing, externally ignited internal combustion engines is proposed, which serves to interrupt the fuel supply to the engine during overrunning. The control apparatus comprises sensors which furnish signals according to the attitude of the throttle valve, as well as the rpm of the internal combustion engine and the temperature of a catalytic converter situated in the exhaust pipe, and further comprises means for the evaluation of these signals as well as for the interruption of the fuel supply to the internal combustion engine and the introduction of supplementary air during overrunning at catalytic converter temperatures above the proper operating temperature for that device.
