Abstract
In internal combustion engines with external ignition the fuel metering is often interrupted during overrun operation for the purpose of saving fuel. It is proposed to inhibit this blocking of the fuel supply in those cases where the danger of slipperiness because of ice or snow exists. This danger is addressed by means of the method of measuring and evaluation of the intake air temperature and/or the temperature in the vicinity of the motor vehicle. Besides the possibility of realizing the invention from the block switch diagram, it is also pointed out that the electronic control device in accordance with the present invention can also be implemented relatively easily within the confines of a computerized control of the fuel metering.
