ABSTRACT:
A device is proposed for determining a fuel metering signal for an internal combustion engine comprising a tachometer, a load detector, as well as a storage element and a summing member. The load signal is preferably selected at certain times and then stored temporarily, wherafter the load signal is optionally corrected, multiplied with a time interval, and the sum total of the multiplication results represent a value with respect to the metering signal. Preferably, the signals are processed in a digital fashion, and the load signal is corrected after having been digitized. This is done because for example, in case of a hot-wire air flowmeter, there is no linearity between air flow (air mass flow) and the output signal of the air flowmeter.
