ABSTRACT:
Various engine operating conditions are detected by a number of strategically located sensors which convert physically measurable quantities into proportional electrical signals. Such signals are firstly converted into analog signals representative of rectilinearly approximated relation between the input measurable quantities and the amount of fuel necessary for any given engine cycle and secondly converted into a series of command pulses by an exponential converter so that the width of the pulse closely indicates the ideal curvilinear relation between the input quantities and the required fuel quantity.
