ABSTRACT:
A system for supplying fuel to an internal combustion engine, the fuel supply being dependent on the driving condition of the engine, comprises two types of detectors for detecting engine driving conditions and a memory for generating a signal representative of the fuel injection quantity in response to the engine driving conditions. A time-control circuit generates a pulse having a time duration determined by the output from the memory and a fuel injector injects fuel into the engine in accordance with the pulse of the time-control circuit. The memory comprises two stages, the first stage being a group of logical product circuits the number of which is dependent upon the number of different kinds of values defined as a function by two kinds of data of the engine driving conditions and the second stage being a group of logical summing circuits the number of which is the number of digital bits transmitted to the time-control circuit, in order to simplify the structure of the memory and to economize manufacture.
