Abstract
An electronically-controlled fuel injection system for internal combustion engines is disclosed. Pulse width of a reference pulse generated in accordance with principal engine operating parameters is converted into a binary code and memorized. Oscillation signal having a frequency responsive to other engine operating parameters is counted starting in synchronism with the engine rotation until the count value thereof coincides with the memorized value. During the oscillation signal counting electromagnetically-operable injectors are opened sequentially in the engine suction stroke. The resultant fuel injection amount is dependent on the principal and other engine operating conditions.
