Title: Electronically controlled fuel injection device
Inventor: KAJITA KAZUO
IPC: F02D41/06
Filed: 1978-07-13
Abstract: PURPOSE: To procure startability of an engine by calculating and controlling the fuel injection amount by use of a signal which is formed by delaying an ignition signal in the engine starting condition.  
     CONSTITUTION: During the cranking in engine starting operation, when the engine revolution rate is lower than a predetermined revolution rate, an AND gate 17 is opened and a delay pulse signal F is fed from a second monostable multivibrator 13 to a frequency divider circuit 3. Because the fuel injection pulse signal calculated by an arithmetic circuit 4 and a multiplication circuit 5 is different from the ignition timing of an ignitor in phase, the signal is not fed out when the battery voltage is lowest, the circuits 4 and 5 operate at sufficient operating voltages, and an injection valve is driven at a sufficient voltage.
