Abstract
PURPOSE: To prevent contamination coverage on plugs in an EFI engine by prohibiting the injection when the device's main swtich is repeated on and off again for a device to determine the amount of injection according to the relation between the engine temperature and requisite fuel injection time at the time of starting.
CONSTITUTION: The relation between the engine temperature TE and injection time signal Ti is stored in a memory 1. When the main switch S is turned on and the terminal voltage exceeds the reference voltage Es, a comparator 9 will give an output and the monomulti 10 yields the pulsation output. Signals from the memory 1 is led in, at the same time, through a resistor 2 and a preset down counter 3 as a signal decreasing by steps, and further forwarded to a flipflop 6 controlling the injection solenoid. Even if the main switch S is turned on again before the preset time, the monomulti 10 will not give any output because the output of comparator 9 is still held in the condition "1".
