Abstract

PURPOSE: To supply air to an engine for automatically preventing the stole of the engine by opening a suction pipe when the revolutions of the engine have come below a set value thereof.
CONSTITUTION: The signal generated by an engine revolution sensor is converted into digital signal S2 by a waveform adjusting circuit 2, a clock oscillator 3 and a counter 4. The signal S2 is converted into that representing the revolutions of the engine by an operating circuit 5, and the latter signal is fed to a comparator 6, which compares with the revolutions those which are stored in a memory 7 and have a possibility of causing stall. When the revolutions of the engine have come below a set value, the signal S2 is generated by an output circuit 2, a solenoid valve 9 is excited to open, the negative measure of a negative-pressure responding valve 12 has reduced to zero, and the valve 12 opens so that air is fed to the engine, bypassing the slot 11 of a suction pipe 10.
