Title:
REVOLUTION NUMBER LIMITOR FOR CONTROLLER OF QUANTITY OF MIXTURE
Document Type and Number:
Japanese Patent JPS53146035
Kind Code:
A
Abstract:
A signal generator for use with a fuel supply system which incorporates a fuel shut-off mechanism. The output signal from the signal generator is applied to the fuel shut-off mechanism whenever the engine exceeds a maximum speed. In order to detect this condition, rpm-synchronous pulses are applied to at least one, and preferably two cascaded multivibrators which control an input of a gate, the other input of which receives the rpm-dependent pulses. The output of the gate is active only if the period of the rpm-dependent pulses is less than the sum of the unstable time constants of the multivibrators, in which case a final multivibrator is triggered and generates a fuel suppression control signal during a large fraction of two crankshaft rotations.
