  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To control the air-fuel ratio correctly even in the low speed operation of an engine by correcting and controlling the minimum electrifying time of an electromagnetic fuel injection valve according to the revolutionary speed of the engine.
CONSTITUTION: In the low speed operation of an engine, the sucked air discharge is brought near to zero by the perfect closing of a throttle valve 13, and the pulse width t of a basic injection pulse output from a computing circuit is greatly shortened. Consequently, the driving pulse of an injection valve 12 is made to correspond to the pulse width t' of a pulse given from a frequency dividing circuit 21 and a wave-form shaping circuit 24 by a pulse width comparing circuit 22. That is, one input terminal of a comparator 25 is connected with the output terminal of an F-V converter 26 to generate a revolutionary speed signal proportional to the revolutionary speed of the engine by the frequency-voltage conversion of an ignition primary signal, while another terminal is connected with the source of comparative reference voltage, for changing and controlling the pulse width t' according to the number of revolutions of the engine per minute.
