Abstract
Intake throttle valvestodisposed on the intake pipestofor each cylinder of a multi-cylinder engineare provided with motorstofor controlling valve opening of the intake throttle valves. The microprocessorcontrols throttle valve opening in response to a degree of stepping on an accelerator pedalin cooperation with a program memoryA. The control of valve opening by each motor is sequentially subject to time division processing in the exhaust stroke of each cylinder, and a current valve opening is stored and held by a feedback control circuit sectionB,C in the other strokes, thereby the control burden on the microprocessor being reduced.
