Automatic combustion controller for internal-combustion engine

Abstract

Abstract PURPOSE:To improve the extent of engine drivability as maintaining a fuel-cut effect, by installing a suction control device controlling a suction quantity to an engine and also a suction variable device making the suction quantity to the engine variable. CONSTITUTION:A throttle valve 7, a flow control valve 10, a main passage 11 and a subpassage 9 constitutes a suction variable device 12 as a whole. An air flow meter 6, a throttle valve opening sensor 8 and a sensor group 13 constitutes a driving state detecting device 14, and a signal out of this device 14 is inputted into a control unit 20 which outputs a control signal SV and operates the suction variable device 12. And, an ignition signal SP is outputted to an ignition device 27. Thus, engine drivability is improvable as maintaining a fuel-cut effect.
