Abstract (en)

[origin: WO8100020A1] A fuel injection device of the type for correcting an air/fuel ratio by controlling the flow rate of a fuel metering gate disposed in a fuel supply passage with air flow detecting means for detecting the air flow intaken into an engine and by controlling fuel amount with a solenoid valve which is opened or closed by a detection signal indicative of the operating state of the engine. A second solenoid valve is disposed in parallel with the above solenoid valve and is opened or closed by the signal to correct the basic air/fuel ratio set by the relationship between the air flow detecting means and the fuel metering gate, thereby maintaining the air/fuel ratio at desired constant value.
