摘要： A fuel control system for an internal combustion engine for controlling fuel supply rate on the basis of the output signal of a vortex flowmeter having variable-frequency filter means, capable of accurately measuring intake air flow to control the fuel supply rate accurately avoiding the erroneous measurement of noises generated during the rapid deceleration of the engine in which the throttle valve is shut. The fuel supply system has operating mode detecting means for detecting the operating mode of the engine, and passband fixing means for fixing the passband of the variable-frequency filter means at a predetermined passband when the operating mode detecting means detects that the engine is in a predetermined deceleration mode. The passband of the variable-frequency filter means is fixed at the predetermined passband while the engine is in the predetermined deceleration mode to enable accurate control of fuel supply rate by eliminating noise signals which is generated during the predetermined deceleration mode and superposed on the operating mode detection signal. When the engine is accelerated during a time period subsequent to the end of the predetermined deceleration mode, the fixation of the passband of the variable-frequency filter means is cancelled.

摘要： A fuel controller for an internal combustion engine senses misfiring in an engine cylinder by sensing changes in the rotational speed of the engine between prescribed crankshaft angles due to a reduction in torque when misfiring occurs. When misfiring occurs, the supply of fuel to the misfiring cylinder is cut off for a prescribed number of engine rotations and then the supply of fuel is restarted. A warning indicator is turned on as long as misfiring is detected by the misfiring sensor.

摘要： A fuel controller for an internal combustion engine has a Karman vortex air flow sensor for sensing the air flow rate into the air intake pipe of the engine and producing an electrical output signal having a frequency which is proportional to the air flow rate. A load sensor determines the air flow rate into an air intake pipe based on the output of the air flow sensor. A determining mechanism determines whether the output of the air flow sensor is reliable. A calculator calculates the actual air intake rate into the engine according to a first formula which employs the most recent output of the load sensor when the determining mechanism determines that the output of the air flow sensor is reliable, and it calculates the actual air intake rate according to a second formula which ignores the most recent output of the air flow sensor when the determining mechanism determines that the output of the air flow sensor is not reliable.
