Abstract
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.
