Abstract
A fuel injection control apparatus for use of an engine. The apparatus varies a minimum amount of fuel to be injected into the engine according to such conditions as the engine speed increases or decreases. When the engine speed increases, a first minimum amount of fuel is set in low and intermediate engine speed zones and the first minimum amount is converted to a second minimum amount of fuel which is less than the first minimum amount in a high engine speed zone. Contrary to this, when the engine speed decreases, the second minimum amount of fuel is set in high and intermediate engine speed zones, and the second minimum amount of fuel is converted into the first minimum amount of fuel in the low engine speed zone. Thus, according to the increase or decrease in an engine speed, a minimum amount of fuel is varied with a hysteresis.
