Fuel injection control apparatus

Abstract

A fuel injection control apparatus of a four cycle engine having six cylinders comprises: a crank angle detection device for detecting the crank angle of the four cycle engine; a first computation device for computing the quantity of fuel, which is injected in a predetermined stroke of a four stroke cycle, at a first computation timing; a second computation device for computing the quantity of fuel, which is injected one stroke before the predetermined stroke, at a second computation timing 240 degrees ahead of the crank angle of the first computation timing; and a third computation device for computing the quantity of fuel, which is injected two strokes before the predetermined stroke, at a third computation timing 120 degrees ahead of the crank angle of the second computation timing. The fuel injection control apparatus is adapted to decrease interruptions by computations for fuel injection control in the six cylinder engine, and reduce control load.
