ABSTRACT:
A method of calculating fuel injection quantities, as determined by the initiation and duration of fuel injection, in an internal combustion engine in response to repetitive engine operating parameters measured during engine operation. The quantity of fuel injected into a cylinder of a multicylinder engine may be determined through measurement of an operating characteristic of that cylinder immediately prior to injection. The timing of injection may also be responsive to the measurement of the engine operating characteristic which may not be uniformly repetitive.
