Abstract
An electrical pressure signal that varies directly in magnitude with changes of fuel line pressure at the fuel injector is raised to a selected mathematical power. This signal is then differentiated to detect the negative rate thereof that occurs at the point of inflection upon the start of fuel injection and a 'start of fuel injection' output signal is produced in response to the detection of the point of inflection as indicated by the negative rate.
