Abstract
A method adjusts a pulse width of a signal. The method provides a fixed voltage input trigger pulse (), of a certain pulse width, to a pulse width generator circuit () and provides an output pulse () from the pulse width generator circuit such that a pulse width of the output pulse is longer than the certain pulse width, without changing a voltage or frequency of the input trigger pulse. The method is used to drive an injector of a diesel reductant delivery system to inject fluid into an exhaust flow path.
