Abstract:
1. An apparatus for controlling a fuel injector, comprising: a rail pressure sensor coupled with a rail of the fuel injector and operable to transmit a rail pressure signal as a function of the rail pressure during a zero fuel condition; an engine speed sensor operable to be coupled with an engine, the engine speed sensor operable to transmit an engine speed signal as a function of the engine speed of the engine during the zero fuel condition; and a controller coupled with the rail pressure sensor to receive the rail pressure signal and with the engine speed sensor to receive the engine speed signal, the controller operable to transmit an injection signal to the fuel injector that is operable to cause the fuel injector to inject fuel into the engine, the controller further operable to determine an adjustment to the injection signal as a function of the rail pressure signal and the engine speed signal received during the zero fuel condition.
