초록

A control system for an internal combustion engine includes a fuel injection control system having a first mode, wherein fuel injectors are controlled based on engine condition data supplied by a first group of sensors, and a second mode wherein fuel injectors are controlled based on engine condition data supplied by a second group of sensors. During normal operation of the engine, the control system switches between the first and second control modes based upon an engine operating condition (e.g., engine speed and/or engine load). If one of the sensors ...
