ABSTRACT:
In a fuel injection system for an internal combustion engine the opening time of the injectors is proportional to the amount of fuel supplied. In the system having an exhaust gas sensor closing the control loop, the sensor compensates for both barometric and altitude changes; however, until the sensor is sufficiently warmed up or for a predetermined period of time the herein disclosed altitude compensation system provides control information for injector timing to account for changes due to barometric and altitude changes.
