A diesel engine includes a fuel injection control system communicating with a barometric pressure sensor and throttle position sensor. An elevation compensation controller adjusts engine speed and fuel injection timing at high altitudes in response to the sensed barometric pressure and engine throttle position. Engine speed is increased or decreased by predetermined values with changes in barometric pressure and throttle position to optimize engine performance and efficiency under various pressure conditions while reducing exhaust emissions.
