Abstract | A method to control an engine to maintain turbine inlet temperature utilizes two temperature thresholds: a control initiation temperature and a maximum hardware temperature. An engine parameter is adjusted in a closed-loop manner based on an error, which is a difference between a setpoint temperature and the turbine inlet temperature. The setpoint temperature is initially the control initiation temperature. However, after control over turbine inlet temperature is established, the setpoint temperature ramps gradually to maximum hardware temperature. In one embodiment, the engine parameter is engine torque. Other engine parameters affecting turbine inlet temperature include timing and duration of fuel injection pulses, EGR rate, gear selection, and intake throttle position, any of which can be used in place of, or in combination with, torque for controlling turbine inlet temperature. Advantages of the invention include: torque reduction occurs smoothly, thus less disruptive to the vehicle operator, turbine inle |
