APPARATUS AND METHOD FOR LIMITING TURBOCHARGER SPEED |
摘要 |
<p>A system for limiting rotational speed of a turbocharger includes means for determining a change in an engine operating parameter, a fueling system responsive to a fueling signal to supply fuel to the engine, and a controller determining a fueling command that is air-to-fuel or oxygen-to-fuel control (AFC/OFC) limited under certain engine operating conditions and is otherwise not AFC/OFC limited. The controller is operable to produce the fueling signal as a function of the fueling command, and to further limit the fueling signal according to a turbocharger speed fuel limit in a to manner that limits the speed of the turbocharger to a first turbocharger speed limit whenever the fueling command is AFC/OFC limited. The controller is operable to remove the turbocharger speed fuel limit from the fueling signal when the change in the engine operating parameter exceeds a threshold value and the fueling command is thereafter no longer AFC/OFC limited.</p> |
