Abstract: A control and method for an internal combustion engine that includes an exhaust gas recirculation system to predict an intake manifold critical temperature (dew point) at which condensation would occur upon entry into exhaust gas recirculation. The control calculates the intake manifold critical temperature (IMT_Critical) as a function of predetermined, sensed or assumed values by processing an equation whose variables are occupied by the values. The control commands adjustments of exhaust gas recirculation operation in response to the calculation, preferably after the actual intake manifold temperature exceeds the IMT_Critical for a predetermined time.

Abstract: A method for controlling exhaust gas particulate emissions from a compression ignition internal combustion engine having a variable geometry turbocharger (VGT) includes the steps of determining backpressure across the engine and air mass flow into the engine, closing vanes of the VGT to provide air mass flow increase when backpressure is increasing, and stopping the step of closing the vanes of the VGT when a decrease in rate of change of air mass flow is determined.
