ABSTRACT:
One embodiment of the present invention is an internal combustion engine system that includes an internal combustion engine, a turbocharger with a compressor and a turbine and a gas flow pathway defined therebetween, one or more pressure sensors to detect pressure along the gas flow pathway, an emission control device structured to receive exhaust from the turbocharger, and a controller responsive to input from the one or more pressure sensors. The controller determines a control signal indicative of turbine outlet temperature as a function of such input, and selectively generates an output signal to adjust temperature of the exhaust provided to the emission control device from the turbocharger in response to the control signal.
