Abstract
A method to estimate real-time exhaust pressure in a compression ignition engine with variable geometry turbocharger and an EGR by adding the turbocharger RPM, the engine RPM, EGR value position and intake manifold pressure to determine a final turbocharger turbine inlet pressure to control NOx emissions.
