Dual-Stage TC modeling and Calibration using 1D Simulation - Correlation with NVH quantities 2010-36-0305
This work brings and proposes a simulation methodology to
virtually investigate a 2-stage Turbocharger application for a
heavy duty diesel engine. The motivation of the work is the
research and development of an engine which is supposed to comply
with very restrictive emission regulation policies, namely Euro V,
VI and EPA 10, besides Tier 4 Final. Although emission level is,
itself, a main concern (mainly NOx and engine-out PM), the present
work present a methodology which covers air flow and boost ability
of the entire engine and it is designed to be able to properly
evaluate turbocharger designs possibilities (TC matching).
In order to find the unknowns of the physical problem and, then,
to verify the methodology success, some not usual measurements were
done, such as of TC shaft speed using NVH techniques. Also,
controlling techniques via simulation, e.g., two-stage TC
calibration using virtual PID's of efficiencies and discharge
coefficients were done to achieve a good model alignment between
simulation and dynamometer test acquired data.
