HCCI Diesel Engine Control Design using Advanced Simulation with Real Time Capabilities
Abstract
An engine model is a very flexible tool to perform a large amount of tests over a wide
range of operating conditions and to access to more detailed information than those available with
experiments. Therefore, the use of the numerical engine simulation in the control development process
can significantly reduce the test time needed on real hardware while providing more information for
understanding the system physics. Based on high-performance physical models such as HCCI
combustion model, the virtual engine simulator is able to support the control design from controller
development to real-time calibration.
The aim of this communication is to show the relevance of using such a model-based approach for
current control issues. The demonstration is achieved through the challenging case of Diesel HCCI
combustion engine. As an alternative to expensive and complex after-treatment solutions, Diesel HCCI
engine takes benefit of high exhaust gas recirculation rate to limit in-cylinder pollutant production.
Therefore, it is recognized as one of the most promising ways for new generation of CI engines but also one of the most complex engine technologies to control due to the sensitiveness of HCCI combustion mode to small perturbations.
