Study of Model-based Cooperative Control of EGR and VGT for a Low-temperature, Premixed Combustion Diesel Engine

A low-temperature, premixed combustion concept, called Modulated Kinetics (MK) combustion, has been developed that reduces emissions of nitrogen oxide (NOx) and smoke simultaneously. This new combustion concept requires heavy exhaust gas recirculation (EGR) to reduce the NOx emission and combustion noise. However, there is an interaction between the effects of controlling exhaust gas recirculation (EGR) and the variable geometry turbocharger (VGT). This makes controlling both the EGR rate and air mass flow rate more difficult under transient operating conditions. Therefore, the authors investigated a cooperative control of EGR and VGT in an effort to control the accuracy of both the EGR rate and the air mass flow rate. This paper presents an approach through the application of a control system CAD program and rapid prototyping tools to improve transient operating states by referring to a model-based EGR and VGT control algorithm. Furthermore, a prototype car was used to clarify the effect of the algorithm that was built through the simulation. The results of simulation and experiment, which demonstrate the effectiveness of this optimized transient control, are described.
