Control of EGR and VGT for Emission Control and Pumping Work Minimization in Diesel Engines

Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. Control structures are proposed and investigated for coordinated control of EGR valve and VGT position in heavy duty diesel e...

Robust Nonlinear EGR and VGT Control with Integral Action for Diesel Engines

A robust non-linear multivariable control design with integral action is proposed and investigated for control of EGR valve and VGT position in heavy duty diesel engines. The main control goal is to regulate oxygen/fuel ratio and intake manifold EGR-fraction. These are chosen as main performance variables since they are strongly coupled to the emissions. A recently developed non-linear control ...

Non-linear Compensator for handling non-linear Effects in EGR VGT Diesel Engines

A non-linear compensator is investigated for handling of non-linear effects in diesel engines. This non-linear compensator is a non-linear state dependent input transformation that is developed by inverting the models for EGR-flow and turbine flow having actuator position as input and flow as output. The nonlinear compensator is used in an inner loop in a control structure for coordinated contr...

Gas flow observer for Diesel Engines with EGR

Due to stricter emission legislation, there is a need for more efficient control of diesel engines with exhaust gas recirculation(EGR). In particular, it is important to estimate the air/fuel ratio accurately in transients. Therefore a new engine gas flow model has been developed. This model divides the gas into one part for oxygen and one part for inert gases. Based on this model an observer h...

Novel Turbocharger Concept and Control Strategy for Diesel Passenger Car

In a modern small sized passenger car fitted with a common rail diesel engine, turbo-lag is an important factor which hampers its performance. This paper discusses the basics of turbo-charger and VGT and some of the methods employed to reduce the turbo-lag in CRDI diesel engine. A novel turbocharger concept, approach to design, the control strategy and advantages of the concept are explained.
