Abstract: A novel methodology is presented in this paper to reduce the burden of calibrating an engine model associated with a high number of parameters and nonlinear equations. The proposed idea decreases the calibration candidate ...

Abstract: Reduction of cold start hydrocarbon (HC) emissions requires a proper compromise between low engineout HC emission and fast lightoff of the three way catalytic converter (TWC). In this paper, a hybrid switching system is ...

Abstract: Estimation of relevant turbocharger variables is crucial for proper operation and monitoring of turbocharged (TC) engines, which are important in improving fuel economy of vehicles. This paper presents meanvalue models ...

Abstract: Stringent NOX emission norm for heavy duty vehicles motivates the use of predictive models to reduce emissions of diesel engines by coordinating engine parameters and aftertreatment. In this paper, a physics-based ...

Abstract: A novel decentralized control architecture is developed based on a feedback from the pressure difference across the engine which is responsible for the pumping losses and the exhaust gas recirculation (EGR) flow in diesel ...
