Abstract: Diesel engines are of great challenges due to stringent emission and fuel economy requirements. Compared with the conventional turbocharger system, regenerative assisted system provides additional degrees-of-freedom for ...

Abstract: This paper presents a model of an electric variable valve timing (EVVT) system and its closedloop control design with experimental validation. The studied EVVT uses a planetary gear system to control the engine cam timing. ...

Abstract: Modern spark ignited (SI) internal combustion engines maintain their airtofuel ratio (AFR) at a desired level to maximize the threeway catalyst conversion efficiency and durability. However, maintaining the engine AFR ...

Abstract: Making future vehicles intelligent with improved fuel economy and satisfactory emissions are the main drivers for current vehicle research and development. The connected and autonomous vehicles still need years or decades ...

Abstract: Statefeedback gainscheduling controller synthesis with guaranteed performance is considered in this brief. Practical assumption has been considered in the sense that scheduling parameters are assumed to be uncertain. The ...

Abstract: Control-oriented models for automotive turbocharger (TC) compressors typically describe the compressor power assuming an isentropic thermodynamic process with fixed isentropic and mechanical efficiencies for power transmission ...

Abstract: A multi-objective optimization of a coupled casing treatment (CCT) for an axial transonic compressor is performed in this study. The coupled casing treatment is the basis axial slots with a circumferential groove located ...

Abstract: The rotating distortion generated by upstream wakes or low speed flow cells is a kind of phenomenon in the inlet of middle and rear stages of an axial compressor. Highly complex inflow can obviously affect the performance ...

Abstract: A surrogate-assisted optimization approach is an attractive way to reduce the total computational budget for obtaining optimal solutions. This makes it special for its application to practical optimization problems requiring ...
