Key research themes
1. How can variable compression ratio and active combustion chamber designs optimize combustion efficiency and emissions in internal combustion engines?
This research theme investigates the impact of variable compression ratio (VCR) systems and active combustion chambers (ACC) on improving engine performance, combustion stability, and emissions control. These technologies provide adaptive control over the compression dynamics and combustion process, aiming to enhance thermal efficiency, reduce knock, and enable flexible fuel use under varying load conditions.
2. What methods and parameters enable effective fault detection and diagnostics in internal combustion engines using operational sensor data?
Fault detection in internal combustion engines is critical for maintenance and operational reliability. This theme focuses on leveraging temperature, pressure, vibration, and other sensor measurements to identify incipient failures. The development of diagnostic indicators and algorithms to monitor key engine parameters under varying operational conditions aids early fault detection, minimizing downtime and preventing extensive damage.
3. How do computational and experimental analyses of engine components, such as engine blocks and advanced rotary designs, contribute to thermal management and efficiency improvements in internal combustion engines?
Efficient thermal management and understanding of mechanical stresses in engine components are essential for enhancing durability and performance in internal combustion engines. This theme encompasses research employing computational fluid dynamics (CFD), finite element analysis (FEA), and experimental motoring tests to assess temperature distribution, heat dissipation, friction, and aerodynamic flow around components or novel engine architectures like rotary engines.
