Research has shown that variable valve timing (VVT) can improve significantly the performance of internal combustion (IC) engines, including higher fuel efficiencies, lower emissions, and larger torque outputs at each point of the engine map. To achieve independent and continuous VVT for each valve, an electromechanical valve drive (EMV) system was proposed previously, whose feasibility with lo...

Taper intake ports are effective in improving the charging efficiency of small-scale rotary engines (REs), but it is unclear how their structural parameters affect in-cylinder flow field and combustion characteristics. For this reason, effects diameter-length ratio (D/L) an port on characteristics a RE were numerically investigated by utilizing three-dimensional computational fluid dynamics (CF...

It is well known and widely accepted that the integration of research and teaching in a problem-based educational setting helps to foster deep learning among students. In this paper, we describe how a patent on a rotary diesel engine, which had failed to work in practice, was used to link undergraduate research and teaching activities by orchestrating two design courses around this patent. Lear...
