The use of nonequilibrium plasma generated by nanosecond discharges to ignite fuel/air mixtures, known as transient plasma ignition (TPI), has been shown to effectively reduce ignition delay and improve engine performance relative to spark ignition for combustion engines. While this method is potentially useful for many engine applications, at present the underlying physics are poorly understoo...

This paper takes a first step towards model-based feedback control for the transition between spark ignition (SI) and homogeneous charge compression ignition (HCCI) combustion modes by approaching the transfer out of SI operation during the SI into HCCI transition in a closed-loop control framework. The combustion mode switch is taken to be directly from SI to HCCI without an intermediate combu...

Cardiac excitation-Ca2+ release coupling is, in essence, a tale of two molecules, sarcolemmal voltage-gated L-type Ca2+ channels (LCCs) and intracellular ryanodine receptors (RyRs), communicating via the Ca2+-induced Ca2+ release mechanism. Recent advances have provided a microscopic view of the intermolecular Ca2+ signaling between LCCs and RyRs. In a dyadic junction or a "couplon", LCCs open ...

The introduction of downsized, turbocharged Gasoline Direct Injection (GDI) engines in the automotive market has led to a rapid increase research on Low-speed Pre-ignition (LSPI) and super-knock as abnormal combustion phenomena within last decade. former is characterized an early ignition fuel–air mixture, primarily initiated by oil–fuel droplet or detached deposit. Meanwhile, occasional develo...

The increasing industrialization and motorization of the world has led to a step rise for the demand of petroleum-based fuels. Petroleum-based fuels are obtained from limited reserves. These finite reserves are highly concentrated in certain regions of the world. Therefore, those countries not having these resources are facing energy/foreign exchange crisis, mainly due to the import of crude pe...
