Abstract

As for the advanced energy applications of plasma and ionic liquid as a functional fluids, plasma assisted ignition for internal combustion engines by nano second pulsed discharge at high pressure and high temperature conditions has been introduced. Furthermore, the ionic liquid electrospray for the space propulsion has been discussed with its fundamental characteristics.
