Method for Establishing Cool Flames and Flameless Fuel Oxidation with Zero Emissions Using Non-Equilibrium Plasma Activation

Current engines and combustors run at high temperature, which leads to problems of engine knocking, soot and NOx emissions, and difficulty in combustion control. On the other hand, low-temperature combustion and fuel...
