Development of a Unique Plasma Burner System for Emission Reduction During Cold Start of Diesel Engines

Plasma burner of a new concept is suggested, developed and characterized as a unique SCR catalyst warm-up technology. This study shows a promising potential of using a plasma burner for rapid warm-up performance, minimizing fuel consumption and maximizing flame stability regardless of the temperature, oxygen concentration and flow velocity of exhaust gas in diesel engines. Since the oxygen and fuel source of the plasma burner are separated from the exhaust gas line, the performance of the plasma burner can be used regardless of engine conditions, such as engine speed and oxygen concentration.

This study shows that the plasma burner can be used as an effective and promising tool for clean and energy efficient NOx and HC aftertreatment system for diesel engines.
