- Abstract
- A new method that optimizes a control of hydrocarbon(HC) addition to diesel exhaust gas for HC type DeNOx catalyst system has been developed. these catalysts are the HC-DeNOx catalyst in this paper. The system using HC-DeNOx catalyst requires quantity of hydrocarbons addition in the inlet gas of the catalyst, because the HC concentration in a diesel engine is so low that the HC is not sufficient for NOx conversion. Generally ambient temperature in the exhaust manifold is 250~350 degrees, so spray behavior in this case is different from that of any other condions. This research shows spray behavior of injected hydrocarbons in the transparent exhaust manifold.
