Effects of Pressure Variations and Combustion Duration on the Emission of Hydrocarbons and Nitric Oxide 760142

Emissions of nitric oxide and hydrocarbons are affected by various parameters, combustion duration interval being one of them that can alter the levels of nitric oxide in the exhaust. To some extent hydrocarbon emission depends upon the temperature particularly near the walls. Changes in combustion duration interval alters pressure history in the chamber by changing maximum pressure, rate of pressure rise and the time required for the maximum pressure to occur. This study looks at the relative effects of this on the nitric oxide formation and investigates the hydrocarbon emission when the flame initiation point is changed.
