Web2 days ago · The neural network regression analysis indicates that NOx emissions are strongly related to the peak in-cylinder temperature, spark timing, and lambda. The NOx emissions at peak loads can be reduced by leaner operation using an enhanced intake-boosting system or exhaust gas recirculation. Alternatively, NOx can be reduced using … WebJan 1, 2024 · While thermal and prompt NOx mechanisms can be significant for fossil fuel combustion applications, in biomass combustion, the temperature in the combustion chamber is typically below 1300 °C (900 °C-1000 °C with peak values up to 1300 °C), therefore, NOx formation is dominated by the fuel-N mechanism.
