混合料开始生成NOx温度约为300℃,此时NOx浓度较低。随着温度升高,NOx浓度逐渐上升,在600℃出现第一个峰值,约20×10-6;随后NOx浓度迅速升高,在780℃出现第二个峰值,约120×10-6,然后逐渐下降至零。
The temperature at which the mixture starts to generate NOx is about 300°C, and the NOx concentration is low at this time. As the temperature rises, the NOx concentration gradually rises, with the first peak at 600°C; then the NOx concentration rises rapidly, with a second peak at 780°C, and then gradually drops to zero.
