On the study of combustion process of internal combustion engines, the combustion process is usually studied in the time region.
在内燃机燃烧过程的研究中，通常把燃烧过程在时域上展开，即制取示功图。

The calculated results with this model are in agreement with the experimental data, and it can be used to predict the volatile combustion time for the high temperature region.
经实验验证，改进的模型与试验结果吻合良好，较大幅度地提高了高温段页岩挥发分燃烧时间预测精度。

Hot combustion gases from the pyrolysis region react with the charcoal to convert the carbon dioxide and water vapor into carbon monoxide and hydrogen.
