What typically happens to the combustion temperature in stratified combustion?

In stratified combustion, the combustion temperature does vary throughout the combustion process. This variation occurs because stratified combustion involves the layering of fuel and air within the combustion chamber, leading to different areas having different fuel-to-air ratios and, consequently, different combustion characteristics.

When fuel is introduced in a stratified manner, areas with a higher concentration of fuel may reach higher temperatures sooner compared to leaner areas. Additionally, as the combustion process progresses, changes in the mixture density and flow dynamics can also cause fluctuations in temperature.

In contrast, combustion processes that maintain a constant fuel-to-air ratio tend to have a more uniform temperature throughout. However, stratified combustion is specifically designed to create a more controlled and efficient burning process, which inherently leads to temperature variations as the combustion evolves.
