What is stratified combustion?

Stratified combustion refers to the burning of fuel in layers where each layer has a varying air-fuel ratio. This technique enables different areas within the combustion chamber to experience different combustion characteristics, optimizing the efficiency and performance of the engine. By allowing certain regions to operate with a rich mixture (more fuel, less air) and others with a lean mixture (more air, less fuel), it can lead to more complete combustion in some areas while minimizing emissions in others. Such a method enhances the overall efficiency of the combustion process and can help in achieving a balance between power output and emissions.

This concept differs from other combustion techniques, such as those that rely on a uniform air-fuel ratio across the entire combustion chamber, which can result in less efficient fuel usage and increased emissions. Stratified combustion is specifically valued for its ability to tailor combustion characteristics based on operational demands, making it an important innovation for improving engine technology and performance.
