Abstract
As energy crises and environmental pollution become increasingly severe, internal combustion engines as mainstream power units face the dual challenges of improving thermal efficiency and reducing emissions. In response to these challenges, this study focuses on novel combustion technologies for performance optimization and proposes a technical solution based on the synergistic control of stratified combustion and multi-point ignition, addressing the limitations of traditional combustion modes. By constructing precise numerical simulation models and validating them experimentally, the study systematically analyzes the impacts of the new combustion technology on combustion stability, fuel adaptability, and emission characteristics. Results indicate that this technology can significantly enhance combustion efficiency by over 5% while effectively reducing NOx and particulate matter emissions by more than 20% and 30%, respectively. Additionally, the research elucidates the coupling mechanisms of stratified combustion and multi-point ignition under various operating conditions, providing theoretical support for the intelligent control of internal combustion engine combustion systems. The innovation of this study lies in the first-time integration of stratified combustion and multi-point ignition technologies, overcoming the bottleneck of single technologies that struggle to balance high efficiency with low emissions, thus laying a solid foundation for the design and development of next-generation internal combustion engines.
