抄録(英) | The study was conducted on a pent-roof spark-ignited single-cylinder engine modeled from a large-bore medium-duty engine. A direct injection (DI) system capable of injecting H2 at 170 bar was integrated into the cylinder head. Both, lean and stoichiometric operation of the engine was explored in conjunction with various injection strategies. The results indicated that a stratified combustion strategy was able to increase the knock-limited load of the engine. This strategy also demonstrated increased efficiency compared to a homogeneous combustion mode and produced lower NOx at comparable loads. The diffusion-like combustion enabled by post-spark injection successfully demonstrated further knock mitigation and NOx reduction but was limited in performance due to challenges associated with in-cylinder mixing and DI injector flow rate. 翻訳 |
