A new ignition-combustion concept named PCC (Plume Ignition Combustion Concept). which ignite rich mixture plume in the middle of injection period or right after injection of hydrogen is completed. is proposed by the authors in order to reduce NOx emissions in high engine load conditions with minimizing trade-offs on thermal efficiency. In this study fundamental requirements of hydrog... https://pipingrockers.shop/product-category/senna-leaves/
