Combustion vortex induction chamber achieves zero-emission ammonia-fueled ICE

https://www.wardsauto.com/industry-news/researchers-claim-breakthrough-ammonia-ice

"swirling flow promotes homogenous air/ fuel mix, improved combustion and reduced emissions...air entering through helical port develops into swirling patterns, while air from tangential port initially produces no vortical structure but when redirected by cylinder walls eventually generates swirling structures... best results in early stage of compression stroke when tangential port opening >25%, low variances of turbulent kinetic energy during intake stroke, and low variances of swirl center position during compression stroke"
