Direct injection of both fuels in RCCI may offer a way to decrease HC and CO emissions without sacrificing efficiency and NOx/PM benefits

Green Car Congress

However, similar to other LTC strategies, RCCI suffers from levels of UHC and CO that are considerably higher than in conventional diesel combustion. These zones ignite earlier, thereby advancing the combustion event and increasing cylinder temperatures, causing an increase in NO x and PM and a decrease in CO. Wissink et al.
