文摘

Effect of tri fuel (ULSD, H2, CH4) on combustion and engine emissions was examined. Fuel with high CH4 content (H50-M50 and H25-M75) tend to reduce NOx formation. Fuel with high H2 content (H75-M25 and H50-M50) tend to reduce PM formation. Increasing the percentage of H2 in the feed gas improved the NOx reduction. The hydrocarbon-SCR catalyst has shown satisfactory performance in NOx reduction.
