Study on effects of ammonia-diesel blends in CI engines

Green Car Congress

An international team from the Middle East has investigated the characteristics of diesel engines powered by petroleum diesel fuel blended with different volumetric percentages of aqueous ammonia. Since 40%, 50%, and 60% of NH 4 OH have lower heating values than diesel, BSFC is reduced by 7.15, 10.4%, and 15.38%, respectively.
