This work analyzes NOx reduction in a marine diesel engine using ammonia injection directly into the cylinder and compares this procedure with water injection. A numerical model based on the so-called inert species method was applied. It was verified that ammonia injection can provide almost 80% NOx reduction for the conditions analyzed. Furthermore, it was found that the effectiveness of the chemical effect using ammonia is extremely dependent on the injection timing. The optimum NOx reduction was obtained when ammonia is injected during the expansion stroke, while the optimum injection timing using water is near top dead center. Chemical, thermal, and dilution effects of both ammonia and water injection were compared. The chemical effect was dominant in the case of ammonia injection. On the other hand, water injection reduces NOx through dilution and, more significantly, through a thermal effect. Full article

Title: Numerical analysis of NOx reduction using ammonia injection and comparison with water injection

María Isabel Lamas Galdo

Abstract: This work analyzes NOx reduction in a marine diesel engine using ammonia injection directly into the cylinder and compares this procedure with water injection. It was verified that ammonia injection provided more than 80% NOx reduction with a negligible effect on carbon dioxide, carbon monoxide, and hydrocarbon emissions, as well as brake-specific fuel consumption. Chemical and physical effects of water and ammonia were studied. The chemical effect was stronger than the physical one in the case of ammonia injection and the opposite in the case of water injection. Furthermore, it was found that the strength of the chemical effect using ammonia injection is extremely dependent on the injection instant. Ammonia must be injected during the expansion stroke.
