Performance of ammonia fuel in a spark assisted compression Ignition engine

Recent studies concluded that the use of ammonia in SI engines is possible thanks to an ignition booster or promoter. In this paper, improvement premixed ammonia/air combustion for internal studied as a function performance and exhaust pollutants Spark-Assisted Compression Ignition single-cylinder engine, which supports higher compression ratio (CR). For first time, pure NH 3 was performed over large range engine operating conditions. The study concludes neat can be used range, here driven by intake pressure, using classical device with CR 14–17 at 1000 rpm. comparison previous data obtained current clearly shows potential mode, even very low loads various speeds (650, 1000, 2000 rpm), spite initial aerodynamic not optimized enhance flame-turbulence interaction. Kinetic simulations provide some explanations about emission behaviour, especially unburnt , H 2 NO x N O.
