Performance and Emission Characteristics of a Diesel Engine Using Ammonia/Diesel

With the increasingly serious environmental pollution caused by the use of traditional fossil fuels, the development of new green energy has become an important issue. In the present study, the combustion of ammonia/diesel dual-fuel in the diesel engine are investigated numerically. Performance characteristics and emission characteristics are analyzed with different proportions of ammonia mixed with diesel. The results show that with the increase of ammonia ratio, the output power of the engine and the temperature in the cylinder are reduced. Though the NO
x
emissions increase, the CO
x
emissions are greatly reduced. In general, ammonia has the potential to be used in diesel engine effectively as an alternative fuel.
