Nitrogen Oxides Emission Characteristics of Diesel Engine Fuelled by GTL Fuel
This paper carried out nitrogen oxides emission characteristics of diesel engine fuelled by GTL fuel. A DI engine for passenger cars is chosen as the test sample, and 5 GTL blends with different mixing ratio are used. The emission behavior of the total NO<,x> emission and the main constituents of NO, NO<,2> and N<,2>O are analyzed. According to the results, the NO <,x> Emission of different GTL blends shows no great differences, and as load increases, the differences become relatively greater. The total NO<,x> emission is mainly composed of NO and NO<,2>. The NO emission of the blends increases as load rises, and NO occupies the biggest proportion of the total NO<,x> emission. NO<,2> also occupies comparatively big proportion., The NO<,2> emission is comparatively low during low and high load, while it is highest during medium load. The high temperature during high load is not in favor of the generation of NO<,2>. The emission of N<,2>O is extremely low, and it is mainly generated during low load; while during mid and high load, it is approximately zero. Lean combustion in cylinders is in favor of the generation of N<,2>O. As the blending proportion of GTL increases, the NO<,x> and NO emission show greater decrease, while NO<,2> emission shows comparatively small increase.
