Nitrogen Ozides Emission Characteristics of Diesel Engine Fuelled by GTL Fuel
(0) 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 NOx emission and the main constituents of NO, NO2 and N2O are analyzed. According to the results, the NOx Emission of different GTL blends shows no great differences, and as load increases, the differences become relatively greater. The total NOx emission is mainly composed of NO and NO2.The NO emission of the blends increases as load rises, and NO occupies the biggest proportion of the total NOX emission. NO2 also occupies comparatively big proportion., The NO2 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 NO2.The emission of N2O 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 N2O. As the blending proportion of GTL increases, the NOx and NO emission show greater decrease, while NO2 emission shows comparatively small increase.
