Experimental Study on the Performance of the Engine Fueled with DME-Methanol Blends

Abstract:

Performance test of the engine fueled with DME-methanol blends was conducted on a 4102BQ diesel engine. The results show that: by increasing the fuel pump plunger diameter, delaying injection timing, and reducing nozzle-opening pressure, the rated power of the engine, fueled with DM90 blends (Mass ratio of DME and methanol is 9:1), descended 13.97% relative to the original diesel engine, but the soot emissions did not appeared in all test conditions. In full load condition, NO_x emissions declined by 55.1%, CO emissions fell by 65.8%, but HC emissions increased by 21.6%.
