A Study of Fuel Nitrogen Conversion, Performance, and Emission Characteristcs of Blended SCR-II in a High-Speed Diesel Engine 810251
Engine operation with blended SRC-II and pyridine doped diesel fuel were compared relative to regular #2 diesel fuel in a 4-stroke, turbocharged, direct injection, high speed commercial diesel engine.
The brake specific fuel consumption, (M-Joule/hp-hr), turbocharging, combustion characteristics and smoke did not change between blended SRC-II and regular #2 diesel fuel. This was expected since the sample fuels were blended to be of the same cetane number. The maximum torque, hydrocarbon and NOx emissions were higher for blended SRC-II. There was essentially no difference in the NOx measurements of the pyridine doped fuel and regular #2 diesel fuel.
The NOx emission increase for the blended SRC-II is believed to be caused by the increased aromatic content of the blended SRC-II and not the fuel nitrogen conversion.
