Dimethoxy Methane in Diesel Fuel: Part 2. The Effect of Fuels on Emissions of Toxic Air Pollutants and Gas/Solid Phase PAH Using a Composite Of Engine Operating Modes 2001-01-3628
A weighted composite of four engine-operating modes, representative of typical operating modes found in the US FTP driving schedule, were used to compare engine-out emissions of toxic compounds using five diesel fuels. The fuels examined were: a low-sulfur low-aromatic hydrocracked diesel fuel, the same low-sulfur fuel containing 15% v/v dimethoxy methane, a Fischer-Tropsch fuel, a CARB fuel, and a EPA number 2 diesel certification fuel. A DaimlerChrysler OM611 CIDI engine was operated over 4 speed-load modes: mode 5, 2600 RPM, 8.8 BMEP; mode 6, 2300 RPM, 4.2 BMEP; mode 10, 2000 RPM, 2.0 BMEP; mode 11, 1500 RPM, 2.6 BMEP. The four engine operating modes were weighted as follows: mode 5, 25/1200; mode 6, 200/1200; mode 10, 375/1200; and mode 11, 600/1200. Each operating mode and fuel combination was run in triplicate. An analysis of variance of fuels showed that, in general, the 15% v/v dimethoxy methane fuel and the Fisher-Tropsch fuels had significantly lower (p < 0.05) emissions of measured compounds compared to the remaining fuels and were statistically indistinguishable from each other.
