For the Gas and Hydrogen plots, the predicted performance was better than the measured. In these plots, more mass was burned. For natural gas, it was the opposite. More fuel was actually burned compared to the predicted amount. In the tables, the measured model has a higher brake torque and brake power, but lower BSFC. The measured performance also shows higher IMEP and BMEP. 2.
Using plots, compare the NOx formation for each of the three cases. Which case resulted in the maximum Nox produced? What about the least? Provide reasoning as to why. Gas Natural Gas
Hydrogen The gas simulation resulted in the highest NOx concentration while the natural gas resulted in the least. This is due to natural gas having a low fuel nitrogen content, while gasoline has a much higher nitrogen content. 3.
Using plots, compare the Flame Speeds for each of the three cases. Which case resulted in the fastest flame speed? What about the slowest? Provide reasoning as to why.
