| 摘要： | The United States Air Force can utilize B20 biodiesel fuel to partially meet EPAct requirements for alternative fuel use, and to lower criteria pollutants except for NOx. Relatively minor production component changes, and selected minor operating condition changes can alter engine out NOx emissions with biodiesel fuels in a 6.5L HMMWV engine. For a nonroad ISO 8178 test cycle, weighted average Smoke/PM emissions can be similar to DF-2 levels at the condition that gives equivalent NOx emissions with B20 biodiesel fuel. In other words, Smoke/PM emissions with B20 biodiesel can be traded-off for improved NOx emissions. For the 6.5L HMMWV engine tested the composite control strategy did not severely impact emissions or fuel consumption when the engine operated on JP-8 fuel. |
