Evaluation of 25-Percent ATJ Fuel Blends in the John Deere 4045HF 280 Engine

Abstract : A 25% blend of Alcohol to Jet (ATJ) and JP8 fuel was evaluated in the mechanically fuel injected John Deere 4045HF280 engine. Pre and post test full and partial load power curves and emissions were completed, and the engine was evaluated following modified procedures outlined by the 210 hr Tactical Wheeled Vehicle Cycle. The engine completed the full 210 hr of testing without experiencing any unusual performance degradation related to usage of the ATJ fuel blend. All results suggest that a 25% blend of ATJ could be use in place of typical JP8 in similar applications.
