Mid-level ethanol blend study: Chassis dynamometer study of flex fuel vehicles
The objective of this study was to determine the fuel efficiencies and emission profiles of flex fuel vehicles operating on different ethanol blends (E10, E20, E30, and E85). Nine vehicles were supplied by the State of Nebraska Transportation Services Bureau vehicle fleet. The vehicles tested were flexible fuel sedans with 3.0 L and 3.5 L engines and pickups with 4.7 L engines. An automotive repair company, "The Shop, Inc.", was contracted with to support the chassis dynamometer testing of the vehicles according to outlined test procedures. The dynamometer was able to simulate road and vehicle operating conditions while measuring engine speed, torque and horsepower produced at the wheels.
