As the driver steps on the brake, the pump/motor forces hydraulic fluid out of a low-pressure accumulator and into a high-pressure accumulator, increasing the pressure of nitrogen gas stored there to 5,000 psi. During acceleration, the HLA system switches from the pump mode to the motor mode, the nitrogen gas forces the hydraulic fluid back into the low-pressure accumulator, and the pump/motor applies torque to the driveshaft through the clutch. If quick acceleration is required, the F-350's diesel engine works with the HLA system.<hr></blockquote><!--EZCODE QUOTE END-->Not exactly the same as what Tucker was working on, but not too entirely different, either.
