Other Fuel Savers
The Fusion gas powerpacks incorporate other advanced fuel-saving and performance technologies, including:
- Electric Power Steering (EPS). The 2010 Fusion has a rack- or belt-driven EPS system. Available on the 2.5-liter and 3.0-liter engines, energy consumption of an EPS system is typically less than 7 percent of a conventional hydraulic rack and pinion power steering system, contributing to less fuel consumption. Ford has committed to fit up to 90 percent of its Ford, Lincoln and Mercury products with EPS by 2012 and first introduced a column-based EPS system on the 2008 Ford Escape and Mercury Mariner.
- Adaptive Spark Ignition. Included on the V6 configurations, this system can sense what type of fuel is being injected into the motor and communicates the information to the powertrain control module (PCM), which adjusts the spark accordingly. The ignition system features two knock sensors rather than one to further improve performance. These two sensors detect the presence of uncontrolled burning in the chambers more accurately, so the control module can retard engine timing as needed to eliminate the potential for engine knock and pinging.
- Aggressive Deceleration Fuel Shut-off. The 3.0-liter V6 also regulates its gas consumption by using aggressive deceleration fuel shut-off for an efficiency improvement of approximately 1 percent. When the driver releases the accelerator pedal to slow down, the system temporarily turns off the fuel. The flow of fuel seamlessly resumes when the vehicle reaches a low speed or when the driver accelerates again. The system uses the transmission to keep the engine running at a low, more efficient operating point whenever possible. This system will be added to the 2.5-liter lineup later in the 2010 model year.
