Aggressive Deceleration Fuel Shut-Off (Adfso) - Ford Escape 2013 Manual

2.5L iVCT I-4
• 168 horsepower @ 6000 rpm
• 170 lb.-ft. of torque @ 4500 rpm
• Mated to the 6-speed SelectShift
Automatic transmission
• intake variable cam timing (iVCT)
• Intake manifold provides optimum flow of air
and fuel into the cylinders, which helps contribute
to performance
• Aluminum cylinder head with 4 valves per cylinder
– Intake ports designed to optimize airflow and
fuel/air mixing for efficient internal combustion
at light loads
– Exhaust ports improve flow and help contribute
to lower smog-forming emissions
• Exhaust manifold has been designed for optimum
flow for better engine performance
• Balance shaft helps lessen engine vibration and
deliver a smooth, V6-like feel
• Standard on S (FWD)
intake Variable Cam Timing (iVCT)
• Allows the camshafts to operate the intake valves
at different times in the combustion cycle, based on
speed and load
• Adjusts cam timing to provide optimum performance
and fuel economy
• Outstanding efficiency under low load conditions
such as idling or highway cruising
• Remarkable power when accelerating
What Smart Charging Is
• Standard feature that helps
improve fuel efficiency
• A regenerative electrical
charging system that
optimally charges the
battery, instead of having
the alternator charging the
battery, anytime the engine
is running

Aggressive Deceleration Fuel Shut-off
(ADFSO)
• Helps maximize fuel efficiency by temporarily
• System is automatic and requires no interaction
NoTe: See the Powertrain section in the Source Book
Appendices or on eSourceBook for more information.
FEAD (Front-End Accessory Drive)
Belt Technology
• Helps improve fuel efficiency
• Eliminates the need for an accessory belt tensioner
• FEAD belt is able to stretch itself and contract back

Smart Charging
How It Works
• Smart charging increases alternator output
when the vehicle is braking or decelerating,
converting the moving (kinetic) energy into
electric energy
– Since there is no additional engine accessory
belt load to energize the battery, less fuel is
used by the engine
– The captured energy is used to charge the
battery and maintain optimum operating
levels of the electrical system
• Communicates with the ADFSO system to
ensure the battery is being optimally charged
– ADFSO will maintain normal engine operating
during deceleration should the battery require
additional charging

interrupting fuel delivery and consumption when
the vehicle normally slows down, while maintaining
normal engine operation
from the driver
to drive the alternator, water pump and air
conditioning compressor drive pulleys, helping
reduce overall vehicle weight
when additional loads are imposed on it
Key Benefits
• Helps the engine
