Engine Technologies - Ford 2013 User Manual

Mustang enthusiast customers will appreciate additional details behind the features and technologies giving
the 5.0 Ti-VCT V8 engine the balance of power AND fuel efficiency.
• Ti-VCT rotates the camshafts — two per each cylinder head — to advance or retard the cam timing,
maximizing engine power and fuel efficiency based on several measures including throttle input
• During the engine development stage, powertrain engineers went to the Ford Racing engineers, started with a
proven high-lift camshaft profile and then tuned it for the 4-valve-per-cylinder heads on the 5.0
• Extensive use of computer-aided engineering (CAE) and dynamometer testing was performed to fine-tune
the camshaft profile to maximize power and fuel efficiency
• Aluminum DOHC cylinder heads feature a compact high-performance roller finger valvetrain design leaving
more space for high-flow ports for free-breathing performance
• Cylinder head structure was designed to support high cylinder pressures and includes cross-flow cooling for
sustained high engine rpm use
• Aluminum engine block has optimized oil windage and drainback performance to help maintain proper
engine oiling under high rpm and high cornering use — conditions commonly seen at "track day" events
• Piston cooling jets help improve oil warm-up and help maintain cooler piston temperatures
• Specially designed tubular exhaust headers were developed to maximize exhaust pulse separation and
improve flow. The headers and crossover balance tube not only help generate more power, but are key to the
terrific sound coming from the dual exhaust outlets
Fail-safe Cooling System
• Standard on 5.0L V8 engines
• If the engine overheats, it automatically switches
from 8-cylinder operation to alternating 4-cylinder
operation
• The vehicle operates at limited engine power,
allowing the driver to travel a short distance to a
service facility
• The distance the vehicle can travel depends on load,
outside temperature and road conditions
Cam-torque Actuated Twin independent
Variable Camshaft Timing (Ti-VCT)
• Allows the camshafts to operate the intake and
exhaust 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

Aggressive Deceleration Fuel Shut-off
(ADFSO)
• Helps maximize fuel efficiency by temporarily
interrupting fuel delivery and consumption when
the vehicle normally slows down while maintaining
normal engine operation
• System is automatic and requires no interaction from
the driver
NOTE: See the Powertrain section in the Source Book
Appendices or on eSourceBook for more information.
ENGINEERING INSIGHT
Cold-air Induction
What It Is
• A cold-air induction system is standard for BOTH
Mustang engines
• It's called "cold-air" since the air filter is isolated
from the engine compartment and allows the
intake to "breathe in" cooler air from outside
How it Works
• By taking in cooler air, the intake charge can be
combined with more fuel than it can with warmer
air — what is often called a "richer" fuel mixture
• More fuel in the intake charge helps the combustion
cycle produce more power — and Mustang
customers always appreciate more power
