  collision when the equipped vehicle approaches a
  pedestrian or another vehicle 
• If the driver does not react to the warnings, the
  system automatically applies the brakes to avoid
  or considerably reduce the effects of the
  collision

  specified headway-gap from the vehicle ahead
• Headway Alert warns drivers when their vehicle is
  less than one-second away from the vehicle ahead,
  helping them to avoid tailgating.
• With the Stop Go feature, the system provides
  speed control down to a complete stop, expanding
  ACC operation for high-congestion, stop and go
  traffic

30
Forward Collision Warning

• Alerts drivers to slower moving and stopped
  traffic ahead so that they can take evasive
  action
• Helps reduce the severity of an unavoidable crash
  by notifying the driver to take action
• One multi-purpose radar enables ACC, forward
  collision warning and pre-crash sensing

• Direct Injection
• Most DFI systems are of the Spark Ignited Direct
  Injection (SIDI) type. However DFI makes other
  technologies possible, such as stratified fuel
  charge and Homogeneous Charge Compression
  Ignition (HCCI).

40

• Direct Injection (continued)

• These systems generally operate at a higher fuel
  pressure to achieve maximum fuel atomization.
• In addition, the direct injection system achieves
  greater efficiency by enhancing fuel mixing
  through internal chamber turbulence
• DI has a 10-15 economy increase over IDI.

41
Efficiency, Economy Emissions

• Variable Valve Timing
• Variable valve timing is being used to decrease
  vehicle emissions, and increase engine
  performance
• This is accomplished by varying the valve
  duration depending on the current operating
  condition.
• At high engine speeds, there is a benefit to
  adding additional air to an engine

42
Efficiency, Economy Emissions

• Variable Valve Timing
• At low speeds the extra air is a detriment to the
  combustion process. Some of the air-fuel mixture
  will not be burned and will escape from the
  combustion chamber
• These systems provide benefits long sought by
  vehicle manufacturers to control engine intake
  and exhaust valves.
