• Objectives
• Describe why idle reduction strategies and
  technologies must be considered
• Describe how idle reduction benefits health and
  the environment
• Explain the economic benefits of idle reductions
• Describe what energy security is and how idle
  reduction can be used to help attain it
• Explain some suggested actions to utilize idle
  reduction practices

3
Why Consider Idle Reduction?

• Petroleum and emissions reduction strategy
• Idle speed at which ICEs rotate under no
  throttle or load
• Tachometer displays engine speed
• Smooth engine operation for vehicle acceleration
  from stop and adequate oil pressure

4

• Transportation and convenience idling
• Technologies, policies, practices to reduce
  engine idle time
• Strategies and technologies to reduce both
  transportation and convenience idling

5

• Manufacturers
• Light-duty CAFE fuel economy and EPA emissions
  regulations
• Light-, medium-, and heavy-duty EPA emissions
• Mild hybrid systems
• Idle shutoff function
• Advanced engine technologies

6

• Consumers
• Purchase vehicles with idle reduction
  technologies
• Modify driving habits
• Plan trips to avoid traffic
• Consult the owners manual for optimal vehicle
  operation

7

• Advantages of Idle Reduction
• Reduced fuel consumption
• Fewer vehicle emissions
• Lower operating costs
• Increased engine life
• No-cost implementation

8

• Additional Points to Consider
• Possible capital investment
• Personal convenience may be compromised
• Be aware of local idling laws

9
Benefits of Idle Reduction

• Health and environmental rewards
• Reduced fuel costs
• Reduced dependence on foreign oil

10
Health Benefits

• Combustion of fuels produces harmful emissions
• Creation of PM and NOx
• Respiratory and cardiovascular complications
• Idle reduction reduces vehicle emissions

11
Environmental Benefits

• Emissions negatively affect the environment
• GHG formation, climate change
• Idle reduction reduced emissions

12
Economic Benefits

• Excessive idling unnecessary financial loss
• Industry opportunity for implementation of idle
  reduction technologies
• Reduced consumption financial benefit for all
  drivers

13
Energy Security Benefits

• Reduced idling reduced fuel consumption
• Reduced fuel consumption reduced reliance on
  foreign oil
• Nearly half of all petroleum used in the U.S. is
  imported

14
Idle Reduction Today and Tomorrow

• EPA standards for fuel economy and emissions
• More stringent standards more sophisticated
  technologies
• Light-, medium-, and heavy-duty applications
• Idle reduction strategies

15

• The Future of Idle Reduction
• CAFE standards for light-duty vehicles
• EPA-enforced regulations for all vehicles
• Standard idle reduction technologies and features
• Individualized actions and practice implementation

16

• Suggested Actions
• Know and practice vehicle manufacturer suggested
  operating procedures
• Plan trips to avoid sitting in traffic
• Turn off the engine if it idles for more than
  10-30 seconds as recommended by the California
  Consumer Energy Center
• Implement heavy-duty technologies if available
• Utilize TSE locations

17

  technologies must be considered?
• Describe how idle reduction benefits health and
  the environment?
• Explain the economic benefits of idle reductions?
• Describe what energy security is and how idle
  reduction can be used to help attain it?
• Explain some suggested actions to utilize idle
  reduction practices?
