Transcript Idle Reduction

1
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
2
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
3
 Transportation and convenience idling
 Technologies, policies, practices to reduce
engine idle time
 Strategies and technologies to reduce both
transportation and convenience idling

4
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
5
Consumers
 Purchase vehicles with idle reduction
technologies
 Modify driving habits
 Plan trips to avoid traffic
 Consult the owner’s manual for optimal
vehicle operation
6
Advantages of Idle Reduction





Reduced fuel consumption
Fewer vehicle emissions
Lower operating costs
Increased engine life
No-cost implementation
7
Additional Points to Consider
 Possible capital investment
 Personal convenience may be compromised
 Be aware of local idling laws
8
Benefits of Idle Reduction
 Health and environmental rewards
 Reduced fuel costs
 Reduced dependence on foreign oil
9
Health Benefits
 Combustion of fuels produces harmful
emissions
 Creation of PM and NOx
 Respiratory and cardiovascular
complications
 Idle reduction reduces vehicle emissions
10
Environmental Benefits
 Emissions negatively affect the
environment
 GHG formation, climate change
 Idle reduction = reduced emissions
11
Economic Benefits
 Excessive idling = unnecessary financial
loss
 Industry opportunity for implementation
of idle reduction technologies
 Reduced consumption = financial benefit
for all drivers
12
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
13
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
14
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
15
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 1030 seconds as recommended by the California
Consumer Energy Center
 Implement heavy-duty technologies if available
 Utilize TSE locations

Test Your Knowledge
1. True or False: The fuel economy of a
conventional vehicle idling while it sits in traffic
is 0 MPG.
2. Nearly ________% of the petroleum
consumed in the U.S. is used for transportation.
3. The California Consumer Energy Center
recommends turning off an engine if the vehicle
is to idle more than 10 (seconds, minutes).
