Transcript Idle Reduction in Fleets
1
Objectives
Explain how to implement green fleets
Learn about incentives for utilizing idle
reduction technologies and strategies
Learn about the availability and cost of
idle reduction technologies and strategies
Identify the advantages of idle reduction
technologies and strategies
Understand the performance of vehicles
with idle reduction technologies
2
Greening of Fleets
Why use green fleets?
Reduce operating costs
Reduce greenhouse gas emissions
Improve corporate image
3
How to Implement Green Fleets
Get buy-in
Create long-term objectives
Avoid setting reduction goals in absolute
numbers
Anticipate obstacles
Move slowly
Improve vehicle use
Track and report progress
4
Idle Reduction in Fleets
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
5
Transportation and convenience idling
Technologies, policies, practices to
reduce engine idle time
Strategies and technologies to reduce
both transportation and convenience
idling

6
Idle Reduction Strategies
Any reduction in idle time = fuel savings
Avoid traffic by planning trips
Fleet guidelines to reduce idle time
Reductions = immediate savings
7
Idle Reduction Technologies
New technologies, improved fuel
economy and reduced emissions
Light-, medium-, and heavy-duty vehicle
fuel savings
Idle shutoff functions, mild hybrid
technologies
APUs for long haul trucks
TSE implementation
8
Incentives for using Idle
Reduction in Fleets
Incentives
Partnership initiatives and pooled resources
Financial subsidiaries
Informational tools
Initial cost vs. federal and state incentives
American Recovery and Reinvestment
Act (ARRA)
Clean Cities Program
9
Tax Incentives
Federal and state incentives for
alternative fuels and advanced technology
vehicles
Implementation of idle reduction
equipment
Funding and partnership opportunities
for idle reduction technologies

11
Federal Grant Funding
Federal government = largest grant
provider
U.S. Department of Energy (DOE)
U.S. Department of Transportation (DOT)
Environmental Protection Agency (EPA)
U.S. Department of Agriculture (USDA)
12
State Grant Funding
State Energy Office (SEO)
National Association of State Energy
Officials directory
Alternative Fuels Data Center map

13
Idle Reduction Laws
Generally limit the time a vehicle is idling
No idle zones
Schools
Individual rules for each city/area
14

15
Idle Reduction Availability and Cost
Light-Duty
Block Heaters
Utilize grid power to maintain engine
temperature
Heavy-duty vehicles
Reduce problems associated with cold starts
16
Light- and Medium-Duty
Mild Hybrids
Idle shutoff function
Utilizes small battery pack and MG
Small amounts of energy
Onboard energy storage
17
Light-Duty
New Idle Shutoff Technologies
Reduced energy needed to restart engine
One way clutch technology
Micro-hybrid systems
18
Heavy-Duty
HOS requirements
Average truck idles for more than 1,900
hours annually
Truck idling consumes more than three
billion gallons of diesel annually
19
Heavy-Duty
Truck Stop Electrification (TSE)
Electrified parking spots at truck stops
Enable drivers to meet rest requirements
without idling

20
To find an electrified truck stop in
your region, the DOE hosts a site
locator searchable by zip code. It
can be found by visiting
http://www.afdc.energy.gov/afdc/loca
tor/tse.
21
Heavy-Duty
Truck Stop Electrification (TSE)
Single-system vs. dual-system
Single-system offers HVAC, electricity,
internet, cable
Unit is placed in passenger window
Dual-system requires onboard
equipment
Driver plugs truck into outlet to power
onboard equipment
22
Heavy-Duty
Onboard Equipment
Powered by external electrical source or
existing fuel system
More efficient than allowing the engine to
idle
23
Heavy-Duty
Onboard Heating
Direct-fired = small furnaces
Consume only a small amount of fuel per
hour
Coolant heater = heat transfer system
Can be used to heat cabin and warm engine
in cold climates
24
Heavy-Duty
Onboard Cooling
Thermal storage, battery-electric air
conditioners
Thermal storage: energy is stored during
normal operation, used at a later time to
cool cab
Battery-electric air conditioners: powered by
onboard batteries that are charged at truck
stops
Both produce zero local emissions
25
Heavy-Duty
Auxiliary Power Units
Small vehicle-mounted systems
Electrical generator powered by an internal
combustion engine
Powers accessories, HVAC
Heat recapture from ICE
Rechargeable battery packs
26
Strategies
Determine appropriate warm-up time
Know the equipment being utilized in
your vehicle
Turn engine off
27
Cost
Tax benefits for hybrid vehicles
Heavy-duty vehicle modification
incentives
Fuel cost savings will help cover any initial
investment over time
28
Idle Reduction Advantages
Reduced fuel consumption
Fewer vehicle emissions
Lower operating costs
Increased engine life
No-cost implementation of strategies
29
Things to Consider
Possible capital investment
Personal convenience may be
compromised
30
Idle Reduction Performance
Extended engine life
Extended idling adds unnecessary
wear to engine components
Fuel savings helps offset capital costs
Exemptions for added weight from
APUs, etc.
“Green” branding of fleets
31
Performance Summary
• Better fuel economy, an idling vehicle
not in motion achieves 0 mpg
• Reduced emissions
• Similar performance to conventional
vehicles
• May lead to extended engine life
