Why Do Heavy-Duty Trucks Idle?
3
• To heat and cool the cab and sleeper (and to mask noises while the truck driver sleeps)
• To keep the fuel warm in the winter (avoid cold starts)
• To keep the engine and cab warm while waiting in lines and making pick-ups and deliveries

What Are the Costs and Consequences of Idling?
Idling Is Expensive
•A long-haul, heavy-duty truck typically consumes about 0.8 gallon of fuel/hour.
4
A truck idling 1,800 hours/year for overnight “hotel load” alone will consume about 1,440 gallons of fuel per year.
Annual cost:•$3,600 at $2.50/gal•$4,320 at $3.00/gal•$5,040 at $3.50/gal•$5,760 at $4.00/gal
What Are the Costs and Consequences of Idling?
Idling Increases Engine Wear
•Engine operation = engine wear– Idling lessens time between
required maintenance tasks– Idling lessens time to engine
overhaul

What Are the Costs and Consequences of Idling?
Idling Pollutes
According to Argonne National Laboratory, rest-period truck idling consumes about 1 billion gallons of diesel fuel each year, emitting:
•10 million tons of carbon dioxide (CO2)• Equivalent to the annual emissions of 2.5 million automobiles
•55,000 tons of nitrogen oxides (NOx)•400 tons of particulate matter (PM)

What Are the Costs and Consequences of Idling?
Idling May Be Illegal

•California: 5-minute limitFines start at $300, upper limit $10,000

Technology To Support Idling Reduction
• Auxiliary power units (APUs)• Electrified parking spaces (EPS; also called truck
stop electrification [TSE])• Cooling technologies• Heating technologies• Automatic engine start/stop (AESS) systems
9
Technology To Support Idling Reduction
•Auxiliary power is provided for heat, A/C, electronics, and other devices•May be powered by fuel or battery; may be wayside-power compatible•No federal excise tax; most states have APU weight exemptions

Technology To Support Idling Reduction
Single-system EPS A duct delivers warm or cooled air to a truck. The face of the duct, which is held in place by a window adaptor, also provides an electrical outlet and sometimes an Internet connection and TV services.
Dual-system EPS A wayside pedestal provides electrical power to a truck equipped with plug-in capable equipment. (Called “dual system” because both on-board and off-board equipment is required.)

Electrified parking spaces (EPS)Also called truck-stop electrification (TSE) and shore power

Technology To Support Idling Reduction
EPS: Single System
Provides:•Heating/cooling via duct •Electrical outlets•Internet/TV
No special on-board equipment needed (except inexpensive window adaptor)

Technology To Support Idling Reduction
EPS: Dual System
Provides electricity for EPS-compatible on-board equipment:
•Auxiliary power system•Heater or air conditioner•Other devices
Hourly plug-in rate lower than single-system EPS.

Technology To Support Idling Reduction
Air conditioners cool the cab/sleeper compartment
•Provide engine-off air conditioning powered by energy stored when the truck is running (to charge a battery or freeze a large block of ice)•Increases operational fuel use by only a small amount•May be shore-power compatible•Evaporative coolers are an option for hot, dry climates
16
Technology To Support Idling Reduction
Heaters are inexpensive
•Provide warmth to the cab/sleeper using less than 10% of the fuel used in engine idling •Air heaters supply warm air to the cab/sleeper •Coolant heaters heat the vehicle’s coolant, which, when circulated through the heat system, provides some cab heat
17
Technology To Support Idling Reduction
Engine idle management systems turn the engine off
Idle timer•Turns engine off after a preset amount of idle time
Automatic engine shut-down/start-up system •Turns engine off and restarts it based on cabin temperature and/or battery-charge level
18
Fuel Use, Costs, and Typical Payback
19
Complementary Technologies Telematics/GPS Systems•Provide data about vehicle location and engine status, including idling episodes. •These data allow managers to identify idling patterns and determine which solutions make the most sense.
Cab insulation, window glazing, reflective paint, and passive measures•Can reduce a stationary vehicle’s energy requirements, allowing the use of smaller, lighter, and less-expensive idling reduction equipment (with faster ROI).

Resources: Funding
• National grant, loan, and rebate programs• EPA’s Diesel Emissions Reduction Program (DERA) • Manufacturer rebates and loans• Nonprofit organization programs
• State grant and loan programs• State Clean Diesel grant programs (EPA) and
Congestion Mitigation and Air Quality (CMAQ [DOT]) grant programs
• Programs targeted to assisting small businesses
• Bank loans• Loans can be repaid with money saved on fuel
