Why Do Drivers Idle Diesel Engines?
Drivers Idle The Engine:
• To Pre-Heat The Engine and Defrost Before Driving
• To Make Sure Engine Will Start When Needed
• While Waiting in the Cab of Vehicle or Equipment
• To Get Heat in the Bunk While Sleeping
• From Habits That May Be Hard To Break

What’s Wrong With Idling?
Fleet Expenses Related to Idling Vehicles*
Fuel Consumption
• Diesel engines consume about one gallon of fuel per hour
Maintenance
• Idling results in inefficient combustion, increasing soot-load downstream into after treatment
• After treatment plugs requiring regeneration, burning more fuel to clean DPF of soot load
• Increased regeneration decreases life of catalyst filters costing over $1,000 each
Durability –decreased life of these parts
• Fan clutch, air compressor, belts, idler pulleys, alternator, water pump, turbo injectors, after
treatment exhaust system, air cleaners, and EGR valves

Espar makes idle reduction possible!
• Espar offers fuel-operated heaters for engine pre-heat & supplemental cabin heat
for a wide variety of vehicles and equipment from automotive, trucks, buses, to large
construction equipment and military equipment.
Use of Espar heaters allow engine pre-heat and drivers to stay warm without
prolonged engine idling. Fuel-operated heaters do not require any plug in. These
operate with on-board gasoline, diesel, blends, bio-diesel, or natural gas and a small
amp draw on the vehicle battery.
• ESPAR heaters are listed on the EPA website as an idle reduction solution
• ESPAR heaters earned CARB approval
California Air Resources Board--industry standard for low emissions ULEVII
• Espar’s new controllers, Multi Max F-1000 & Digi Max D-1000
recognized as top ten new products for 2012.

Idle Reduction
Saves Dollars
Sleeper Truck Example:
– Diesel fuel costs $4 per gallon*
– Idling consumes approximately one gallon per hour
– Idling for 8 hours per night for heat while driver sleeps
– Cost $32 per night to idle the truck (fuel only)
– 120 average cold nights per year
– $3,840 cost of fuel used to idle one truck per season
THE FIGURES MAY CHANGE
But the message remains the same
IDLE REDUCTION SAVES BIG DOLLARS
*US national average
diesel $3.95 on 4/14/14
