GoGreen Communications has posted this important documentation in support of its market-leading research and practice on idle reduction. GoGreen is focused on driver behavior modification training, certification and branding for fleet operators. GoGreen’s Point of View on Idle Reduction. As of September, 2020, idle reduction from driver behavior modification in a fleet’s gasoline and diesel-burning assets, is the biggest combined cost reduction, greenhouse gas reduction, and air pollution reduction opportunity for fleet operators in the United States and Canada in all fleet industry sectors. Further, GoGreen believes that cost reduction, greenhouse gas reduction and air pollution reduction should be a fleet operator’s priority at this time of economic crisis, accelerated climate change, and a lung virus pandemic. Currently, idle reduction is not an area of priority for most operators (GoGreen is actively surveying the market, documenting the barriers to creating an idle reduction fleet culture). It is GoGreen’s view that the typical addressable opportunity for North American fleet operators who have not addressed driver idling behavior (as an aggregate of all fleet industry sectors and all fleet departments) is about 40% of engine hours and its associated downstream cost impact on operation and maintenance expenses* This assumes driver idling behavior only and excludes ‘PTO’ or business function idling in park. GoGreen has identified the following cost metrics regarding driver idling behavior: Fuel. Added maintenance, lost warranties. Lifecycle costs. Vehicle downtime. Employee productivity. Carbon emissions. Air quality. Safety risk (vacant vehicle idling). Fleet reputation.

1. Idling Myths
How Much is Enough?
Presented by:
Ross Somerville
Cummins Western Canada

2. Topics
§ History: It all started out good.
§ Who started this practice?
§ Myths & Facts.
§ Impacts on the engine from idling.
§ How much is enough?
§ New Technologies to reduce idling.
§ Q & A .

3. Interest in idling…

4. How did this nasty habit start?
§ 1932 First Diesel Powered Truck
§ Massive diesel engines had very
high parasitic loads
§ Engine oils were heavy and
created “drag” when cranking
§ Static injection timing made
diesels poor starting engines
§ Heat was needed for
compression and ignition

5. How did this nasty habit start?
§ Poor batteries & cranking systems
did not guarantee the next start
§ Fuel was cheap
§ Cab heat was poor
§ Air Conditioning Option
§ Air brake storage tanks leaked
§ Solution: “Just let it idle”.

6. Who started it?
Ø The owners – needed reliable deliveries
Ø The manufactures – poor starters
Ø The industry “experts” – created fear
Ø Operators – truck stop myths and tales.

7. Myths & Facts
D Diesels must idle or they won’t restart
D Diesels create more heat by idling
D Diesel don’t burn much fuel at idle
D Its good for the engine to idle it
D The neighbours don’t mind .

8. Impacts of engine idling
§ It’s a fuel economy penalty = 2.5 – 4.5 litres per/hr
§ It’s the most inefficient mode - emissions
§ Fuel contamination of lube oil is high at idle
§ Cylinder wall wear is accelerated by “wash down”
§ Short term idling actually “over cools” the engine
§ Engine life can be reduced by up to 20%
§ 500 hrs of idling = 64000 miles of wear
§ Noise emissions.

9. How much is enough?
§ Realistic goal of 10% or less
– 3-5 mins. only after a hard pull (temp stabilization)
§ Poor Example:
– 30% Idle (non revenue generating time)
– 888 gals burned at idle
– Idle cost for fuel only @ $3.64 / gal = $3232.00
§ Good Example:
– 7% Idle (non revenue generating time)
– 256 gals burned at idle
– Idle cost for fuel only @ $3.64 / gal = $932.00

10. New Technologies
ü Owner & Driver Education “Best”
ü Driver can adjust low idle speeds 600 – 800 RPM
ü Electronic torque limiting when vehicle is not moving
ü Programmable Idle Shutdown = 3 – 60 mins.
ü Electronic Driver Reward Systems = rewards for good
behaviour with more speed or horsepower

11. New Technologies
ü Idle Control Systems:
• Does not require a driver in the vehicle
• Automatically starts and stops the engine at idle
• Goal is to maintain block temp of 16 C in cold
temps (49 C oil temp)
• Maintain a minimum battery voltage for starting
(12.2 volt activate)
• Maintain a pre set “sleeper” temperature .

12. New Technologies
ü High Output Block and Oil Pan Heaters
ü Auxiliary Gensets 4-5 kW, = AC & Heater
ü Diesel fired heating systems
ü Cylinder cut out technology
ü Introduction of ULSF & Diesel Particulate
Filters .

13. Summary
L Idling wastes fuel
L Idling reduces engine life
L Idling generates harmful emissions
L Idling is a revenue negative operation
J Idling can be minimized .

14. My last words…
Diesels have made great progress compared to 1970
Today’s Heavy Duty Truck Diesel:
C 100% more power
C 50% better fuel economy
C 400% longer engine life
C Costs 50% less in constant dollars
C Most importantly it has 90% reduction in
exhaust emissions .

18. Rock Solid Rules
§ Idle time is costly!
Every HOUR of idle time can
decrease fuel efficiency by 1%.
§ Less Idling decreases fuel
consumption resulting in
less emissions (GHG), and
a smaller carbon footprint.
§ Idling increases maintenance and
reduces component durability.

19. Cost of Engine Idling – Fuel Consumption
§ Idle time can significantly affect the vehicle’s fuel efficiency.
§ Overall, Up to 10% impact on MPG.
§ The vehicle uses the most diesel fuel when
the engine runs and the truck doesn’t move.
§ Idle/PTO fuel consumption increases exponentially
with engine speed. Almost double with SCR Engines.
Idle/PTO Fuel Consumption
Engine Speed RPM Average Fuel Consumption (Gal/Hr)
650 ~0.5
1000 ~1.0
1200 ~1.5
§ When idling is necessary to maintain cab/bunk compartment
temperatures, select the lowest idle speed possible
to maintain cab heat.
§ Select the lowest idle speed possible to
maintain engine temperature of 140 F Degree
in winter operation.

20. Cost of Engine Idling – Maintenance
§ AFTERTREATMENT
– Idling results in inefficient combustion, increasing your
soot-load downstream into your AFTERTREATMENT.
– AFTERTREATMENT plugs; requiring a REGENERATION;
burning MORE diesel fuel to clean DPF of soot-load.
– Increased regenerations decreases the life of the
catalyst filters. $1,500-2,000/each.
– Today You pay in fuel THREE times for extra idling.
§ ENGINE FAN
– If fan is engaged during idling, it results in additional
fuel consumption.
– Creates a dust-storm under the hood,
reducing air-cleaner life AND engine life.
– Reduces Fan Clutch life for when you really need it –
to cool down the engine.

21. Cost of Engine Idling – Durability
§ While the engine is running,
You are wearing-out all of these
components prematurely:
– Air-compressor
– Fan Clutch
– Belts and Idler Pulleys
– Alternator
– Water Pump
– Turbo (very expensive turbo today)
– Injectors (thru increased regenerations)
– Aftertreatment Exhaust System, and components
– Air Intake system: Air cleaners, EGR Valves
– Every part on the engine……

22. How do I reduce Idling?
• Shut it off !
• Utilize Electronic Engine Controls
• Auxiliary Heaters
• Diesel Fired Heaters; set on timer
• Electric Heaters via Shorepower
• DC Battery Power Units Heat/AC
• APU’s for Hotel loads
• Don’t bump-up Idle speed.

23. Programmable Engine Features
§ Idle Shutdown
§ Idle Shutdown in PTO
§ Idle Shutdown Override
§ Ambient Temperature Shutdown Override
§ Driver Reward

24. How do I manage Idling?
§ You can’t manage anything
without an effective means to
measure it.
§ You can’t change behaviors
unless you have good data
to validate your goals.
