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.

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.

Cost of Engine Idling – Maintenance

AFTERTREATMENT– Idling results in inefficient combustion, increasing your

soot-load downstream into your AFTERTREATMENT.

– AFTERTREATMENT plugs; requiring a REGENERATION; buring 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.

Cost of Engine Idling – DurabilityWhile 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……

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.

Programmable Engine Features

Idle Shutdown

Idle Shutdown in PTO

Idle Shutdown Override

Ambient Temperature Shutdown Override

Driver Reward

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.

Summary….

You do the math…..

Every Drop of fuel saved goes

right to the bottom-line $ $.

You pay three times in fuel

burned for Idling today.

Reduce Green-House Gases.

Reduce Maintenance Costs.

The days of casual Idling are over…..

Delivering the right technology with

the right support …. On time, EveryTime.

Depend On Cummins! THANK YOU.
