§  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 .

Interest in idling…

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

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”.

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.

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 .

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.

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

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

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 .

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 .

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 .

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 .

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; 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.

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……

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.
