Exhaust emission standards for CO 2 for tractors above 26,000 pounds GVWR Limit is somewhere between 73-66 g/ton-mile for class 8 sleepers – High roof compliance is under 72, medium roof is 73 and low roof is under 66 Credit for having idle reduction technology (5g/ton-mile) – Worth anywhere from ~7% to ~7.5% of the total compliance burden. Class 8 tractor types, though the high roof tractors tend to have the most aerodynamic drag – Sometimes necessary to have the idle reduction tech to comply with the regulations Automatic engine shutdown systems. Extended idle reduction credit is NOT necessary to comply in many cases. – Tractor is using efficient tires and a low speed limiter then it will comply in the vast majority of cases. – If for some reason the tires were less efficient or the speed limiter was set higher, the extended idle reduction of 5 g CO2 per ton-mile is significant (77.5% of compliance depending on the tractor type) and could be used to offset less efficient aspects in other parts of the truck

Battery-Electric Auxiliary Power Systems Using advanced battery packs, battery-electric auxiliary power systems provide heating, cooling, and electrical power to ancillary cab appliances. The battery packs require approximately 2-6 hours of charge time and can run the air conditioning system for up to 12 hours per full charge. Vehicle-Battery Systems Vehicle-battery systems are less expensive alternatives more commonly used in day cab applications. Truck Stop Electrification (On-Board Power Infrastructure) By installing on-board electrical hardware and an electrically-powered climate control system, drivers can "plug in" their vehicles and draw electricity directly from the power grid. Truck Stop Electrification (Off-Board Power Infrastructure) For an hourly fee, providers may offer heating, cooling, television service, telephone service, and internet service through a duct that attaches to the vehicle through an adapter (one-time purchase) fitted into the vehicle's side window opening. Thermal Energy Storage Systems A Thermal energy storage system stores cooling energy from the vehicle's air conditioning system during normal road operation. Diesel-Fueled Auxiliary Power Systems Diesel-fueled auxiliary power systems use small diesel engines to generate power for cab heating, cab cooling, and operating ancillary cab appliances. These units can also be used to heat the engine block in cold weather and recharge the vehicle's battery. Because of the engine's smaller size, operating a diesel-fueled auxiliary power system uses only a fraction of the fuel that would be used by idling the vehicle's primary engine Fuel-Fired Heaters (Fuel Operated Heaters) http://www.arb.ca.gov/msprog/cabcomfort/cabcomfort.htm

Tractor Impact … by the numbers… •

Use of an APU has a significant impact on the tractor engine – Idle reduction reduces engine maintenance • Low load idling fills the DPF resulting in more frequent regenerations • Which results in more frequent professional servicing of the DPF – Reduced engine hours increases resale value of the tractor “Idling Myths. How much is enough?”- Cummins – 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. Unscheduled DPF maintenance = lost time, lost revenue.
Tractor Impact … by the numbers… • TK Customer Experience – Dedicated to the use of APUs on entire fleet – Benchmarks against a large non-APU fleet – 5% DPF failure rate over life of vehicle compared to 80% by non-APU fleet – Decreased engine hours by 12,000 hours • 1.5% idle time
– Increased resale value of truck by $5,000 – Increased tractor oil change from 30,000 miles to 45,000 miles due to lack of idling contamination

Electric APU System • Education is key for success with a non-engine based solution the driver will need to follow a best practices approach • Do – Pull down with tractor engine – Do keep curtains closed – Do keep sleeper curtain closed – Turn off accessories when not being used – Keep tractor out of direct sunlight if possible • Don’t – Run AC or accessories when not in tractor – Run with windows cracked open – Run external marker lights 8
Electric APU System • Battery Systems Require Driver Retraining Regarding the use of Hotel Accessories – Hot pad or coffee maker • Always on will deplete the batteries – TV and lights • If you don’t need them, turn them off – Microwave • Smaller wattage units likely required

TriPace Electric Auxiliary Idle Reduction • Is an all- electric system right for you? – Desired Run Time – Ambient conditions – Hotel Loads – Recharge Requirements • To be successful, an electric APU must deliver three attributes: – Reliability – Efficient HVAC – Superior Power Management • Smart Charger Module technology on TriPace – Provides individual charging and discharging management for each battery – Provides 3-Stage charging profile to optimize performance and extend NXT battery life – Maintains balance between tractor and APU batteries during HVAC operation 10
TriPac Evolution Diesel-Fueled APU
• Is an Diesel fired system right for you? – Desired Run Time – Hotel Loads – Ambient conditions – Recharge Requirements – Tractor Engine run hours – Particulate – Maintenance – Fuel Savings
