Why Choose the MaxxForce 10?

• Light Weight Design
• Built on a our premium medium duty platform, the
  MaxxForce 10 has a big advantage in weight
  sensitive applications
• Dry Engine Weight (advertised)
• Cummins ISM 2181 lbs
• C-13 2270 lbs
• MaxxForce 10 1560 lbs
• 600-700 lbs advantage!

7
Why Choose the MaxxForce 10?

• Low Cost Alternative to a Heavy Engine
• A MaxxForce 10 powered International WorkStar
  will generally cost more than 8000 less than a
  similarly speced WorkStar with a heavy engine at
  the same rated power

8
Why Choose the MaxxForce 10?

• Low Cost and Driver Friendly
• Allison 3000 HS and 3000 RDS transmissions are
  now available with the MaxxForce 10 up to 350 HP,
  offering considerable savings over the 4000
  series transmission required for heavy engines
• Eaton automated manuals are also available for
  the MaxxForce 10, providing another cost
  effective driver friendly alternative

  cylinder pressures

11
MaxxForce 10 - Construction
Crankcase Premium Strength

• Bearing cap ladder provides added strength
• Ties main bearings to skirt of crankcase
• Provides added strength, maintaining perfect
  alignment of crankshaft under heavy loads

12
MaxxForce 10 - Construction

• Crankshaft Heavy Duty Durability
• Main bearings comparable in size to Heavy Engines
  and significantly larger than competitive 9
  liter engines

ISL 3.83
13
MaxxForce 10 - Construction

• Single Piece Steel Piston
• Heavy engine style piston
• Similar to MaxxForce 11/13 piston
• Gallery cooled
• Improved wear characteristics and lighter over
  all weight compared to prior two piece steel
  crown / aluminum skirted piston

14
MaxxForce 10 - Construction

• Titanium Compressor Wheel
• Severe Service Turbo-Charger

MaxxForce 10 engines use a titanium compressor
wheel for durable turbo service in the most
severe applications
Electronic Variable Response Turbocharger
15
2007 Technology and Improvements

• Design Philosophy for 2007
• Minimize changes
• Carry-over 2004 engine technology to maximize
  reliability growth
• Integrate proven technology and build from Green
  Diesel Technology experience to meet emissions

16
2007 Technology

• G2 Electro Hydraulic Fuel System

• Advantages
• Reliable proven design
• Full electronic control
• No high pressure fuel lines
• Enables DPF regeneration (in-cylinder-dosing)
  without down-stream injection equipment

• Low pressure common rail delivers fuel to
  injectors
• High pressure common oil rail - provides
  injection force
• G2 Injectors
• Spool valve controls oil flow and injection
  events
• Delivers fuel at 71 intensification of oil rail
  pressure

17
2007 Technology

• G2 In-Cylinder-Dosing for DPF Regeneration
• Added exhaust heat occasionally required to
  oxidize particulate matter trapped in the Diesel
  Particulate Filter
• G2 injectors deliver a second dose of fuel after
  combustion is complete
• This unburned fuel is pushed out of the cylinder
  with the exhaust
• Fuel then oxidizes in a flow through catalyst,
  releasing heat
• Heat reduces soot deposits in the DPF to CO2 and
  Water
• No additional fuel lines or injection equipment
  is required

18
2007 Technology

• DPF Regeneration
• Intake throttling and turbine vane control

• Throttle wide open during normal operation
• Engine throttling along with turbine vane control
  raises exhaust temps for active regeneration
  prior to in-cylinder-dosing
• Throttle can close to protect DPF from high
  temperature damage

Intake Throttle
19
2007 Technology

• Electrical System

• New 32 bit single box ECM
• Faster computer with more capability
• Needed for aftertreatment inputs and control
• Single box has fewer connection points than old
