Complex Hydro Carbon
Simple Hydro Carbon
Natural Gas (methane) has
highest hydrogen-to-carbon
ratio of any hydrocarbon

Natural Gas has Many Advantages !
It is
Locally &
Globally
abundant
It costs up to
50% less than
gas or diesel
It is safer
than liquid
fuels
It produces up
to 25% less
greenhouse
gas
It can be
transported
anywhere
Methane (CH4)
Energy Security: Natural Gas is abundant in North America.

New NG drilling technologies are unlocking substantial amounts of
natural gas from shale. U.S. estimated NG reserves have surged by
35% since 2008.
Recent market activity points to “corridors” that support the on highway market for natural gas.

Spark-Ignited Dual-Fuel (DF) High Pressure Direct Injection (HPDI)
Operation Gas and air pre-mixed at low pressure
Air is metered using a throttle
Ignition from spark plug
Uses either an oxidation catalyst or three-way catalyst (lean burn or stoich)
Otto cycle
Gas and air pre-mixed at low pressure
Air may be partially metered using a turbo air bypass or a throttle
Ignition from diesel pilot injection (existing injector of specific pilot injector)
Otto cycle / Diesel cycle
High pressure gas is injected directly in the combustion chamber
No intake throttle
Ignition from specific diesel pilot injection
Diesel cycle
Fuel System Notes
100% NG
CNG or LNG
No run on diesel capability
Typical substitution of 50~60% over duty cycle

What is Stoichiometric Combustion?
Ideal combustion process where fuel is burned
completely
– Ideal air/fuel ratio - chemically correct mixing of fuel and air
– Consumes all fuel & air without excess of either in exhaust
– No Oxygen in exhaust stream allows Three Way Catalyst to
handle NOx control
Benefits:
– Increased power density
– Increased thermal efficiency
– Decreased emissions

The Westport HD Engine
Cummins Westport Confidential 34
• Liquefied Natural Gas (LNG) fuelled heavy-duty engine
• Cummins ISX base engine platform from 2009
• Compression ignition - High Pressure Direct Injection
(HPDI) of natural gas
• High diesel substitution (95-97%)
• Diesel Engine Performance: - Same high power and torque - Same or higher efficiency
• EPA/CARB 2010 certified
Westport HPDI Methodology
• Operates in a very similar manner
to a normal diesel engine
• Compression ignition –
no spark plug
• Natural gas injected at
high pressure at end of
compression stroke
• Diesel Engine Performance
remains
– Same high power and torque
– Same or higher efficiency
High Pressure Direct Injection
Directly replaces diesel injector
Common-rail style
Independently injects diesel and gas at up to 4500psi injection pressure
Diesel used as an ignition source, actuation fluid, lubricant, and coolant Diesel HPDI

Q4 2012
Q1 2013
Are there any special service requirements for natural gas vehicles?
Yes.
– Dealer facilities may need to be modified to meet
building and/or fire codes.
– Technicians need to be trained and certified on
natural gas components.
• Fuel System
• Engine
Cummins Westport Confidential Dec 2011
Natural Gas Shop Upgrades
As a reference the National Fire Protection Agency
publishes an industry standard (NFPA 30A) for NGV
facilities.
– Also have guidelines for installation and inspection of NG fuel
systems on vehicles (NFPA 52)
– Both are available at the website - NFPA.org
Local building codes and regulations vary by location
– Consult with industry experts and local fire marshals and officials.
Cummins Westport Confidential Dec 2011
Natural Gas Shop Upgrades
Highlights of Repair Facility Guidelines
– Methane Gas Detection System
• Sounds an alarm, deactivates heating systems,
and activates a mechanical ventilation system (i.e.
opens bay doors and roof vents, fans etc)
– Air Handler System
• Opens doors and circulates/evacuates air within
the shop to prevent accumulation of methane
– Electrical Upgrades
• All electrical relocated to be at least 18” below the
ceiling
– Open Flame Heater Restrictions.
